Overview

  • Samsung has begun delivering the stable One UI 8.5 build to the Galaxy Tab S11 and Tab S11 Ultra in South Korea, replacing the month‑old tablet beta.
  • The tablet firmware arrives with build codes X736NKOU5BZE3 for the base Tab S11 and X936NKOU5BZE3 for the Ultra.
  • One UI 8.5 brings visual polish and new capabilities, most notably Apple AirDrop compatibility, a more customizable Quick Settings panel, and refinements to Galaxy AI features.
  • Samsung typically expands updates from South Korea to other regions in staged waves, so broader distribution to eligible tablets is expected in the coming days.
  • Users can check for the update on their Tab S11 series via Settings > Software update > Download and install, and the release follows earlier One UI 8.5 phone rollouts and ongoing One UI 9 beta testing for Galaxy S26 devices.
