What you need to know

  • The Surface Duo has a launch day firmware update.
  • The update improves device, calling, and camera stability.
  • Software updates roll out in stages for the Surface Duo.

This update should also bump the Android security patch to September 5th and is the same one Surface Duo reviewers received a few days ago.

Surface Duo checks for OS and system updates during the out-of-box-experience and device setup process for new owners. While you can skip this process (and do it later), this update does bring many improvements that you will want right away.

The full changelog of the update appears on the new Surface Duo update history page, which might be worth bookmarking. The page points out that updates for the Surface Duo roll out in stages, so you might not see this update right away.
