Superuser Usage

Grant and manage Superuser rights for your phone. This app requires that you already have root, or a custom recovery image to work.

Note: The app and binary will have different versions. The app is updated more often than the binary is.

Superuser cannot be uninstalled if it was installed with your ROM or root. If there is no uninstall option, it’s because you placed it in /system/app. It is impossible for an app to be installed in /system/app by the Google Play store. In fact, the entire /system partition is read only at runtime. The only way for an app to be placed in /system/app is via a rooting process (which usually installs Superuser), or by remounting the system partition as read/write and manually putting it there.

The following permissions are requested by this app:

1. Internet: for updating the binary.
2. External storage: for backup/restore for elite users.
3. NFC: for creating an allow tag for elite users.
4. Boot completed: for fixing database on boot.

The developer of this app does not offer any support.
