One UI 3.1, which debuted with the Galaxy S21 series earlier this year, is quickly rolling out to various Galaxy smartphones and tablets. After releasing the Android 11 update to the Galaxy M31s in Russia last week, Samsung has now started rolling out the One UI 3.1 update to the mid-range smartphone in India.
The Android 11-based One UI 3.1 (Core) update for the Galaxy M31s, which has firmware version M317FXXU2CUB1, also brings along the February 2021 security patch. The update has a download size of 1,932.15MB, so we advise you to download it via a Wi-Fi network. The update brings a refreshed UI design, one-time permissions, permissions auto reset, dedicated media player widget in the quick settings panel, a conversations section in the notifications area, improved Digital Wellbeing and Parental Controls, and improved performance to the Galaxy M31s.
Samsung has mentioned in the update's changelog that app copies made using Dual Messenger can no longer access files on the microSD card directly. Instead, users would have to go to the Gallery or My Files apps, select the required file, share it using the Share Sheet, and then select the copy of the app. The update also brings improved stock apps, introduces new features to Samsung Keyboard and Samsung Internet apps, and speeds up app launches.
If you are a Galaxy M31s user in India, and if you haven't received the latest software update yet, you can check for it manually by navigating to Settings » Software Update and then tapping on Download and install. The update will reach other markets gradually.
