The slight movement of the fingerprint icon on the Always On Display (AOD) is expected behavior. It's a built-in feature designed to prevent screen burn-in by periodically shifting the icon's position.
We understand this might seem unusual at first, but rest assured, it’s part of the display protection system and doesn’t affect fingerprint recognition or overall performance.
If you'd prefer to reduce the distraction, you can:
Turn off AOD under Settings > Lock screen > Always On Display, or change the AOD style to one that only shows the icon on tap.
