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 if your device has a Home button. If your device doesn’t have a Home button then follow the instructions below.

• 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.

[Update early 2018: Apple introduced a new way to perform a hard reset, in 2017, with the introduction of the iPhone X since it was the first iPhone to not include a Home button.

Instead of holding down two buttons until the iPhone restarts, you now need to press two buttons quickly and then press and hold a third button. This takes a little practice, but once you get the hang of it you’re good to go.

• Quickly press and release the Volume Up button
• Quickly press and release the Volume Down button
• Press and hold the side button (aka the Sleep/Wake button) until the Apple logo appears.

You must press the volume up then volume down pretty quickly, but not at the same time. The side button is what Apple calls the Sleep/Wake button. After a few seconds of holding the side button, the iPhone should restart.]
