The home button is the biggest catch on iOS gadgets 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 numerous Android gadgets, home is a software button that disappears inside applications, leaving you feeling stuck, however the physical home button on iOS gadgets 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 truly make using the gadget frustrating, especially if you’re using an older gadget that doesn’t support gestures. If you’re facing the same issue, then you should enable the software home button option on your iOS gadget, and this is the manner by which you do it:
