The following are the known iPad Touchscreen issues:
- Dead spots on the touchscreen – A good method to test the touchscreen is to download any app that allows you to draw and then test every inch of the touchscreen to ensure that there are no dead spots.
- The touch syndrome – The best method to test is to turn off the auto screen lock feature in settings and let the iPad stay on the home screen. Watch the iPad for 2-3 minutes and you will know if the iPad has touch syndrome if it will magically open apps on its own or if the iPad will mysteriously swipe to another page on the home screen.
- If the iPad you are troubleshooting has any of the problems listed above then follow the following steps:
- Hard reset – Hold the home button and the power button till you see an apple logo and then release it. Wait till the iPad shows the home screen and test it again to see if the problem is solved.
- Check the Touchscreen cable – Ensure that the touchscreen ribbon cable is inserted properly in the connector. Make sure the cable is inserted all the way. Re-assemble the iPad & test again.
- Replace with a new iPad Touchscreen – If the above two steps does not fix the issue then the iPad Touchscreen is defective and has to be replaced.
