Your iPhone or iPod touch may experience one of the following symptoms:
- Multi-Touch display (or touchscreen) does not respond
- Portions of the Multi-Touch display do not respond
- Multi-Touch display is very slow to respond
If your device is experiencing any of the symptoms listed above, try the following steps:
- Clean the iPhone screen with a soft, slightly damp, lint-free cloth.
- Do not wear gloves while using the Multi-Touch display. Do not use the touchscreen with wet hands or immediately after applying hand lotion. Moisture affects touchscreen behavior in the same manner as it affects a trackpad.
- If you have a protective plastic sheet or film on the touchscreen, try removing it. It may be preventing the touchscreen from working properly.
- If that doesn't work, turn the device off and turn it on again. Press and hold the Sleep/Wake button on the top of the device for few seconds until a red slider appears, and then slide the slider. Then press and hold the Sleep/Wake button until the Apple logo appears.
- If the device did not turn off, reset it. Press and hold the Sleep/Wake button and the Home button at the same time for a least ten seconds, until the Apple logo appears.
