- Launch an Apple default app such as the "Stocks" app.
- Hold in the power button on the top edge of your device until you see the "Slide to power off" screen. Then let go of the power button.
- Now hold down the home button and it will kill the Stocks app and the "Slide to power off" screen will disappear.
Apparently this is supposed to somehow reset or re-calibrate the home button. My home button was already working fine so I can't say if it works or not. Though many other folks have said that this DOES work. Let me know!
