The Home button got to be the most problematic hardware on the iPhone.
Recently, my iPhone 4 Home button started to respond slower. I either have to press multiple times, or press harder.. If you faced the same problem, you are not the only one.
Luckily, there is a fix for it! I tried the fix, and it did work help! Here is what you need to do:
- Open any application
- Press and hold the power button until the slide to shutdown swipe bar appears.
- Release Power button
- Press and hold Home button lightly, until screen returns to icon screen
- Enjoy your functioning home button!!!
This procedure recalibrates the home button after normal wear or heavy use.
