Phone app badge showing "-1"
After receiving an unanswered call, the phone app badge has been displaying a "-1", the recent/missed call logs were erased and the logs are no longer recording any calls. Regardless of the call coming in, the badge still reads "-1" and never changes, however, the Contacts list is still intact, and the Keypad and Voicemail still function normally.
I've tried all of the following to fix the issue to no avail:
- reboot
- force restart
- install latest update
- reset network settings
- remove and clean SIM card
I have yet to try Reset All Settings to factory settings but will most likely do that next unless someone has any other ideas of how to fix the issue otherwise.
