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 comes out of the box with Samsung’s OneUI 2.1 that 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.
