Black screen
When I open CAMERA app on my iPhone 8 , iOS 11.4.1 after I turn on the selfie camera I can’t take photoes the I saw is black screen and I can’t do anything. I reset all setting, I restart prone and nothing. In everyone app where I have option for camera like Instagram, Snapchat I can’t turn selfie cam, when I have video chat i can use only backup cam. What I have to do to fix the problem?
