Did your iPhone or iPad freeze and stop responding? If so, perform a hard reset. This procedure will fix many small issues. If your device continues to freeze then you may need to take more extensive measures, like performing a factory reset or taking it to the Genius Bar at an Apple Store.
Here are instructions on how to perform a hard reset:
- Press and hold the Home button and the Sleep/Wake button on your device until your iPhone or iPad turns off and then displays the Apple logo as it starts up.
The Home button is the big round button on the front of your iPhone or iPad at the bottom of the display.
The Sleep/Wake button is located on the top edge of the most iPhones and iPads. However, starting with the iPhone 6, the button moved to the right edge of the iPhone.
Your iPhone or iPad should start up. Hopefully, it will work properly.
