android: handle ConnectionService failures more resiliently

Some Samsung devices will fail to fully engage ConnectionService if no SIM card
was ever installed on the device. We could check for it, but it would require
the CALL_PHONE permission, which is not something we want to do, so fallback to
not using ConnectionService.
