The company has announced the One UI 3.0 beta program for the Galaxy M31 in India. Today, it started accepting registrations to enter the beta program for the Galaxy M31. The first beta update, with firmware version M315FDDU2ZTLF, brings Android 11 to the smartphone along with the December 2020 security patch. The new update should bring a newer UI design, faster performance, improved security, bug fixes, better stock apps, and more optimizations.
If you are a Galaxy M31 user in India, you can join the One UI 3.0 beta program by clicking on the registration banner in the Samsung Members app. After you are accepted into the program, you can check for the update by navigating to Settings » Software update and tapping on Download and install.
Samsung had mentioned in its update schedule that the Galaxy M31 would get the update in March 2021, but the stable update may come out considerably earlier than that. We are not sure if other countries or other Galaxy M series devices will get access to the One UI 3.0 beta program.
Thanks for the tip, Yash!
