How to Close Apps on iPhone XS Published 1 month ago If you recently upgraded from an older iPhone to an iPhone XS or iPhone XS Max you may not know how to close open applications on your iPhone. If you previously owned an iPhone 8, iPhone 7, iPhone SE, or an even older model, you’re used to closing your apps with the physical home button. The iPhone XS and iPhone XS Max don’t have a physical home button which means you need to use screen gestures to close the apps running on your device. While this process might feel a bit awkward at first, it should start to feel normal after a few days.
