Troubleshooting

Sometimes your iPhone can lock up completely and not respond to any input. In this case, the iPhone can usually be forced to reboot.

On the iPhone 6s, iPhone 6s Plus and earlier models:

1. Hold down the sleep/wake button and home button simultaneously.
2. Let go when the Apple logo appears and the iPhone is booting up.

Starting with the iPhone 7 this procedure has changed. Click here to see the button combination that resets the iPhone 7, iPhone 7 Plus and later.

If your iPhone fails to boot up repeatedly you may have to restore it with iTunes and your computer. To restore the iPhone completely follow these steps:

1. Before you connect your iPhone with the USB cable, start iTunes. Make sure iTunes is finished downloading podcasts, updating, etc.
2. Connect your iPhone to the computer and wait 10-15 seconds for the connection.
3. Press and hold both the sleep/wake button and home button on your iPhone.
4. After 10 seconds, release the sleep/wake button and continue to hold the home button only.

When your iPhone drops calls left and right even with a strong signal indicated, there are a few things you can do to correct the problem:

1. Turn your iPhone off once a day for 30 seconds. This will reset its communication with cell towers in the area.

2. Turn off 3G service and use EDGE. Settings -> General -> Network -> Enable 3G. Users have experienced more voice stability with EDGE in some areas.

3. Call your service provider. They will know if cell towers are degraded in your area. Your carrier can also file a report for network technicians to investigate.

Sometimes an iPhone app will become unresponsive, and no matter what buttons you press or where you touch on the screen nothing happens. In this event, sometimes it helps to force quit the application.

Apple has made some changes with the iPhone OS 3.0 firmware and the iPhone 3GS release. Those with older iPhones will remember that to force quit an application you could just hold down the home button until the app exited.

Some users have found that downloaded applications have stopped working on the iPhone 3G. In addition to this bug, media such as music suddenly becomes invisible even though the files remain on the device.

There are several suggested workarounds for this issue until Apple releases a fix in September. Please refer to this article for one comprehensive solution.
