Yes, the Always-On Display (AOD) on the Samsung Galaxy S23 Ultra can be used with the S Pen. Users can take advantage of this feature to write notes directly on the AOD while the phone is asleep. This allows for quick jotting down of reminders or ideas without needing to unlock the device. Once written, notes can be pinned to the Always-On Display for easy visibility[4][6].
Additionally, the S Pen on the S23 Ultra supports various functionalities, including Air actions and handwriting recognition in apps like Samsung Notes. The S Pen is conveniently stored and charged within the device itself, making it readily accessible for use with the AOD and other features[1][2][3].
