The phone app (white receiver, green background) shows a red badge with the count of "-1" after every use of the app. I don't even have app icon badges enabled for the app. Restarting the phone clears the "-1" count but only until the next use of the app.

AndrewL, thanks for your reply. However, when I hold down the power button, I do not get a logo. I get three options: Power off, Restart, and Emergency mode/ Off. Should I select Restart? Thanks
