It is easy to forget about your iDevice’s home button while you are mesmerised by it’s gorgeous display. No matter what, the home button may be the most important part of your iDevice. It enables you to multitask, quit applications, and use Siri, just to name a few things. After a while, your home button may start to seem a little laggy or unresponsive. Luckily, you can fix that problem in three easy steps:
Step 1: Launch one of the stock apps on your iDevice (Weather, iTunes, Stocks, etc.).
Step 2: Press and hold the power button until you see the “slide to power off” prompt, then release the power button.
Step 3: Press and hold you home button until the “slide to power off” prompt disappears and the app force quits.
You should now be on your home screen and your home button should be recalibrated! Recalibrating your home button this way will work on your iPhone, iPad, and iPod touch.
