Ads-Block using Private DNS: [No Root] [Android 9.0 Pie]
Written by Hassan Abbas

Ads-Block using Private DNS: Google launched different new features with Android 9 Pie. These features include an adaptive battery, adaptive brightness, app actions, and much more. However, there is one specific feature, called Private DNS a.k.a DNS over TLS. We think that it is one of the most underrated features of Android 9 Pie. With DNS over TLS, you can change or connect to a different DNS on your Android phones easily. In our guide, we will use the Adguard DNS to block ads and popups on your Android devices natively.

How does Adguard DNS work?

Adguard is one of the most popular AdBlocking tools that are available across platforms. It is available for Windows, Android, Linux, and more. Here in this guide, we will show you how to make use of Adguard DNS to keep your device safe from unnecessary ads, popups, and more. So after setting up all your queries will be sent to the specific DNS and it will filter out any or all the ads and popups from the source. This is similar to how Adblock browser extensions work.

The major reason for using this feature is that you get rootless systemwide ad-blocking on your Android devices. Meaning, once you set up, all your apps, and browsers will be clean from ads and be served under adblockers. Unfortunately, you cannot change the host’s files. Meaning, you cannot choose the URLs you want to block.

Generally, to block ads on Android, your device either need to be rooted or use a VPN like a Blockade too. But we all know how VPN certainly be memory hogging and a battery drainer. So this is the best solution.
