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.
Tablet users can install iPadOS 15.0.2, which also came out Monday.
