If you’re like most people, you probably use your iPhone to do a few things at the same time. But if you want to split screen on your iPhone 11, there are a few things you need to know. First, make sure that your device is unlocked. This will allow you to use Split Screen on your iPhone 11. Second, open up the Settings app and select General. Then under “Screen” choose “Split Screen.” Finally, set up how many screens you want to see and how long each screen will stay open. If all of your screens are closed down when you wake up from sleep, then it’s probably not necessary to split screen on your iPhone 11.
