Superuser is the term used to authorize that a normal user can act as a super user (sudo -> super user do) so that any normal user can freely “mastering system“.
Rooting your phone gives you total control. Superuser application is installed after rooting your Android. This application can only work if your Android already have root.
So why have super user if any user with easy control of the system? This is not contrary to the security problems? For example: a normal user can be SU then he can change himself the configuration of the system according to the user wishes.
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
Support request emails that simply say “Doesn’t work” or something to that effect are automatically deleted by our stupidity filter and will not be answered.
