My display popped out and now not working just lights up a little
my iPhone 6 had a broken screen for a while but everything was working so I was living with it, until a few days back when I dropped it again and now the whole screen popped out. I immediately pushed it back, pressed the home button and the screen didn't show anything but it lit up a bit so it wasn't completely black. The phone is still on because I keep charging it and sometimes when press the home button there are two thin(vertical) white lines in the middle. Is there any way how can I find out if the problem is in motherboard or if it's just screen issue?
Is this a good question?
