Vertical lines on iPhone 6 screen
My son's iPhone 6 screen has three thin vertical lines on it. What could be the cause for this and how can we fix it?
iPhone 6, iOS 8.1.2
First try a reset. Press and hold both the Home button and the Sleep/Wake button continuously until the Apple logo appears. Then release the button and let the device restart. You will not lose data doing this. It's like a computer reboot.
If that doesn't help the problem is most likely cause by a hardware problem in the screen. Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support. Be sure to back up your device before taking or sending it to Apple.
