What you need to know

  • It is November 2021, and that means it's time for the monthly Surface Duo update.
  • All that's on the docket this month is the classic Android security update patch note.
  • Software versions for this update are 2021.1019.24 (North America), 2021.1019.26 (Europe), and 2021.1019.25 (AT&T locked Duo).

Another month of Surface Duo updates. Or, as they are now unofficially called, Android Security Bulletin PSAs. Here's the only item on November 2021's Duo update log: "Addresses scenarios outlined in the Android Security Bulletin – November 2021."

That's it. Get your security update, and get on with life, because Microsoft doesn't have any other goodies to offer at the moment, especially not of the variety many Duo owners are waiting on. Here's the new version number for each classic Duo type:

  • 2021.1019.24 (North America)
  • 2021.1019.26 (Europe)
  • 2021.1019.25 (AT&T Locked Device)

You can read the November 2021 Duo update log on Microsoft's site, (opens in new tab) but you've already read its entire contents here, so, yeah. The whole update clocks in at 42.74MB in size.

Perhaps you're wondering if there's a different Duo product that Microsoft is focusing its attention on. Something like a Surface Duo 2. Well, you'd be correct, as there is indeed a Duo 2 that's been hogging the limelight for much of October and November. The sequel device is expensive, but if you have an original Duo, you may still be eligible to trade it in at Best Buy and shave $700 off the price of the newer, fancier foldable.

Alternatively, you can hold onto your original Duo and wait for the day Microsoft decides to give it an Android OS bump. There's no telling when that day will be, but it should be "soon." Probably. Maybe.

  • Not too late. I hope this is what we can expect moving forward!
  • Essentially do-nothing update, allegedly because MS is focused on the Duo 2, but nothing on Duo 2 to fix serious bugs that have been going on since launch?
  • Maybe Microsoft hates all its customers equally?
  • Except corporate customers.
  • Love my original Duo, nothing feels quite like it in the hand, no trade in deals in the UK and happy to keep mine I've grown quite attached and it's my daily driver... Am grateful for the monthly security updates, gives me a warm feeling inside... 😊
  • I agree with your original Duo sentiments completely!
  • I am really flabbergasted by the way MS is acting; a thirteen years old child would be able to envision a more coherent strategy.
  • I was just thinking. Even on the Duo 2 android 11 is not perfect. It has its own set of issues. Maybe Microsoft is trying to make a stable enough 11 for the duo1 so that it doesnt give us more bugs and issues. That is what I am hoping is happening. I really do not want new issues after I get android 11, hopefully before christmas.
  • Don't you at least want parity with DUO 2 issues?
