Enable WRITE_SMS for telephony provider
WRITE_SMS app op is explicitly granted to some system components like bluetooh, phone, mms service. It is however no granted to the telephony provider. The latter is the one storing the SMS data and should always have the app op enabled. Content providers perform proxy app op updates (taking a note they perform an operation on behalf of another app) which requires the proxy package, the provider, to have the app op allowed. bug:23017449 Change-Id: Ic0c6865a616b6f3997a64d390699e9fd86c4ae2e
