Amid all the talk about Android 12, some people forget that OEMs are still working on updating their smartphones to Android 11. Samsung, for example, has upgraded a bunch of Galaxy devices to Android 11 with the One UI 3.1 skin from the company in addition in recent months. Now, three other Samsung devices – the Galaxy M40, Galaxy Tab Active 3, and Galaxy A31 – are now receiving the same treatment worldwide. Along with them, the Moto G Stylus (2020) has also started receiving its Android 11 stable update in the US.

The OTA, labeled as M405FDDU2CUD2, is live in India at time of report.

Samsung has also started rolling out the Android 11 update with One UI 3.1 for the Galaxy Tab Active 3. The “Active” tag is typically reserved for the rugged lineup, and the Exynos 9810-powered tablet is no exception. Bearing version number T57xXXU3BUD5, the Android 11 firmware comes with the slightly older security patch from March 2021. As reported by SamMobile, the update is currently available for the LTE variant of the tablet (model number SM-T575) in Swiss.
