Split Screen - How to Remove

How to get rid of a split screen on your iPad

If two apps are side-by-side with a divider between them, drag the bar all the way to the right or left. If you drag it to the right, you'll close the app on the right. If you drag it all the way to the left, you'll close the app on the left. In both cases, the app that's left open will go full screen.

If the second app is floating on top of the main app, tap and hold the top of the floating app, and drag it downward. It'll then snap to the right side of the screen. Now you can close it by dragging the divider. You can also swipe it to the right to close it temporarily — swipe left on the right side of the screen at any time to bring it back.

How to permanently turn off split screen on your iPad 

1. Open the Settings app.
