IPHONE XR BLACK SCREEN OF DEATH
So the other day, I was chatting on WhatsApp and then my XR suddenly froze and slowly went black. I tried not to panic, I waited for the phone to cool down cos it was kinda hot. Bear in mind that this phone wasn’t dropped in water or on the ground, it just “poof” and went black! When it cooled down, I rebooted it and plugged it in, it responded to it being plugged in and other notifications came in but the screen was still pitch black! I can even FaceTime friends with the help of Siri and they will be able to see me but I can’t see them or anything on my screen. I’ve tried everything I’ve seen online from powering on and off to hard resetting yet no avail. My trusted friend who fixes iPhones doesn’t even know how to fix it. Please what do I do?
