iphone 11pro locked up after using Facetime
I have a iphone 11 pro.
I called my wife using facetime to have a visual conversation but She picked up using her cars steering wheel controls so there was only an audible conversation then she hung up. since that time I cant open any apps on the screen, use the RHS button, cant reboot.
I can delete apps and appears I can open facetime but screen is cloudy grey (as if its opened but nothing on screen)
deleted FT and FB but still no operation of the screen apps or the RHS button?
Any suggestions ? I want to avoid doing a hard reboot if possible.
Regards
