You sound like android triage team.

Apk provided can be installed on an attackers phone, you specify the msisdn (phone number) of victims phone, click send and it crashes telephony app of the victim.

Multiple messages may create a race condition that corrupts an SQLite database that stores message which stops telephony from functioning as a phone. WiFi will still work so I guess you can use it as a tablet as long as you don’t mind the constant dialogs popping up.

Tested in AU, US, DE and UK with 100% success rate.
