The home button is the biggest button on iOS devices and probably the most important one. It’s a great example of what makes the iPhone and iPad so easy to use, that single button will always take you to the homescreen no matter what you’re doing. On many Android devices, home is a software button that disappears inside apps, leaving you feeling stuck, but the physical home button on iOS devices is always there. At the same time, power users can double and triple tap the button for additional functions. Unfortunately, this extensive usage means that the home button can become unresponsive. This can really make using the device frustrating, particularly if you’re using an older device that doesn’t support gestures. If you’re facing the same problem, then you should enable the software home button option on your iOS device.
