How to calibrate your home button
Sometimes when you press the home button on your iPhone, iPad, or iPod Touch there can be a delay or even take a couple of tries before it responds. In this tutorial you will see how to fix this.
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.
