The original Microsoft Surface Duo shipped with Android 10 out of the box, and the phone's software experience was famously buggy. Microsoft rolled out a few fixes in the months after release, but the company eventually shifted its resources to bringing the Surface Duo 2's updated software (based on Android 11) to the original model. After missing its original deadline, the first Surface Duo finally has its Android 11 update.

Microsoft said in September that Android 11 would arrive before the end of 2021, but the company failed to reach that goal. The update finally started to roll out on Monday (via Windows Central), but only for the carrier-unlocked Surface Duo in North America and Europe — the upgrade for the AT&T Surface Duo is still in the testing phrase. The full changelog is below.

The most important change here is that the Surface Duo now runs Android 11, which includes a Conversations section in the notification shade, built-in screen recording, more permissions options, and other improvements. Microsoft also bundled the January 2022 security patch. Finally, all of the software features from the Surface Duo 2 are present — opening OneNote with a button press on the Surface Slim Pen 2, more options for phone calls, an updated app drawer, a new Photos app, and more.

Earlier this month, Windows Central reported that Microsoft might skip updating the Surface Duo to Android 12, and simply wait for Android 12L to be ready. Google is expected to release the final build of Android 12L sometime before the end of March. The second beta of Android 12L was released for Pixel phones on January 12.
