- The Surface Duo is now getting a March Android security update

Microsoft's Surface Duo appears to be back on track for monthly updates as the March 2021 one is now rolling out to unlocked Duos (AT&T branded ones are usually a week later pending approval).
The update contains Android security patches for the month and likely other fixes and improvements as well. The update is 82.39MB in size, which is slightly bigger than last month's cumulative update, which arrived three weeks ago and was just 66MB.
The update bumps the Surface Duo build number from 2021.115.52 to 2021.207.70 and the security patch to March 5th, 2021.
To check for the update, use the following steps:
- Connect to a Wi-Fi network.
- Select Settings on your Surface Duo's home screen.
- Select System.
- Select System Update.
- Select Check for update.
- Select Restart now.

Surface Duo has been receiving many updates for its Launcher and keyboard recently with multiple updates per week. From our own experience, the Launcher has a much more significant impact on gestures, behavior, and smoothness than previously thought, with substantial improvements being observed after each one.
Surface Duo recently went on sale in four new markets including France, Germany, UK, and Canada. And just today, it received support from Xbox Game Pass (Beta) for on-screen controls, which is a killer feature.
For those in the US, a permanent price cut of $400 is now in place six months after the dual-screen device's release.
Double the Android
Two screens are better than one.
Microsoft delves into the future of foldables with an ambitious dual-screen device featuring two ultra-thin 5.6-inch AMOLED displays bound by a 360-degree hinge. This pocketable inking-enabled Android smartphone marks the latest in the Surface lineup, geared for mobile productivity.
