How to connect Android to a TV (screen mirroring and casting)
One of the greatest ways to take advantage of your Android phone’s full potential is to view your favorite movies, pictures, or simply browsing apps on a larger screen.

Fortunately, it’s now simpler than ever to connect your Android to a TV, whether you want to mirror your phone’s screen, stream YouTube, or display vacation images. Using built-in features like screen mirroring, Chromecast, and HDMI adapters, we’ll go over several methods in this article for connecting your Android phone to a TV—both wirelessly and with cords. Third-party apps are not necessary.

Check your TV compatibility

Before you start, it’s important to know what kind of TV you’re working with. Most modern TVs support one or more of the following:
- Smart TV with built-in casting (e.g., Android TV, Samsung Smart TV, LG WebOS)
- TV with Chromecast built-in
- TV with HDMI port and no smart features
Also, for wireless option, your Android phone and smart TV should be on the same Wi-Fi network and running Android 5.0 or later.

Use native casting with Chromecast or smart TVs

Most Android phones come with built-in support for casting via the Google Cast protocol. Here’s how to use it:

Steps:
1. Connect your Android and smart TV to the same Wi-Fi network.
2. Swipe down from the top of your Android screen to open Quick Settings.
3. Tap Cast or Screen Cast.
4. Your phone will search for compatible devices. Select your TV or Chromecast from the list.
5. Your screen will be mirrored onto the TV. You can now open apps, play videos, or browse the web.
✅ Best for: Watching YouTube, streaming apps like Netflix, showing off photos.

Note:

YouTube is one of the apps that has its own cast icon. You can select your TV without full screen mirroring by tapping the cast symbol in the upper-right corner.

Use Samsung’s Smart View or SmartThings

Wireless casting is made easy using the Smart View or SmartThings app if you own a Samsung Galaxy phone and a Samsung Smart TV.

Steps:
1. Open Settings > Connections > Smart View on your Samsung device.
2. Select your compatible Samsung TV.
3. Tap Start now to begin mirroring.
As an alternative, you may connect to manage your TV, cast media, or mirror the screen using the SmartThings app, which comes pre-installed on newer models.

✅ Best for: Samsung users who want the most integrated experience.

Miracast (for supported devices)

Miracast, a wireless display protocol that reflects your screen, is supported by a large number of non-Google Android devices (such as LG, Huawei, and older phones).

Steps:
1. On your TV, enable Miracast or Screen Mirroring mode.
2. On your phone, go to Settings > Connected Devices > Cast.
3. Choose your Miracast-enabled TV or dongle from the list.
Your phone may not display the choice at all if it lacks native Miracast functionality. If so, try some of the other techniques in this tutorial.

✅ Best for: Older smart TVs without Chromecast but with Miracast support.

HDMI cable with a USB-C to HDMI adapter

If your TV isn’t Wi-Fi enabled or you prefer a connected connection, a USB-C to HDMI converter provides a convenient plug-and-play option.

Steps:
1. Get a USB-C to HDMI adapter (make sure it supports video output).
2. Plug the USB-C end into your Android phone.
3. Plug an HDMI cable into the adapter and then into the TV.
4. Switch your TV to the correct HDMI input.
The screen of your phone should show on the TV after it has been connected. In the display settings of certain phones, screen mirroring must be enabled.

✅ Best for: TVs without smart features or Wi-Fi access.

Troubleshooting
- Make sure both devices are on the same Wi-Fi network.
- Restart your phone and TV if the device doesn’t show up.
- For wired connections, ensure the adapter supports video output (some cheap models only support charging).
- For best performance, avoid mirroring heavy 3D games—use casting for videos and apps instead.
A whole new realm of efficiency and fun is made possible by connecting your Android phone to a TV. The technique is easy and doesn’t require any specialized software or gear, whether you’re playing mobile games, presenting slides at work, or binge-watching on a larger screen. Your phone is ready to go large wherever you are if it has native support for Chromecast, Miracast, or a simple HDMI adaptor.

3. Toggle on “USB debugging”
4. Confirm the prompt asking if you’re sure
That’s it! You can now use your phone with development tools or perform more advanced actions from your PC.

When should you turn off USB debugging?

If you’re not actively using USB debugging, it’s best to leave it off. Here’s why:
- USB debugging can be a security risk if your device falls into the wrong hands while unlocked.
- Some apps or company policies block access if USB debugging is enabled.
To disable it, just return to Developer Options and toggle it off.

Other useful Developer Options settings

Besides USB debugging, some other features you may want to explore include:
- Window animation scale / Transition animation scale: Set to 0.5x for faster UI response
- Force activities to be resizable: Useful for multitasking and split screen
- Stay awake while charging: Keeps the screen on during testing
- Limit background processes: Improve performance by reducing multitasking
- Show taps / Pointer location: Great for app demos or screen recording
Be cautious while experimenting—many of these options affect system behavior.

Troubleshooting Developer Options or USB debugging

Developer Options not appearing?
- Double-check that you tapped “Build number” exactly 7 times
- Some devices require a reboot afterward
USB debugging not working?
- Try a different USB cable or port
- Make sure “File Transfer” mode is selected via USB preferences
- Check that your computer has proper ADB drivers installed
You may access a robust collection of tools on your Android phone by turning on USB debugging and Developer Options. Although developers are their main target audience, tech-savvy consumers who desire greater control over their gadget might also benefit from them.

These options can improve your Android experience, whether you’re using ADB to transfer files, debug apps, or simply wish to adjust animation speeds. Just use caution when navigating the options, since some settings may have unexpected consequences.

How to fix the battery drain on Samsung Galaxy devices running One UI 7
Running on Android 15, Samsung’s One UI 7 version boasts a new interface along with several new capabilities. One of the unanticipated issues that many customers have seen with the One UI 7 is shorter battery life.

Even with minimal use, Samsung customers report that their Galaxy phones are having trouble lasting a full day. This article examines the sources of the battery life issues that were noticed following the One UI 7 update, as well as solutions.

One UI 7 battery drain isssues from the rollout

Owners of Samsung devices have frequently complained about severe battery drain on websites such as Reddit, X/Twitter, and Samsung Community Forums.

One user of a Galaxy S24 Ultra, for example, reported that the screen-on time of their phone decreased to roughly 5 hours from 6–7 hours before to the update.

Another owner of a Galaxy Z Fold 6 claimed that by the end of the day, their battery had dropped from 45 to 50 percent to 20 to 25 percent.

Some users of the Galaxy S23 series have claimed similar issues, requiring two or even three daily charges for simple tasks like browsing or viewing movies.
Rephrase

As the device becomes used to the new software, the post-update optimization period typically lasts a few days to a week, but the problem seems to last longer.

Users have also reported related issues, like slower app loading times or phones that run warmer than normal, which could be a factor in the higher power usage.

Why is the drain occurring?

While Samsung has not officially confirmed the cause, several factors could explain the battery drain. Since One UI 7 is a major software update, its new features, animations, and background processes may have been demanding more power.

User-installed third-party apps may not have been fully optimized with the new OS, causing battery drain. Another possibility is that background processes, such as system optimizations or data syncing, are running more frequently than needed.

The solution

If you’re experiencing battery drain after updating to One UI 7, here are some practical steps to try:

Clear the cache:
- Go to Settings > Device Care > Storage and clear the cache for apps.
Enable Light Performance Profile:
- Found in Settings > Battery and Device Care, this mode reduces performance to save power.
Turn off AOD:
- Disable Always On Display, reduce screen brightness indoors, or switch to Dark Mode to conserve battery.
Update Apps:
- Ensure all apps are updated, as outdated versions may not work well with One UI 7.
Factory Reset (last resort):
- Some users report improved battery life after a factory reset, though this requires backing up data and reinstalling apps.
You’re not alone if the One UI 7 upgrade has caused your Galaxy device’s battery life to suffer. You can handle the problem while you wait for a possible solution by attempting the aforementioned procedures and keeping an eye on Samsung’s reaction.

How to back up your Android phone
Backing up your Android phone ensures that your data is safe in case of loss, damage, or switching to a new Android device. Thankfully, Android has a number of built-in security features that secure your contacts, media, apps, and settings without the need for third-party programs.

Establishing a suitable backup plan is crucial, regardless of whether you’re upgrading your device or getting ready for a factory reset.

Why it’s important to back up your Android phone

It’s not just techies who should back up. You run the danger of losing private images, critical messages, app data, and even saved Wi-Fi passwords if your phone is misplaced or broken. Regular backup creation allows you to:
- Restore your settings and apps to a new device
- Avoid data loss in case of malfunction or theft
- Free up storage by offloading files to cloud services
Use Google backup (cloud-based method)

Google offers a dependable, integrated backup system that connects to your Google account and stores your important data in the cloud. For the majority of Android users, it is the most practical approach.

What Google backup saves:
- App data and preferences
- Call history
- Contacts
- SMS text messages
- Device settings (Wi-Fi, wallpapers, display preferences)
- Photos and videos (via Google Photos if enabled)
How to enable Google backup:
1. Open Settings on your Android device
2. Scroll down and tap Google
3. Tap Backup
4. Ensure Backup by Google One or Back up to Google Drive is turned on
5. You’ll see a summary of what’s being backed up. Tap Back up now to trigger an immediate backup
Once enabled, your phone will automatically back up daily when connected to Wi-Fi and charging.

Back up photos and videos using Google Photos

Your videos and pictures frequently include priceless memories. To make sure your media files are securely backed up and available on multiple devices, Google Photos offers a quick and safe solution. It’s among the most dependable ways to preserve your graphic information without requiring complicated instruments or extra hardware.

Google Photos is a robust cloud-based platform that automatically stores and arranges your images and videos, making it more than simply a gallery app. Once activated, it will sync your media to your Google Account continually, so your memories will be preserved even if your device is lost or damaged.

Steps to back up media:
1. Open the Google Photos app
2. Tap your profile icon in the top right
3. Choose Photos settings > Backup
4. Toggle Backup to on
5. Choose your preferred upload size (Storage saver or Original quality)
All your photos and videos will sync to the cloud, and you can access them on any device logged into your Google account.

Back up files manually to a PC

Although cloud storage services like Google Drive and Google Photos are convenient, backing up your Android files to a PC by hand offers you more control, privacy, and independence from internet connectivity. It’s a simple process that guarantees you have a hard copy of all of your vital information, including documents, films, images, and more, safely saved on your computer.

Here’s how:
1. Connect your Android phone to your PC using a USB cable
2. On your phone, choose File Transfer / MTP mode when prompted
3. Open File Explorer on your computer
4. Locate your device, open it, and navigate to folders like DCIM, Downloads, Pictures, or Documents
5. Copy and paste the desired files to a safe folder on your PC
This method is ideal for archiving large files or performing a one-time back up your Android without an internet connection.

Use Samsung Cloud or manufacturer tools (for Samsung, Xiaomi, etc.)

Some manufacturers offer their own back up your Android device solutions in addition to Google’s.

For Samsung users:
1. Go to Settings > Accounts and backup
2. Tap Samsung Cloud
3. Choose what to back up (contacts, calendar, settings, etc.)
4. Tap Back up now
You can restore this data to any Samsung device later using the same Samsung account.

Xiaomi users:

Use Mi Cloud by going to Settings > Mi Account > Mi Cloud and enabling the backup options available for your account.

Always ensure you’re connected to Wi-Fi and have enough cloud storage before initiating the process.

Backup apps like SMS and call logs (optional)

Most devices now have SMS and call history included in Google’s backup system, but if you have an older phone or want more redundancy, apps like SMS Backup & Restore can give you more flexibility.

How to restore your data

When setting up a new Android phone:
1. Log in with the same Google account used for backup
2. During the setup process, Android will detect the backup
3. Choose what you want to restore—apps, settings, contacts, etc.
4. Wait for the process to complete; some data may take time to sync
For manufacturer backups, you’ll need to use the brand-specific restore method (Samsung Cloud, Mi Cloud, etc.).

Tips for reliable Android backups
- Always use a stable Wi-Fi connection before backing up
- Keep automatic backups turned on for peace of mind
- Occasionally perform a manual backup if you’re making major changes
- Regularly check if Google Photos is syncing properly
- For local backups, organize files by folders and label your backups by date
Back up your Android device is easy and doesn’t require technical expertise. The majority of your crucial data is handled by Google’s reliable, automated solution, but you also have more flexibility with local and manufacturer-specific solutions. Having a backup guarantees that your data is never completely lost, whether you’re changing phones or simply staying secure.

6 useful connectivity features you should know
Connectivity features enable communication between networks and devices. Numerous tools are available on Android, with Bluetooth, Wi-Fi, Near-Field Communication, and mobile hotspot being among the most widely used. There are very few users that do not utilize any of them in a given day.

You might be using a wireless connection to watch videos or pair your wireless headphones with your phone. You may be surprised to learn that there are more features available to improve your experience. Let’s examine your device’s settings in more detail and get you using them immediately.

Use QR code to share your internet connection

It’s uncomfortable to pause what you’re doing, type or speak out your Wi-Fi or mobile hotspot password, and ensure sure no one else can see or hear it. Use a QR code if you want to share it more quickly. Here’s how:

For wi-fi network
- Go to Settings > Wi-Fi.
- While your device is connected to a network, tap the information icon beside the network.
- Tap Share. You may need to enter your security method to continue.
- You should see a QR code. It’s a square filled with a black and white pattern.
- From the device you’re sharing to, access the QR code tile from Quick Settings.
- Scan the QR code to get access immediately.
Mobile hotspot password
1. Open Settings.
2. Go to Network & internet or Connection & sharing.
3. Tap Hotspot & tethering or Personal hotspot.
4. Tap the toggle button to enable hotspot.
5. Tap the tiny QR code icon beside the hotspot name. You should see the enlarged version after entering your security unlock method.
6. On the other devicce, access the QR code tile from Quick Settings and scan it to gain access.
Share files to iPhone wirelessly

It can be frustrating and difficult to move files and data between the iOS and Android environments. Due to Apple’s closed-off ecosystem design, cross-platform compatibility necessitates a significant amount of manual labor. Although it is incompatible with iPhones, Quick Share for Android is an alternative to Apple’s AirDrop. But on Android 15, OnePlus’ new Share with iPhone feature unites the worlds of Oppo, Realme, and OnePlus devices. Since the receiving device needs to download the O+ software in order to connect, the solution isn’t entirely native. Nevertheless, it’s quick and not too difficult. To utilize it, follow these steps:
1. Open Settings.
2. Go to Connection & sharing.
3. Select Share with iPhone. Then tap the toggle button to turn on the feature.
4. On the iPhone, install the O+ Connect app from the Apple App Store. Then open it and turn on Bluetooth.
5. Select the files you want to send from either phone.
6. You should see the detected devices while preparing to send them. Tap your preferred device.
7. Accept the transfer request on the receiving device. The files should arrive in seconds, depending on the size.
Use Wi-FI calling and texting

Signals from routine phone calls and texts travel through cell towers before they are received by the recipient. Connecting with individuals will be difficult if you’re in a rural location far from a cell tower or in a building with high walls. Use Wi-Fi calling instead for better outcomes. Your phone uses Wi-Fi to send a message or make a call over the internet, avoiding the cell tower, as long as you have access to a Wi-Fi network. To utilize it, follow these steps:
1. Ensure that Wi-Fi is turned on and you’re connected to a network.
2. Open the Google Phone app.
3. Tap the three-dot icon in the upper-right corner. Then select Settings.
4. Tap Calls.
5. Select Wi-Fi calling.
6. Turn on the toggle button beside Use Wi-Fi calling.
Use your phone as a PC webcam

The size of the camera sensor and lens is constrained by the tiny area in the top bezel of a laptop. PC cameras are typically blurry and uninteresting for proper video calls because of this. Thankfully, your phone has more space for wider apertures and larger sensors, which provide sharper images. With Android 14, you can now take advantage of that feature and use your smartphone as a camera. It was enhanced with Android 15’s high-quality mode. To enhance your virtual meetings using the functionality, take the following actions:
1. Connect your PC and phone with a USB cable. You should see a notification on your phone recognizing the connection.
2. Tap the notification and choose to use USB for Webcam.
3. Tap the HQ button in the upper-right corner of the call screen to use High Quality mode.
Activate Bluetooth automatically every day

iOS has had automatic Bluetooth activation for many years. It is only temporarily disabled when you disable it from the Control Center. Unless you disable the option from the settings menu, it reactivates. Keep it on if you’re constantly connecting to Bluetooth speakers, earphones, or even your automobile, even though most people find it annoying. The automation setting was first available on Pixel phones running Android 15, and it might eventually be available on other devices. Here’s how to make it active:
1. Open the Settings app.
2. Go to Connected devices > Connection preferences.
3. Tap Bluetooth.
4. Turn on the toggle button beside Bluetooth, then the button beside Automatically turn on tomorrow.
After you deactivate Bluetooth, it can now turn on by itself the next day. It probably tries to avoid interfering with your short-term preferences and believes you need it during your regular activity hours. As long as you aren’t actively using the linked device, it will drain the battery a little but not significantly. When no music is playing on the speaker or earphones you’re wearing, the connection remains in a low-power mode.

Android’s best-kept secrets

Every phone brand on Android has special features that are just waiting to be found, making it a labyrinth of capabilities. What you see on a Samsung may not be the same on a OnePlus or Pixel, and it’s precisely this diversity that adds excitement to the ecosystem. Digging behind those layers will reveal more hidden gems in productivity, privacy, accessibility, and multitasking.

10 settings you need to change to improve your Pixel experience

While Pixel phones offer many beneficial features by default, altering these specific settings can drastically affect The Google Pixel 9a could be the best-value phone of 2025, especially now that it has flagship-level AI capabilities, a dazzling 120Hz display, and a large battery at a more inexpensive price. However, like with every Pixel phone, the most useful functions are frequently disabled by default.

These suggestions are for a Pixel 9a running Android 15. The specific menu locations may differ slightly depending on the Pixel model and Android version you’re using, but the settings are broadly available throughout recent Pixel generations.Enhance your user experience.

Use smooth display

Pixels continue to ship with a dazzling Actua 120Hz OLED panel, which is set to a more cautious 60Hz by default. It’s fine for battery conservation, but if you prefer buttery-smooth scrolling and animations that showcase the screen’s full capability, enable Smooth Display.

Go to Settings > Display > Smooth Display and turn it on. You’ll notice an immediate improvement in responsiveness when scrolling through social networks or navigating the UI.

Use “At a Glance”

When you enable the Pixel’s smart widgets, the lock screen may transform into a small command center. At a Glance displays travel information, weather alerts, calendar events, and more.

All of this happens via the Pixel Launcher. Tap and hold any available space on the home screen, then pick Home settings, followed by the At a Glance settings button. There, you may control what kind of information display and what data sources it uses (with your permission, of course).

As an added bonus, the At a Glance widget on your home screen will display this information, increasing your chances of receiving notifications and updates.

Pixel 9 Pro with Gemini is the most powerful Pixel yet, and now comes in two sizes; it has a pro-level camera and it’s engineered by Google, so it gets the best of Google AI first
~~$999~~$799Amazon

Use caller ID and spam ID to save your time

Pixel phones actively filter out spam and unrecognized numbers. Google’s Caller ID and Spam feature detects robocalls and other unwanted calls before you answer.

Open the Phone app and navigate to Settings > Caller ID and Spam. Enable See caller and spam ID, and incoming calls will have a vivid red alert that cannot be ignored. If your Pixel has the option to filter spam calls, I recommend turning it on, as this prevents those calls from ringing your phone and instead sends them directly to voicemail.

Dismiss notifications across Pixel devices

This one is for the Pixel fanatics out there. If you have multiple Pixel devices signed in with the same Google account, you can sync notification dismissals between them.

Go to Settings > Notifications > Dismiss notifications from all Pixel devices. Toggle Dismiss on this device, grant notification access, and select the apps you wish to sync. Repeat the process on all of your Pixel devices to ensure that you never see the same notice twice.

Enable app suggestions on the home screen

The Pixel Launcher may provide app suggestions based on personal information such as location, time of day, and usage habits.

Tap and hold an available space on the home screen to access Home Settings > Suggestions. Enable Suggestions on Home Screen, then remove at least one static symbol from the bottom row of your Home Screen. That location will turn yellow and begin to change dynamically based on usage trends. You may even do this on the entire row if you like.

Increase battery life using Adaptive Battery and Extreme Saver.

Pixels already have a long battery life, but Google’s battery-saving features extend it much further. Adaptive Battery learns which apps you use the most and reduces power to the others. Extreme Battery Saver turns down non-essential apps to save power for days.

Enable both under Settings > Battery > Battery Saver > Adaptive Battery and Battery Saver > Extreme Battery Saver. You can also set schedules so that they activate automatically when needed.

Use Pixel Quick Tap feature

The Pixel’s Quick Tap function allows you to double-tap anywhere on the phone’s back to perform customized actions, but it is not activated by default. You can configure it to start the camera, take a screenshot, pause music, or open your preferred app.

Go to Settings > System > Gestures > Quick Tap, then enable it and select your chosen shortcut. Mine is set to toggle the flashlight, which is quite useful.

Enhance Now Playing on your lockscreen

Now Playing is a great tool that automatically recognizes songs that are playing around you. The phone displays that information on your lock screen in a passive manner. Even though the database is remarkable and entirely on-device, it cannot identify every song out there. This is where Google Search comes in.

Go to Settings > Display > Lock Screen > Now Playing and select Identify Songs Playing Nearby. Then, enable the Show search button on Lock Screen. The next time Now Playing fails, hit the lock screen icon to transmit the audio fingerprint to Google Search for a second viewpoint. It does not always work, but when it does, you will be glad you tried.

Change your lock screen privacy settings

By default, notifications appear on your lock screen, so others may view your messages. I always change this option on my new devices.

Go to Settings > Notifications and turn Sensitive notifications off. This keeps the sender and app visible while hiding the message contents. To ensure utmost privacy, go to Notifications on the lock screen and select Don’t show any notifications.

Make use of Live Translate and Interpreter Mode

Tensor-powered Pixels offer offline translation tools. Live Translate enables you to automatically translate text messages in real time.

Go to Settings > System > Live Translate, then Add a language. Depending on your choices, you’ll have access to services such as in-message translation, camera view translation, and live captioning for videos. Interpreter mode still requires Google Assistant, which is becoming less important now that Gemini has taken over.

How to uninstall system apps on Android (without root)
Unnecessary system apps and bloatware can be annoying. They drain your battery, take up important storage, operate in the background, and are frequently impossible to remove with standard methods. Although rooting your Android device gives you complete control over system programs, most users are not advised to do so because it violates your warranty and jeopardizes security.

Thankfully, there are secure and efficient methods for disabling or removing system programs without rooting, particularly when using ADB (Android Debug Bridge). We will go over every technique in this article, from basic settings adjustments to more sophisticated (yet secure) desktop tools.

What are system apps and why can’t you delete them easily

Applications that are pre-installed by the manufacturer or carrier of the device are known as system apps. These consist include third-party programs like Facebook or Netflix that OEMs package, stock utilities, or branded services.

They cannot be removed using the standard app menu since they are installed in the system partition. ADB commands, however, can be used to disable or even uninstall many.

Common examples of pre-installed system apps include:
- Duplicate media players or browsers
- OEM app stores
- Partner bloatware like Amazon Shopping, LinkedIn, or TikTok
- Preloaded games or theme services
Disable system apps from settings

This is the simplest method and doesn’t require a PC.

Steps:
1. Open Settings > Apps.
2. Tap See all apps to view the complete list.
3. Select the system app you want to disable.
4. Tap Disable. You may be asked to confirm your choice.
What happens when you disable an app:
- It is removed from the app drawer.
- It can no longer run in the background.
- It won’t receive updates or use system resources.
- The app is still stored on your device but rendered inactive.
Limitations:
- Not all system apps can be disabled (depends on OEM).
- Disabled apps can be re-enabled manually.
This is the safest approach for beginners.

Uninstall system apps using ADB (no root)

You can use ADB to perform advanced commands on your Android device by connecting it to a computer. This technique allows you to remove system programs for the current user without requiring root access.

Step 1: Set up ADB on your computer
1. Download the Android SDK Platform Tools for Windows, macOS, or Linux from Google’s official site.
2. Extract the contents to a folder (e.g., C:\adb).
Step 2: Enable developer options and USB debugging
1. Go to Settings > About phone.
2. Tap Build number 7 times until you see a message saying “You are now a developer.”
3. Go back to Settings > System > Developer options.
4. Enable USB debugging.
Step 3: Connect your phone to your PC
- Use a USB cable to connect your device.
- When prompted on your phone, allow USB debugging.
Step 4: Open ADB and check the connection
1. Open a terminal or command prompt in the ADB folder.
2. Type: adb devices – you should see your device listed.
Step 5: Find the package name of the app

To uninstall an app, you need its package name. You can find this using:
```
adb shell pm list packages | grep [app name]
```
For example, to find Facebook‘s package name:
```
adb shell pm list packages | grep facebook
```
Step 6: Uninstall the app

Use the following command:
```
adb shell pm uninstall --user 0 com.facebook.katana
```
That command will remove Facebook from your user profile, freeing up memory and removing it from the interface.

Note: The app is only removed for the current user, not deleted from the system partition.

Method 3: Use a no-root app debloater tool (GUI)

If you’re not comfortable with the command line, you can use a graphical tool like:
- Universal Android Debloater (UAD)
- ADB AppControl
- Android Debloater by XDA Developers
These tools allow you to:
- Browse installed system apps
- Uninstall or disable them safely
- See app names with friendly UI
- Restore apps if needed
Most tools require:
- ADB installed on your system
- USB debugging enabled
- Windows PC (some versions work with Linux/macOS)
They’re beginner-friendly and support a wide range of devices.

Should you uninstall or disable every system app?

No. Some system apps are critical to core Android functions. Removing them may cause:
- Boot loops
- Broken system features (e.g., notifications, calls, camera)
- Incompatibility with future updates
Always check what a system app does before removing it. You can research package names or use a debloater tool with built-in safety warnings.

Safe-to-remove examples:
- Social media bloatware
- OEM-specific cloud services you don’t use
- Built-in browser (if you use Chrome)
- AR apps, Game Launcher, or duplicate music players
Unsafe-to-remove examples:
- com.android.systemui
- com.google.android.gms
- com.android.providers.*
How to restore system apps uninstalled via ADB

If you want to bring back an app removed via ADB:
```
adb shell cmd package install-existing [package name]
```
For example:
```
adb shell cmd package install-existing com.facebook.katana
```
This will restore the app for the current user, assuming it wasn’t fully deleted from the system partition.

Uninstalling system apps without root gives you more control over your Android phone without compromising safety. ADB is a powerful tool that helps remove bloatware, reclaim storage, and speed up your device. If you’re cautious and avoid critical system packages, you can safely declutter your phone and enjoy a cleaner experience.

Whether you’re using the built-in disable function or running ADB commands, you don’t need root access to take control of your device anymore.

How to create secure folders on any Android device
Android users are particularly concerned about privacy and data safety, especially when saving sensitive files, images, or papers. Whether you are concerned about someone peeking through your gallery or want to protect business-related content, Android has built-in security features that do not require third-party apps.

This guide describes how to use secure folders and app-based file protection features on several Android devices, including Samsung, Google Pixel, and more.

What is a secure folder

A secure folder is a safe location on your Android smartphone where you can keep programs, files, and media separate from the main user interface. Access requires authentication (PIN, pattern, or fingerprint), ensuring that only you can open it. When data is moved to a safe folder, it is rendered invisible in conventional folders and apps such as Google Photos or File Manager.

Samsung’s Secure Folder is the best-known example, however other manufacturers provide comparable functionality.

How to use Secure Folder on Samsung Galaxy devices

Samsung offers a native solution called Secure Folder, available on most devices running One UI:
1. Enable Secure Folder:
  - Go to Settings > Security and privacy > Secure Folder.
  - Sign in to your Samsung account if prompted.
  - Set your preferred lock method (PIN, password, or biometric).
2. Add apps or files:
  - Open the Secure Folder app from your app drawer.
  - Tap Add apps to duplicate apps like Gallery, Notes, or Email.
  - Tap Add files to move photos, videos, or documents from regular storage.
3. Access and manage your folder:
  - Secure Folder functions as a sandbox. Files here do not interact with the rest of your phone.
  - Notifications from apps inside Secure Folder can be hidden.
  - You can even hide the Secure Folder icon for additional privacy.
Samsung’s Secure Folder is protected by Samsung Knox, ensuring hardware-based encryption.

How to create secure folders on Google Pixel (and stock Android)

Google Pixel and stock Android phones don’t include a “Secure Folder” app like Samsung, but there are still options:

1. Use Files by Google – Safe Folder

Files by Google includes a Safe Folder to protect sensitive files.
- Open the Files by Google app.
- Tap Browse, then scroll to Collections > Safe folder.
- Set up a 4-digit PIN when prompted.
- Move any files (photos, documents, videos) into the Safe Folder for encryption and restricted access.
Limitations:
- No secure app duplication.
- Cannot protect entire apps—only individual files.
2. Use screen pinning or app lock (if supported)

On Pixel phones, you can use screen pinning to lock a specific app:
- Go to Settings > Security > Advanced > Screen pinning.
- Turn it on and set it to ask for unlock credentials.
When enabled, you can lock an app to the screen and prevent switching until your PIN or fingerprint is entered.

Secure folder alternatives for OnePlus, Xiaomi, Vivo, and Realme

Many Android OEMs offer their own version of secure folder functionality:
- OnePlus (App Lock & Hidden Space):
  - Go to Settings > Utilities > App lock to lock apps.
  - Use Hidden Space (swipe right in the app drawer) to hide apps or files from plain view.
- Xiaomi (Second Space or App Lock):
  - Second Space lets you create a full-profile clone for private use.
  - App Lock in Settings lets you password-protect apps and media.
- Vivo/Realme:
  - Use File Safe or Private Safe under Security settings.
  - This lets you encrypt and store sensitive files securely.
Each of these tools serves a similar purpose: creating a private area for your data and apps that only you can access.

When should you use a secure folder

Secure folders are ideal for:
- Storing sensitive photos, work files, or legal documents
- Keeping personal messages or notes private
- Isolating apps with private data
- Creating a private profile for shared phones or kids
If your phone is shared, stolen, or accessed without your knowledge, a protected folder provides an additional layer of security.

Android provides numerous options to protect your most sensitive data, with secure folders ranking among the best built-in solutions for the purpose. Whether you use Samsung’s powerful Secure Folder, Google’s Safe Folder, or manufacturer-specific features, these solutions offer true privacy without the need to install third-party apps. To protect your digital life, ensure that they are correctly configured and that you use a strong authentication technique.

How to increase RAM using virtual memory (Android 13+)
Modern Android phones have powerful hardware, but even with high-end components, your handset may slow down while multitasking or gaming. To help with this, Android 13 added virtual RAM, sometimes known as “RAM Plus.” This function enables your device to use a portion of its internal storage as additional RAM, which improves performance in memory-intensive operations.

This guide explains what virtual memory is, how it works on Android 13+, and how to enable or adjust it.

What is virtual RAM and how does it work

Virtual RAM, also known as virtual memory or swap space, is a technology that allows some of your phone’s internal storage to be used as RAM. While this memory is slower than physical RAM, it allows the system to manage more background processes, keep apps open for longer periods of time, and minimize app reloads.

In Android 13, many manufacturers added a user-accessible option known as “RAM Plus” or “Memory Expansion.” This feature is particularly handy on phones with 4GB to 6GB of RAM, as multitasking frequently exceeds physical RAM limits.

How to check if your device supports RAM Plus

Not every Android smartphone supports RAM increase. It is up to the manufacturer to incorporate the capability in their version of Android 13 or later. Here is how to check:
1. Go to Settings.
2. Scroll down and tap Battery & device care or About phone (varies by brand).
3. Look for an option called RAM Plus, Memory Expansion, or similar.
4. If it’s available, you’ll be able to view and configure it from here.
Samsung, Xiaomi, Oppo, Realme, and Vivo are among the brands that offer this feature.

Enable RAM Plus on Samsung devices

Samsung phones running One UI 4.1 or later (based on Android 13) come with RAM Plus built-in. Here’s how to enable or adjust it:
1. Open the Settings app.
2. Scroll to Battery and device care.
3. Tap Memory.
4. Select RAM Plus.
5. Choose the amount of virtual RAM to allocate (2GB, 4GB, 6GB, or 8GB).
6. Restart your phone if prompted.
Samsung doesn’t let you disable RAM Plus entirely but allows you to choose the allocation size.

Enable virtual RAM on Xiaomi/Redmi/POCO phones

Devices with MIUI 13+ (Android 13-based) often support memory extension:
1. Open Settings.
2. Tap Additional settings.
3. Look for Memory Extension.
4. Toggle it on and allocate additional storage as virtual RAM.
5. Restart your phone for changes to take effect.
The memory extension size is usually fixed depending on the device—commonly 2GB or 3GB.

Enable virtual RAM on Realme, Oppo, and Vivo devices

These brands typically offer memory expansion as well:
- Realme UI/ColorOS:
  1. Open Settings.
  2. Tap About Phone > RAM.
  3. Enable RAM Expansion and select a size.
  4. Restart when prompted.
- Vivo Funtouch OS:
  1. Open Settings.
  2. Tap RAM and storage space.
  3. Tap RAM Expansion.
  4. Turn on and choose the RAM boost size.
If you can’t find this feature, ensure your phone is running the latest version of Android 13 or consult the manufacturer’s support site.

Does virtual RAM actually improve performance

Virtual RAM helps in specific scenarios, especially on phones with less physical RAM (4GB or 6GB). Benefits include:
- Reduced app reloads
- Smoother multitasking
- Better background app retention
- Less lag during memory-heavy tasks
However, it will not transform an affordable phone into a premium gadget. Because internal storage is slower than actual RAM, the benefit is minimal yet visible during heavy multitasking.

How much virtual RAM should you use

The best setting depends on your device’s internal storage space and usage pattern:
- If your phone has at least 128GB of storage and you multitask often, you can allocate 4GB–6GB.
- If your storage is nearly full, avoid setting high values to prevent system lag.
- On 64GB devices, 2GB–3GB is usually safe.
You can experiment to determine what works best, but keep some open storage space to avoid overall slowdowns.

Virtual RAM is an excellent technique to increase your phone’s memory capacity without updating the hardware. While it is not a miracle cure, allowing RAM expansion can boost your Android device’s performance and multitasking abilities. If your phone supports it, give it a shot—just do not use up all of your storage space.

How to change the default apps on new Android devices
You have complete control over the default apps you use on Android for email, calls, texts, browsing, and more. Android lets you select your favorite apps as defaults, whether it be Chrome or Firefox, Gmail or Outlook, or any other third-party software that is compatible, in contrast to other mobile operating systems that force you to use a limited number of apps.

We will show you how to change the default Android apps in this tutorial. We will go over how it functions on both stock Android and well-known manufacturer skins, such as Xiaomi’s MIUI and Samsung’s One UI, as well as what to do in situations when Android lacks a default app option.

Why change your default apps?

Changing your default apps can increase productivity and improve your experience. For instance, you may wish to use:
- A privacy-focused browser like DuckDuckGo instead of Chrome
- A lightweight email app instead of the default one
- A better gallery app with cloud backup support
- A different SMS app with customization features
Once set, Android uses your selected app automatically — no need to choose each time.

What types of default apps can be changed?

Android supports default app selection for a variety of functions, including:
- Browser (e.g., Chrome, Firefox, Brave)
- Phone (dialer apps)
- Messaging/SMS (e.g., Google Messages, Textra)
- Email (e.g., Gmail, Outlook, K-9 Mail)
- Home screen launcher
- Digital assistant
- Camera
- Gallery/photos
- Music player
- Navigation apps (Maps, Waze, etc.)
- Links handling (web, YouTube, etc.)
Some apps will request to be the default when first installed or opened but you can always change this manually.

How to change default apps on stock Android

Here’s how to manage your default apps on phones running near-stock Android (such as Pixel, Motorola, or Nokia devices):
1. Open the Settings app.
2. Tap on Apps.
3. Choose Default apps.
4. You’ll see a list of categories: browser app, phone app, SMS app, assistant app, home app, etc.
5. Tap any category to see installed apps compatible with that function.
6. Choose your preferred app from the list.
Android will immediately make the chosen app the activity’s default. If you change the browser’s default, for instance, any link you click will open in the selected browser.

How to change default apps on Samsung (One UI)

Samsung devices with One UI take a somewhat different path:
1. Go to Settings.
2. Tap on Apps.
3. Tap the three dots in the top-right corner and select Default apps.
4. You’ll see the same categories as stock Android: browser, calling, messaging, and more.
5. Tap the category you want to change.
6. Select your new default app.
Samsung devices also let you reset all default apps at once via Settings > Apps > Three dots > Reset app preferences.

How to change default apps on Xiaomi (MIUI)

MIUI includes a “Manage apps” section to control default apps:
1. Open the Settings app.
2. Go to Apps > Manage apps.
3. Tap the three dots in the top-right and select Default apps.
4. Choose a category like browser, dialer, messaging, or gallery.
5. Select your desired app.
MIUI might ask you to select a new default app after installation or when you attempt to open related content.

How to handle app-specific defaults (like file types or links)

Some apps don’t appear in the general default app settings but can still be set as defaults when opening certain file types or links.

To manage these:
1. Go to Settings > Apps.
2. Tap See all apps and choose the app you want to configure.
3. Tap Open by default.
4. Enable Open supported links or clear defaults by tapping Clear defaults.
This is useful if you want all YouTube links to open in the app rather than in a browser, or if you have accidentally enabled an app to always open PDFs or photos.

How to reset default apps

If you’ve set the wrong default app or want to start over:
1. Open Settings > Apps.
2. Tap the three dots (or menu icon).
3. Select Reset app preferences.
4. Confirm to reset all app defaults.
This won’t delete any data but will clear app defaults, disabled apps, and permission restrictions.

Alternatively, to reset just one app:
- Go to Settings > Apps > [App Name] > Open by default
- Tap Clear defaults
This lets you reassign that app’s function later.

Choosing the best default apps

Here are some recommended apps to consider setting as default:
- Browser: Firefox Focus (privacy), Brave (ad blocking), Chrome (sync)
- Email: Gmail (Google integration), Outlook (work email), BlueMail (multi-account)
- Messaging: Signal (privacy), Google Messages (RCS), Textra (customizable)
- Gallery: Simple Gallery, Google Photos, Aves
- Music: YouTube Music, VLC, Poweramp
- Navigation: Google Maps, Waze, HERE WeGo
Make sure the app supports being set as a default. Some lightweight or older apps may not offer this functionality.

What if Android won’t let you change a default?

Some Android versions or manufacturers may restrict default app changes for certain functions — especially camera or dialer apps. In those cases:
- Make sure the new app is fully updated and has the necessary permissions.
- Check for manufacturer limitations in forums.
- Use Activity Launcher or ADB commands (for advanced users) to override.
- Root access may be required for some deep changes — though this is not recommended for most users.
Changing the default apps on Android provides you control over your digital experience. Whether you want a speedier browser, a cleaner messaging app, or a more powerful camera, Android allows you to select what works best for you.

By looking into your device’s default app settings, you may optimize your workflows and eliminate annoyances such as accessing links in the wrong app or using services you dislike. With a few touches, Android becomes your own—not what the manufacturer or carrier wants you to use.
