In One UI 7.0 and later versions, you can add widgets to your Lock screen and Always On Display (AOD) to easily access concise information without unlocking your device. This feature enhances the usability of your device, allowing you to check essential details quickly.
How to Add Widgets to the Lock Screen and AOD?
1. Press and hold any empty area on the lock screen. 2. Tap the ‘Add Widgets’ area that appears. 2. Select and add one or two widgets that you want to display on the lock screen or AOD. 4. After adding, tap ‘Done’ to save your changes.
You can now use the Brief widget and Now bar instead. Most of the functions previously available in the Face widget are now accessible through the Brief widget and Now bar.
To control your interest, navigate to and open the phone's Settings, tap Lock screen and AOD, and then tap Now bar.
