If you broke your iPhone Home button or any iOS Home button.. Don’t worry you can actually have a Home-button-like function on your touch screen by enabling Assistive Touch.
1. Go to Settings.
2. Go to General.
3. Go to Accessibility.
4. Scroll down to Assistive Touch and turn it ON.
5. You will see a square box with white circle in it, almost the same size of the Home button on the screen.
Note: Tested with iPhone 5 with iOS 8.1.1
