Once your iPhone has fully restarted, try opening an app and see if it works normally.

Tip 2. Quit and Restart the App

There is no guarantee that the first method always works. Sometimes the app crashes when you are using it without any symptoms. When an app freezes, crashes, and does not work as intended, you can force close the app and reopen it rather than reboot the device.

  • For iPhone X and later: Swipe up from the bottom of the Home screen and pause in the middle. Swipe right or left to find the app that you want to close. Then drag the app's preview card up to close it.

  • For iPhone 8 and earlier: Double-click the Home button to open the recently used apps. Swipe right or left to find the one you want to quit, then swipe up on the app's card to close it.
