iPhone users should install the latest system software update because it fixes a collection of bugs. Monday’s release of iOS 15.0.2 takes care of images that couldn’t be deleted, problems with AirTag and iPhone Leather Wallet, and more. More significantly, it (and a related iPadOS update) deals with a device restore/update issue with iPhone 13 and the new iPad mini. If you’re unsure whether your AirTag is up to date, you can check the current AirTag firmware version to stay on track.
Tablet users can install iPadOS 15.0.2, which also came out Monday.
