What you need to know

  • Microsoft is rolling out the June OS update for Surface Duo.
  • The update is 84MB in size and brings the OS security patch to June 5th.
  • The version number is now 2021.525.62.
  • A changelog is now live and posted below.

Microsoft has started rolling out its June security update for the Surface Duo, bringing with it the latest security patches from Google in addition to general OS bug fixes and enhancements. Microsoft has committed to releasing monthly OS updates for Surface Duo, and the June update is right on schedule.

The update bumps the version number from 2021.419.70 (US) to 2021.525.62.

The official changelog (opens in new tab) has now been posted and is as vague as ever:

  • 2021.525.62 (North America) / 2021.525.64 (Europe)
  • Addresses scenarios outlined in the Android Security Bulletin - June 2021.
  • Improves device and UI stability.

The update is only about 84MB in size, making it the smallest monthly security patch yet. This likely means there's not much new or changed with this release. Last month's OS update was around 197MB for comparison. The update also brings the OS security version to Google's June 5th security patch.

To grab the update yourself, use these 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.

The update is rolling out now for unlocked models of the Surface Duo. The update for AT&T handset usually arrives a couple of weeks later. What are your thoughts on Surface Duo's monthly OS updates? Let us know in the comments.

  • Now that windows 11 runs android apps will we get a true windows phone running Android phone apps
  • Apparently the Intel Bridge and Windows Subsystem for Android running on ARM doesn't need to use emulation. But I still think we're 2 years away at least.
  • You already know the answer brotha.
  • The way I see it is yes, it's technically possible that Microsoft can and may release a Duo running Windows at some point. Whether that's Windows 11, a Core version, or something else remains to be seen. The likelihood of that right now is slim to none. Microsoft wants Windows 11 to be a PC operating system first and foremost. It's not made to run on anything less than 9 inches. That's not saying you won't have smaller devices, but it's certainly not made to be a phone OS. Eventually those puzzle pieces may potentially be added in, but it's just not in the cards. The Duo running Android is the closest you're going to get to a phone running Windows for the foreseeable future
  • Windows 11 requires a screen size of at least 9 inches. While they could always change that, Windows on a phone screen makes no sense. Having an Android phone without Google Play Services would not be a good experience for most either.
  • Also, Windows Central can you please fix the scrolling in your Android app? It's very unreliable and kinda "sticky" on the Surface Duo.
  • Same for OnePlus 6... It's that way for months now...
  • Yes please, x2.
  • Wow... they got the June update out before t-mobile got the S21 updates out!
  • Interesting. I'm in the UK and got this update several hours ago (actually 5pm yesterday afternoon local time). And my version is 2001.525.64
  • I have the locked Att version so maaaaaybe I'll get this on time.
  • nope lol you know its gonna be late like always
  • Still getting screen blanking (ever since April update)
