Hello charlene275,

1. Restart your device
   • Hold the On/Off button until "slide to power off" appears. Slide to power off your device. When it is off, press the On/Off button to turn it back on.
   • If you can't restart your device, reset it by pressing and holding the Sleep/Wake button and the Home button at the same time for a least ten seconds, until the Apple logo appears.
2. Clean the screen with a soft, slightly damp, lint-free cloth.
3. Avoid using the device while wearing gloves, with wet hands, or immediately after applying hand lotion.
4. If you have a protective case, or if you are using a plastic sheet or film on the display, try removing them and testing the device without it.

Best of luck,

Mario
