How to Add Touchscreen Home Button on iPhone, iPad
The home button is the biggest button on ios device and probably the most important one. The home button is that single button which will always take you to the homescreen no matter what you're doing. On many Android devices home button is a software button on the Touchscreen that gets disappeared inside apps, thus leaving you feeling stuck, but for iOS devices, the physical home button is always there. Also, the power users can double and triple tap the button for additional functions.
Unfortunately, the extensive usage of home button, particularly if you're using an older device that doesn't support gestures, may lead it to become unresponsive thus can make using the device frustrating. If you're facing the same problem as i used to, then you should enable the software home button on Touchscreen option on your iOS device. This is how you do it :
1. Open Settings.
2. Go to General > Accessibility
3. Scroll down to the section labeled INTERACTION and tap on AssistiveTouch.
4. On the next screen, toggle AssistiveTouch to the green On position.
5. A white circle with a grey box will appear on screen. Tap this circle to expand it to a big box on screen. The square Home button at the bottom of the box functions exactly like the physical home button - you can use it to single tap, double tap, or long press the home button even if there is a hardware problem. The grey box remains visible and usable in all apps.
