Been having issues with the home button on my ipad2 for a couple of days. Button would just stop working, but then start again if you held it while rotating the iPad.
Just performed these instructions to re calibrate it
- Open a stock iOS app, such as Contacts
- Press & hold the sleep/wake button at the top of your device until the red slider control appears.
- Immediately release the sleep/wake button and press & hold the Home button. Hold until the red slider disappears. Release the Home button.
You should now be on your home screen and your Home button should be recalibrated!
