Solving Common Issues
If the iPhone is frozen or not operating as expected, the six tips that follow will help you resolve most common issues. Try the tips in order, continuing to the next tip if the prior one does not work.
- If the screen displays "Charging. Please wait...," keep iPhone connected so it continues charging.
- Use a high-power USB port, such as the one on a computer, or use the iPhone AC adapter.
- Don't use the USB port on a keyboard because it is a low-power port and iPhone will not charge.
To close a frozen application, press and hold the Home button below the screen for at least six seconds, until the application quits. Then try restarting iPhone.
To restart iPhone, turn it off and turn it on again. Press and hold the Sleep/Wake button on top of iPhone for a few seconds until a red slider appears, and then drag the slider. Then press and hold the Sleep/ Wake button until the Apple logo appears.
iPhone OS 3.0: Press and hold the Sleep/Wake button until the red slider appears, then press and hold the Home button until the application quits.
iPhone OS 2.x: Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears.
If iPhone is not working as expected, it may be due to some of the content synced to it. Try selectively removing certain content that may be causing unexpected behavior such as contacts, calendars, songs, photos, videos, or podcasts. To remove content, connect iPhone via USB and use iTunes to change the sync settings. Click iPhone in the Source list, and select each tab to change what content is synced then click apply.
If possible, sync iPhone with iTunes to back up the most recent settings. From the Home screen, tap Settings > General > Reset > Reset All Settings to reset iPhone settings. All preferences are reset, but no data or media is deleted.
If the issue is still not resolved, erase all content on iPhone by tapping Settings > General > Reset > Erase All Contents and Settings. All data and content will be erased from iPhone and all iPhone settings will be restored to their original state.
Try restoring iPhone using the latest version of iTunes. Connect iPhone, and when it appears in the Source list, click Restore in the Summary tab.
Important: If you restore iPhone, all customer data will no longer be accessible, including songs, videos, contacts, photos, calendar information, and any other data. All iPhone settings are restored to their original state. If possible, sync iPhone with iTunes before restoring to back up the most recent settings.
