Samsung Galaxy M31s Specifications: Overview
Inside the Galaxy M31s, we have the Exynos 9611 SoC powering the phone. While it isn’t known for good performance, it still delivers decent speeds in synthetic benchmarks and casual games. The Galaxy M31s is also backed up by 6GB of RAM and comes with a storage of 128GB that is non-expandable. Pair that with the massive 6000 mAh battery, and the M31s is an absolute powerhouse of a phone. Samsung also bundles within the box a 25W fast charger to quickly juice up your phone in dire situations.
The entire phone is made out of “Glasstic” which is just a fancy way of saying frosted plastic. It does feel rather premium thanks to the engineering that Samsung has put into this phone. The Galaxy M31s come out of the box with Samsung’s OneUI 2.1 which runs atop Android 10. It is expected to receive the latest versions of Android and OneUI as well. The M31s has a quad-camera setup to the rear with a configuration of 64+12+5+5MP which seems to be an overall good setup for taking photos in well-lit situations. The front camera is a 32MP sensor that takes some really crispy selfies.
