PhoneAccount Abuse Detector is a simple application to enumerate and detect any application that (ab)uses adding an indefinite amount of PhoneAccount(s) to Android's TelecomManager.

This application exists because malicious or just improperly programmed applications can, intentionally or not, block your device from the ability to call emergency numbers. If you are in such a situation, this app helps you to find the culprit – which you then can uninstall (or disable).
