The description of SuperUser Apk
SuperUser is the special for after rooting your device, you need an apk installed on your device to manage for applications on 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.
