How Can I Remove CA Certificate From Android Phones

There are some apps I enjoy using that are not available on the Play Store. The Play Store does not allow any apps that are banned from the store. There is no Play Store for these types of apps, but they can be downloaded directly from the apps’ website. One of them is Adaway which is a open source adblocker for Android to block apps from Android in showing advertisements.

It has its own website and users can download and use it. It installs one certificate which is a CA certificate. It monitors traffic through these certificate installation and host file and when you uninstall Adaway from Android, it will simply uninstall from app but its certificates not be uninstalled through it. This means even if you uninstall it , will continuosly monitor yours device androuid traffic inflow.
