If you’re like most people, you probably use your iPhone to do a lot of things. From browsing the web to checking email, you might be using the phone in multiple ways at once. To make sure that everything is working as it should, it’s important to split screen on your iPhone. To split screen on your iPhone, open up the Settings app and select “General.” Under “Split Screen,” select “On.” Then, under “Type of Screen,” select “iPhone.” Finally, under “Width,” select “Width of Screen” and set it to the desired amount. If you want a smaller window in the center of your screen, set this value to “-1.” If you want a larger window on one side of your screen, set this value to “+1.” Now that you’ve set up split screen on your iPhone, all you need to do is use it! To start splitting screen mode on your iPhone 7, just press and hold down the power button for two seconds. Once Split Screen is activated, use any app or device that can be used insplit-screen mode (like an iPad) to start using it.
