iPhone: Troubleshooting touchscreen response

Resolution

If your iPhone is experiencing any of the symptoms listed above, try the following steps:

1. Clean the iPhone screen with the cleaning cloth that came in the box with the iPhone.
2. Do not wear gloves while using the touchscreen. 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.
3. If you have a protective plastic sheet or film on the touchscreen, try removing it because it may be preventing the touchscreen from working properly.
4. The current application may not be responding (frozen), press and hold the Home button below the screen for a least six seconds, until the application you were using quits.
5. If that doesn't work, turn the iPhone off and turn it on again. Press and hold the Sleep/Wake button on the top of the iPhone 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.
6. If the iPhone did not turn off, reset the iPhone. 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.

If the steps above don't resolve your issue, please schedule a service appointment with an Apple Retail Store for evaluation, even if your iPhone is out of warranty. If an Apple Retail store is not an option, contact Apple to find out your best service option or see the iPhone Service FAQ.

Tip: If you are going to take your iPhone into a Apple Retail Store for evaluation, follow these steps to help the Mac Genius understand where your touch screen is experiencing unresponsiveness.

• Open the basic calculator application to test all but the top row of the screen. Press each button on the calculator and verify activity.
• To test the area at the top of the screen, rotate the iPhone to change to the scientific calculator and press all the buttons in the left two rows. (An original iPhone must have iPhone 2.0 software installed to access the scientific calculator feature.)
• To test the touchscreen function at the top of the screen of an original iPhone without the iPhone 2.0 software, press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. If the slider does slide, press and hold the Sleep/Wake button until the Apple logo appears to turn iPhone on again.
