Surface Duo's October 2021 Android security update has arrived

It's as light as updates get.

What you need to know

• The October 2021 Surface Duo security update is here.
• It's 51MB in size.
• It brings the version number up to 2021.913.25 for those in North America, 2021.913.26 for Europeans, and 2021.913.27 for locked AT&T device users.

Another month, another Surface Duo update. This time around, it's an extremely lightweight 51MB update that "addresses scenarios outlined in the Android Security Bulletin - October 2021." That's the entirety of Microsoft's update log for the month.

Here are the new version numbers:

• 2021.913.25 (North America)
• 2021.913.26 (Europe)
• 2021.913.27 (AT&T Locked Device)

In short, it's not a grand update. What is a grand update is the Surface Duo 2, which will be getting the lion's share of Microsoft's attention from now on. It has a new camera setup and other improvements custom-built to improve upon the original Duo, which is still doing its thing and giving us a reason to post these monthly update logs.

Stay tuned for any major Android updates that may befall the original Surface Duo in the near future, be that in November or December. Or, if not by the end of 2021, then January or February. Basically, expect a big update at some point soon.

Thanks, Andrew R., for the tip!

Duo dabbling

Even with the Surface Duo 2 set to replace the original, there are still many people enjoying the classic Duo experience. If you're interested in getting the original on the cheap (relative to the $1,499 sticker price of the Duo 2), now's not a bad time to buy. Especially since the OG Duo often goes on sale for under $400.
