Samsung’s One UI on Android 17 is expected to bring a big upgrade to the Always-On Display (AOD). Most Android phones already have AOD, which keeps your screen on to show the time, notifications, and other small details. While it is useful, it only shows limited information and uses some extra battery.

With Android 17, Google is working on a new feature called “Min Mode.” This will let apps show their own simple, full-screen views on the AOD. Instead of just a clock or notifications, apps could display more useful information while keeping battery use low.

Min Mode will use the same low-power mode as regular AOD, keeping the screen dim and simple to save energy. Apps that want to use this feature will need to set up a special screen called “MinModeActivity.” When the phone is idle, Android will show this screen on the AOD.

To prevent screen burn-in, it will move pixels slightly every minute. This allows apps to provide useful information at a glance without draining the battery.

Google Maps is one of the first apps likely to use this feature. It is preparing a low-power navigation mode that removes most buttons and uses a black-and-white display. The mode will only work in portrait orientation, which fits the AOD style.

Min Mode could eventually be available to other apps through a developer tool, allowing more apps to show glanceable information while the screen is off. The feature is expected to launch with Android 17, which makes AOD much smarter and more interactive.
