The procedure for troubleshooting a freeze on the iPhone varies, depending on when the lockup occurs. Most freezes during operation are temporary problems, typically fixed by restarting the iPhone. However, if an application is consistently freezing, it’s best to stop using the app and contact the developer with the problem. If your iPhone freezes during boot, you’ll need to restore the phone to repair the bootloader, and all data on the device will be erased. If your iPhone persistently freezes even after being restored, the hardware may be failing. At this point, you may want to take it to an Apple store for advice and service. Warnings Writer Bio
