AdGuard Content Blocker does not require root access. It can be installed and run on any Android device — no need to go through the long, tiresome, and sometimes even dangerous process of rooting your phone or tablet.
The app is free and, as per our company policy, it is open source. On GitHub you can not only see the source code, but also ask any questions and get answers directly from the developers.
No. Google's policy doesn't allow any system-level ad blockers inside the Google Play Store, only content blockers. They are fine at blocking ads in a specific browser, but they lack flexibility and have significantly fewer tools at their disposal. The primary AdGuard for Android app is much more functional and can block ads in all browsers and even in other apps.
It is totally up to you! We offer a lot of filters to choose from, both our own and third-party filters. We recommend you to keep the AdGuard Base filter enabled at all times, and language-specific filters can also be extremely helpful depending on your native language.
At the moment, only two browsers support the content blocking technology: Samsung Internet and Yandex.Browser. Once more browsers join their ranks, the area of application for AdGuard Content Blocker will increase.
