Apple is reportedly testing a new home screen customization option in iOS 27, which will make it easier for users to lay out apps and widgets on the iPhone home screen. The changes will add two buttons to the existing menu, one for undoing a change and the second for re-imposing a change. This could potentially help users who are indecisive about making a change without making many other alterations. Other notable changes include a Liquid Glass adjustment slider, Siri upgrades, and performance and battery life improvements.
