So I have had my iPhone 5s for almost a year now and I have never had any really weird or strange issues like this. So tonight I was on Facebook on my phone and then all the sudden I get vertical stripes. I start panicking because I have/had no clue on whats going on. After a while I got the stripes to go away, but now I can get my phone to go to apple that it shows when its starting up, but then the phone goes to a grey screen and it will continue to do that. My phone at the time was a little hot, but at the tie that I'm typing this it's back to it's normal cold self. It's at 100% battery and won't turn on even with the charger plugged into it. Can someone please tell what to do or how can I get my phone fixed without loosing everything that's on my phone?
Note: If I push on the bottom part of my screen above the home button it makes a pop sound. I'm pretty sure my screen is coming off. But still I would like some help because this is making me sick to my stomach.
