iPhone 7 gets stuck at Call screen. How to fix this?
iPhone 7 (128 GB, Black, India)
Running iOS 10.1.1
My recently bought iPhone 7 gets stuck on the call screen. No ringing sound, no sound from the person on the other side of the call. Home Buttons, as well as Lock Screen Buttons, becomes ineffective. I have to wait till the person on the other end hangs up. That's the only way to get back to normal. Same thing keeps on happening until I restart the phone. This is very annoying. Any way to fix this?
