“My birthday gift was an iPhone from my boyfriend. Last week he installed iOS 11 and the phone now has flickering horizontal lines across the screen. He factory reset the phone and re-installed the iOS 11, but it still didn’t work. My iPhone screen is flickering. He contacted Apple support and the technicians told him the device is having problems with the new iOS. But this was a new issue to them, they will not replace the phone since it is not under their guarantee. So I now own a useless phone, why is my iPhone 6 screen flickering, any clue?”
“My iPhone 4 started to freeze out of blue, open apps on its own at random, scrolling pages, and the screen flickers. I’m sure I’ve never dropped it to water or soaked it in any other liquids. Why does my iPhone screen flicker? Can anyone help me fix it?”
