Most of the time, your iPhone 11 freezes because of a software problem. A hard reset will usually unfreeze it, but that doesn't actually fix the deeper software bug that's causing the issue. Even if a hard reset fixes the problem, make sure to check for an iOS update.

With a soft reset, the operating system is rebooted and all services reloaded. If you use this method of resetting, all your personal data, files and apps on the device will remain unchanged.
