STEPS
TOOLS
Open a stock application like the Calendar, Weather, or Youtube
With one of these apps opened, hold down the power button until the 'slide to power off' control appears.
As soon as you see it, press the home button and keep it pressed until the red slider disappears and the app is forced quit to the home menu.
That's it! Now you should have a much more responsive home button.
