How to block ads on Android phones using Private DNS and apps

Ads on Android phones and tablets have become increasingly intrusive, particularly in free apps and games. Many users report frequent full screen ads and limited control while navigating apps.

Android offers system level and app based options to reduce or block ads. These methods work on most phones and tablets running recent Android versions.

Block ads using Private DNS

One of the easiest ways to block ads on Android is by setting up a private DNS. This feature was introduced with Android 9 Pie in 2018 and works at the system level.

To enable it, users need to open the Settings app and search for DNS. Select Private DNS provider hostname or Specified DNS, depending on the device brand. Enter dns.adguard.com and tap Save.

Once enabled, most ads and pop up banners across apps and browsers are blocked. Some websites may not load correctly after this change. Users can disable private DNS if they face access issues. Several alternative DNS providers are also available.

Block ads using AdAway or Blokada

AdAway has long been used by Android users to block ads. The app now supports both rooted and non rooted devices. On rooted phones, it modifies the system host file to block ad serving domains. On non rooted devices, it uses a local VPN to filter ads in apps and browsers.

AdAway is open source and free to use. It can be downloaded from GitHub.

Blokada is another popular alternative. It functions similarly by blocking ad domains through a local VPN. The app also offers DNS encryption and allows users to manage blocked and whitelisted domains.

These tools provide additional control for users who want more advanced ad blocking beyond system settings.
