Allows read only access to phone state, including the current cellular network information, the status of any ongoing calls, and a list of any PhoneAccounts registered on the device.
This is used to interfere with incoming phone calls. No personal data is accessed.

Marker permission for applications that wish to access notification policy.
This allows the app to change the DoNotDisturb mode. No personal data is accessed or stored.
