Super User Download 3.1.3
rant and manage Superuser rights for your phone.
This app requires that you already have root, or a custom recovery image to work.
Note: App and binary will have different versions. The app is updated more often than the binary is.
This app 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, not me. It is impossible for an app to be installed in /system/app by the 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.
Permissions requested are for:
Internet - updating the binary
External storage - backup/restore for elite users
NFC - creating an allow tag for elite users
Boot completed - fix database on boot
