iPhone 6 Black Screen but it's on & can still receive calls
This is the first time I have experienced with my Iphone 6. After I charged it, when I was answering e-mails the screen turned black. I was thinking maybe it was the battery. But when I try to charge it again the screen is still black and I got surprised that my Iphone is ringing and I can still answer calls and it alarms and I still receive text messages. But I couldn't open it because the screen display is black. I tried to "hard reset" but It did not work. What could be the problem? I did not drop the iphone. The screen just turned black unexpectedly.
