The quad rear camera setup features a 64MP primary (wide, f/2.0) lens + an 8MP secondary (ultrawide, f/2.2) lens + a 5MP (macro, f/2.4) + a 5MP (depth, f/2.2) lens along with an LED flash, PDAF, HDR, Panorama, etc. On the front side, the device sport a 16MP selfie camera (wide, f/2.0) lens with HDR, Portrait mode, AI Face Unlock, etc.

One UI 4.0 Upgrade and Features
Of course, the Samsung Galaxy M31 came out of the box with Android 10 and later received the Android 11 update. According to Samsung’s recent policy change, their device will get three years of major OS support and four years of a security patch update. As promised, finally, Samsung started rolling their One UI 4.0 update to their flagship and feature-rich smartphone.
One UI 4.0, which is based on Android 12, brings an entirely new UI design with a simplified color palette feature and the game-changer Android 12’s material YOU design that lets users significantly personalize the look and feel of the UI.
