Allows read only access to phone state, including the current cellular network information, the status of any ongoing calls, and a list of any android.telecom.PhoneAccount registered on the device. Note: If both your ' minSdkVersion and ' targetSdkVersion values are set to 3 or lower, the system implicitly grants your app this permission. If you don't need this permission, be sure your ' targetSdkVersion is 4 or higher.
Allows an application to receive the ACTION_BOOT_COMPLETED that is broadcast after the system finishes booting. If you don't request this permission, you will not receive the broadcast at that time. Though holding this permission does not have any security implications, it can have a negative impact on the user experience by increasing the amount of time it takes the system to start and allowing applications to have themselves running without the user being aware of them. As such, you must explicitly declare your use of this facility to make that visible to the user.
