Acerca de la función ROOT del firmware de Android

Reason why ROOT privileges are not fully disabled in the Android firmware (customizable firmware):
Our standard firmware is compiled in debug mode, allowing the software to obtain certain system root privileges. It is not possible to disable all root privileges via the reserved switch in the settings.
To fully disable root privileges, the firmware must be compiled in user mode.In this mode, apps can only obtain partial permissions after requesting authorization,and some special system permissions are also disabled, which may prevent apps from accessing certain special functions.
If complete root permission disablement is required, a custom dedicated firmware must be developed, which is supported as a customizable option.
