Samsung opened the Android 11-based One UI 3.0 beta program for the Galaxy M31 last month, and now it has released the stable build of the One UI 3.0, making the M31 its first mid-range phone to get One UI 3.0 stable update.
The One UI 3.0 update comes with firmware version M315FXXU2BUAC and January 2021 Android security patch as well as redesigned UI and new features to the Galaxy M31. You can check out the screenshots of the changelog below for more details.
The One UI 3.0 update for Galaxy M31 is currently rolling in India for beta users and requires a download of about 400MB, but those who didn't participate in the beta program should get it soon.
My Galaxy M31s is also having hang and auto re-starting issues after software upgrade. I am asked to replace Motherboard that costs around 8000. I regret buying Samsung product.
I am also facing similar issue. You should reach out to Samsung customer care head or someone senior.
