Microsoft’s Surface Duo is in the process of receiving its April 2020 update.

The update will likely contain an assortment of improvements, one of which will be an Android security patch. Given that April’s update is 338MB in size, which is far bigger than previous months, there might be a number of noteworthy changes included.

This patch brings the build number from 2021.207.70 to 2021.314.91, with the security patch now being April 20, 2021.
