    How to block ads on Android without root (2025 guide)

    Online ads can be annoying, whether you are watching YouTube, perusing a news website, or using a free software. Aside from being unpleasant, they can slow down your device, use bandwidth, and compromise your privacy. Fortunately, you can disable most advertising on Android without rooting your device or installing costly apps. This comprehensive guide describes the best ways to block advertisements on websites, applications, and games using free and secure techniques.

    Why should you block ads on your device?

    Blocking ads on your Android phone does more than merely improve the user experience. There are practical advantages that improve device performance, privacy, and security. Here’s why many users prefer to block advertisements:

    1. Improved Performance

    Ads frequently load media-rich material such as photos, animations, and videos, which eat memory and CPU cycles. On smartphones with limited resources, this might result in slower loading times, slowness, and even app crashes. Blocking advertisements frees up system resources and improves program responsiveness.

    2. Better Battery Life

    Since many ads are dynamic and constantly update, they continue running in the background, which drains the battery. Blocking these elements can significantly extend battery life, especially on older devices.

    3. Reduced Data Usage

    When an ad loads, it consumes bandwidth. For individuals with limited data plans, this may result in higher mobile bills or throttling. Blocking advertising helps you save your monthly data allowance.

    4. Enhanced Privacy and Security

    Ads sometimes include tracking scripts that track your activity across apps and websites. Malicious advertising (malvertising) can occasionally lead consumers to phishing or malware-infected websites. Blocking advertisements reduces the likelihood of tracking and exposure to hazardous content.

    Block ads in browsers with Brave or Firefox + uBlock Origin

    Use Brave browser with built-In ad blocking

    The Brave browser prioritizes privacy and includes built-in ad and tracker blocking. Unlike Chrome, which does not enable ad-blocking, Brave automatically removes the majority of advertisements and tracking scripts from websites.

    How to use Brave:

    1. Go to the Google Play Store and install Brave Browser.
    2. Open the app and begin browsing — ad blocking is enabled by default.
    3. To customize settings, go to Brave’s menu > Settings > Shields. You can adjust how strictly ads and trackers are blocked.

    Brave also provides other settings such as script blocking, cookie control, and HTTPS upgrades to improve your surfing privacy even further.

    Best Use Case: Blocking ads on most websites instantly, without needing any extensions or additional configuration.

    Use Firefox with the uBlock Origin Add-On

    If you prefer Firefox, it provides a more personalized experience by supporting third-party add-ons such as uBlock Origin, one of the most powerful ad blocks accessible.

    Steps to set up uBlock Origin on Firefox:

    1. Install the latest version of Firefox for Android.
    2. Visit addons.mozilla.org from within the browser.
    3. Search for “uBlock Origin” and add it to Firefox.
    4. Once installed, uBlock Origin will immediately begin filtering ads on websites.

    You may set up custom filters, activate regional ad lists, and block certain aspects on a webpage. This level of control makes Firefox with uBlock Origin excellent for users seeking extensive filtering options.

    Best Use Case: Users who want granular control over what gets blocked and which filters are applied.

    Use private DNS to block ads system-wide (Android 9+)

    android private dns for ad block

    Since Android 9 (Pie), users can use a feature known as Private DNS. It connects you to a DNS provider, which filters out known ad-serving domains before they load, essentially blocking advertisements in all browsers and many apps.

    Steps to enable Private DNS:

    1. Open Settings on your phone.
    2. Navigate to Network & Internet > Private DNS.
    3. Select “Private DNS provider hostname”
    4. Enter the hostname of a DNS provider that supports ad blocking.
    5. Save the changes.

    Popular Ad-Blocking DNS Providers:

    ProviderHostnameDescription
    AdGuard DNSdns.adguard.comBlocks most ads and trackers
    NextDNSdns.nextdns.io/your-config-idHighly customizable with user-defined filters
    Control D Freefreedns.controld.comOffers ad/tracker filtering without an account

    Advantages:

    • Blocks ads across apps, not just in browsers
    • Doesn’t require any apps or root access
    • Improves loading speeds and reduces unwanted traffic

    Limitations:

    • May not block all in-app ads or YouTube ads
    • Some mobile networks may not support encrypted DNS

    Best Use Case: Non-root system-wide ad blocking with minimal setup effort.

    Use AdGuard content blocker for supported browsers

    AdGuard content blocker block ads on Android

    The AdGuard Content Blocker is a free application that disables advertisements in browsers such as Samsung Internet and Yandex Browser without having root access.

    How to install and use AdGuard Content Blocker:

    1. Download the app from the official AdGuard website or from F-Droid.
    2. Open the app and select the browser you use (Samsung Internet or Yandex).
    3. Enable content filters like EasyList or AdGuard Base Filter.
    4. Ads will be blocked while browsing within the supported browser.

    Advantages:

    • Offers control over what filters are applied
    • Requires no permissions or rooting
    • Supports multiple languages and filter lists

    Limitations:

    • Does not block ads inside other apps
    • Only works with supported browsers (not Chrome)

    Best Use Case: Samsung or Yandex browser users seeking browser-specific ad blocking without full system-wide solutions.

    Use a custom hosts file or DNS66 (No Root Required)

    Tech-savvy users may prefer to utilize a custom hosts file that redirects known ad-serving domains to a blank IP address. DNS66, for example, provides this capabilities without the need for root access.

    How it works:

    • DNS66 creates a local VPN tunnel and uses a custom hosts file.
    • Any requests to known ad servers are blocked at the DNS level.
    • It filters traffic system-wide, including ads in apps and games.

    Steps to use DNS66:

    1. Download DNS66 from F-Droid (it’s not available on the Play Store).
    2. Launch the app and configure which hosts files to use (e.g., AdAway or Energized).
    3. Start the VPN service and allow the app to block domains across the system.

    Best Use Case: Advanced users who want fine-tuned control over DNS-level ad blocking without root.

    Note: Since DNS66 uses a local VPN, you cannot run other VPNs at the same time.

    What about YouTube ads?

    YouTube uses server-side ad distribution, which makes it difficult to prevent adverts in the official YouTube app. However, there are various workarounds available:

    youtube ads

    Option 1: watch YouTube in Brave or Firefox with Ad Blocking

    • Open YouTube.com in Brave or Firefox with uBlock Origin enabled.
    • Ads will be stripped from videos on the web interface.
    • You can even use picture-in-picture mode on supported devices.

    Option 2: Use YouTube Vanced or ReVanced

    YouTube Vanced (now discontinued) and its successor, ReVanced, offer modified YouTube apps with built-in ad-blocking and background playback.

    Important Notes:

    • These apps must be sideloaded and are not available on the Play Store.
    • Use trusted sources such as GitHub or community forums to avoid malware.
    • YouTube may update its API to block these apps in the future.

    Best Use Case: Users who regularly watch YouTube and want a consistent ad-free experience without paying for YouTube Premium.

    Additional tips to reduce ads and trackers on Android devices

    If you want even more control over your privacy and device experience, consider these extra steps:

    • Use a privacy-focused VPN with built-in ad and malware blocking (e.g., Proton VPN, NordVPN, Surfshark).
    • Enable Data Saver or Lite Mode in Chrome to minimize ad-heavy content.
    • Regularly clear app cache and browsing data to remove trackers.
    • Turn off personalized ads by visiting Google Ad Settings and disabling ad personalization.

    Final Thoughts

    Blocking ads on Android no longer necessitates technical knowledge or rooting the device. The majority of advertisements may be removed from your browsing and app experience using browser-based blockers, DNS-based filtering, and content-blocking applications.

    These methods are safe, effective, and frequently free. Whether you are concerned about performance, data use, or privacy, using these ad-blocking tactics will significantly enhance your Android experience.

  • How to block trackers in DuckDuckGo Android app

    How to block trackers in DuckDuckGo Android app

    The “App Tracking Protection” feature of DuckDuckGo for Android has entered open beta and now enables all Android users to prevent third-party trackers across all of their installed apps.

    The DuckDuckGo for Android app is a privacy-focused web browser, search engine, and data protection utility, downloaded over 10 million times from Google Play. It includes numerous privacy features, including search term anonymity, hidden tracker blocking, email tracker protection, auto-HTTPS, and one-tap browsing history clearing.

    By preventing third-party tracking scripts in other Android apps that have been installed on the device, the “App Tracking Protection” attempts to increase privacy throughout the entire operating system.

    ‘It’s a free feature in the DuckDuckGo Android app that helps block 3rd party trackers in the apps on your phone (like Google spying in your weather app),’ stated DuckDuckGo today. ‘This means more comprehensive privacy and less invasive targeting.

    The new version of App Tracking Protection allows Android users to see precisely which trackers are blocked and what kind of data they are seeking, in contrast to the prior close beta version of the service.

    The feature is somewhat similar to Apple’s ‘App Tracking Transparency,’ but unlike the Apple feature, DuckDuckGo’s system does not depend on the app developers’ compliance with user choice.

    Blocking all known trackers

    According to DuckDuckGo, Android users have 35 apps installed on their smartphones on average, which results in 1,000–2,000 daily tracking attempts for more than 70 tracking organizations.

    While consumers frequently use their devices to browse the web, play games, or check the weather, the App Tracking Protection guarantees to thwart all these attempts in the background.

    Additionally, this blocking occurs with no discernible impact on device performance, which was enhanced in the most recent version of the app.

    The blocking is based on a constantly updated and growing list of known trackers and is independent of the user’s choice in the associated tracking request dialogs usually served within apps.

    To activate the new feature, the user has to open the DuckDuckGo app on Android, navigate to Settings → More from DuckDuckGo, and then enable App Tracking Protection, as shown below.

    duckduckgo
    Activating App Tracking Protection

    The function operates by setting up the DuckDuckGo for Android app on the device as a VPN, enabling the app to filter app traffic and block trackers.

    However, unlike a conventional VPN, this is only used locally and does not offer anonymity when using the internet or connecting to other remote devices.

    “App Tracking Protection uses a local “VPN connection,” which means that it works its magic right on your smartphone and without sending app data to DuckDuckGo or other remote servers,” explains DuckDuckGo.

    summary

    Therefore, to enable the feature, DuckDuckGo will request the user allow the VPN connection to be created, which is required for the blocker to function as expected.

    From then on, the app will regularly update the user with automatically generated summaries of blocked app trackers to give them an idea of what is happening behind the scenes.

    Those who want to evaluate how threatening each app is to their privacy can use App Tracking Protection’s real-time view to see what trackers are loaded and blocked.

    Although App Tracking Protection is a strong tool, users should be aware that it is still in the beta testing phase of development.

    Info report

    As a result, it could result in performance issues, incorrect operation of websites or apps, or the evasion of some trackers. You can turn off the feature if you experience any of these problems.
