How to Create a virtual home button, if the physical one is broken
If your physical home button is broken or lost functionality, you can give your iPad new life by creating a virtual home button on the screen.
Do you have an iPad without a working home button? Do not worry anymore.Now it is very easy to make a home button on the screen of the iPad through which it will regain some of its functionality. Like several other things, the trick is to use a feature Apple has designed for people with special needs.
Go into Settings> General> Accessibility> Assistive Touch and turn it on.
Now you will see a new button at the bottom right of the screen. If you press it, you will get a different option, such as a virtual home button.
Of course, this can not replace the button totally, but in many situations it will be better than nothing.
