What to Do If the iPhone Stops Responding /Freezing

Sometimes, your iPhone won’t respond to your touch—it freezes in the middle of a program. If this happens, try these steps to see whether the iPhone will start responding :

1. Click the Home button once to see whether that exits the app to the Home screen.
2. If one particular app is causing trouble, try double-clicking the Home button to open the App Switcher bar. Then press and hold any icon in the App Switcher bar until they all shake and a red circle with a minus sign appears in the upper-left corner of the icon. Tap the red circle icon to close the app.
3. If the iPhone continues to be unresponsive, try pressing the Sleep/Power key until you see Slide to Power Off. Then press and hold the Home button until you return to the Home screen—this should quit the program.
4. Make sure your iPhone isn’t running out of power. Try plugging it in or attaching it to your computer (if it’s plugged in) to see whether it will start to respond.
5. If holding the Home button doesn’t work, you will need to try to turn off your iPhone by pressing and holding the Power/Sleep button for 3–4 seconds. Then slide the Slide to Power Off slider at the top of the screen. If you cannot power off the iPhone, then see the following instructions about how to reset the iPhone.
6. After you power off the iPhone, wait a minute or so, and then turn on the iPhone by holding the same Power button for a few seconds.
7. You should see the Apple logo appear on the screen. Wait until the iPhone starts up, and you should be able to access your programs and data.

If these steps don’t work, you will need to reset your iPhone.
