Microsoft appears to be trying to catch up on Surface Duo updates after its missed December and late-delivered January ones (released January 27th).

Unlocked Surface Duos should now be getting the February 5th Android security update bumping Duo’s system build from 2020.1211.85 to 2021.115.52.

For those with AT&T-branded Surface Duos, that update likely won’t go out for another week when the carrier certifies it.

The update is only 66 MB in size, suggesting it is just essential security updates. However, Microsoft has yet to post the official changelog, so we can’t be certain at the time of this posting (we’ll update when that goes live).

To check for the update, use the following steps:

  1. Connect to a Wi-Fi network.
  2. Select Settings on your Surface Duo’s home screen.
  3. Select System.
  4. Select System Update.
  5. Select Check for update.
  6. Select Restart now.

For those looking for news on Android 11, a recent report (corroborated by our sources) points to a mid-year or summer release for the more extensive OS update. However, Microsoft has yet to confirm the details publicly.

Surface Duo is also going on sale today (February 18th) in four new markets including the UK, Germany, France, and Canada, which is likely tied to the timing of this update.

Thanks for the tip, Ryan T.!
