iPhone XR screen
I went to sleep last night and my screen was perfectly fine and I woke up and it was in the same spot but the screen doesn’t work, I press the power button to turn it on and all it shows is a grey screen, it won’t let me power it off or answer calls. I receive calls and notifications and Siri works but I cannot see the screen whatsoever nor will it let me tap anything. How do I fix this issue?
