Razão pela qual os privilégios ROOT não estão totalmente desabilitados no firmware Android (firmware personalizável):
Nosso firmware padrão é compilado em modo de depuração, permitindo que o software obtenha certos privilégios de root do sistema. 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.
