The screen goes black once I place a phone call. Even in calling myself and not answering the call, I had to restart my phone in order to get back control of it. I never picked up the call from the other end.
In retrospect, I wonder if control would have been restored to my phone if I picked up the other phone and hung it up. I turned off features like WiFi Calling, but I still have this issue.
What could be the problem and how do I solve it? Thanks in advance for your support!
