Hello! I have an iPhone 6s with gray vertical lines in the display (touch not working). I first thought the screen was damaged and tried a new screen on it, but the lines still appear. I thought the Ic touch could be damaged, but I find out is no longer in the motherboard. Any suggestions of what the issues could be?
Yeah the touch IC chip is located on the screen and not the logic board this time unlike the iPhone 6(non S) and 6+. If the phone still has warranty you should contact apple to get it replaced.
