Allows the app to access the phone features of the device. This permission allows the app to determine the phone number and device IDs, whether a call is active, and the remote number connected by a call.

Allows the app to disable the keylock and any associated password security. For example, the phone disables the keylock when receiving an incoming phone call, then re-enables the keylock when the call is finished.

Allows the app to create network sockets and use custom network protocols. The browser and other applications provide means to send data to the internet, so this permission is not required to send data to the internet.

Allows the app to have itself started as soon as the system has finished booting. This can make it take longer to start the device and allow the app to slow down the overall device by always running.

Allows the app to view the configuration of Bluetooth on the device, and to make and accept connections with paired devices.
