Occasionally a buggy app or a new iOS update will result in instability that sometimes causes your iPhone to freeze or become otherwise unresponsive. Instances of this sort require you to force a reboot (aka hard reset, hard reboot, force restart, force reboot). A force reboot will retain your data, so it's not like doing a factory reset which erases everything. Hopefully after restarting you will be able to get rid of the offending app or revert to an earlier more stable version of iOS.

Android phone owners switching to Apple iPhone can easily transfer their data. iOS has made the process of moving important data such as contacts and photos from Android to a new iPhone simple. Once completed, the new iPhone is set up automatically thanks to the Move to iOS app. Everything from browser bookmarks to Google account information can be selected for transfer to the new Apple hardware.

Arizona is breaking new ground as the first state to support Apple's digital state ID and driver's license. Residents can submit their digital ID for approval, which adds the document to the Wallet app on iPhone. Once added, the iPhone or Apple Watch can be used to present the digital ID in place of a traditional card at TSA checkpoints in Phoenix Sky Harbor airport. Apple plans to launch the technology in additional US locales soon.
