White Vertical Lines on Screen
Help me? My iPhone 5S suddenly turns off and goes on a reboot loop on the logo screen then after the third loop, it frequently have the green and pink lines until it turns white. Sometimes I get the full white screen.
I tried hard resetting it, software restore and even replaced the battery, though not from the official Apple Store because I have to go to a 2-3 hours trip to where there are Apple Stores so I just went to local malls.
I don't think I have dropped the phone or anything but it gets triggered when I open certain apps and the phone slowly heats up.
Can sombody give me a solution or advice? Please and thank you.
