iPhone Home Button Stops Working?
If you experience a problem with lower sensitivity of your home button, which means that it sometimes works and sometimes not (or you need to push it harder), you can fix this issue by recalibrating it using a technique described in this quick video.
Workaround for Not Working Home Button
But what to do when the iPhone home button is not working and doesn’t react at all? Well, there’s no guaranteed technique to fully restore the home button's function by any software tweaks and in the end the best what you can do is going to a nearest Apple Store (if your device is still under warranty) or contact any of local iPhone service centers.
Luckily, there is a workaround solution for not working home button which can help you in the meantime – you can use the AssistiveTouch function from the Accessibility menu in Settings which allows using on-screen software home button. Before describing how to enable this feature, I just want to note that this guide will work on iOS version 5 and higher on all these devices – iPhone, iPod Touch, iPad and the iPad Mini.
How to turn on AssistiveTouch for enabling on-screen home button
To enable AssistiveTouch, go to Settings > General > Accessibility.
Then scroll all the way down to the AssistiveTouch menu item and tap on it.
Then activate the AssistiveTouch function.
After you enable this function, a semi-transparent button will appear on your display and will be visible all the time, no matter which application you use. If it’s disturbing you, you can drag it to any side of the screen at any time.
Tap this button to open the AssistiveTouch menu. You can see that it contains four options, one of which is “Home” option which you can now use as a physical home button substitution.
TIP: The AssistiveTouch menu contains also some other useful shortcuts that you can use for quick setup of your iPhone. Just tap on the “Device” button in the main AssistiveTouch menu. You can lock screen or manually rotate it from this menu as well as changing volume or mute the iPhone completely.
Tap on “More” option to see further options like shaking your device, taking screenshot or multitasking.
The AssistiveTouch menu can be used as a full substitution for the iPhone home button and I believe that it can help also some of you who even don’t have any problem with not working iPhone home button as it has some very useful shortcuts.
