The Samsung Galaxy M31s is the successor of the Galaxy M31 and brings new features to the segment. The Galaxy M31s sports a 6.5-inch Infinity-O AMOLED display with a hole-punch at the centre. Just like the Galaxy M31 this too packs a big 6,000mAh battery but this time around Samsung has paired a 25w charger in the box.

Samsung has also gone with a side-mounted fingerprint scanner on the Galaxy M31s. The phone has a “Glasstic” back which looks like glass but is actually made out of plastic. It is a fingerprint magnet and picks up fingerprints very easily. The phone runs OneUI 2.1 on top of Android 10. The Galaxy M31s comes with a fair amount of bloatware preinstalled on the device. 
 

Samsung has opted for the Exynos 9611 SoC to power the Galaxy M31s. This is a dated processor at this point and you do see some sluggishness while loading heavy apps and games. Battery life on the Galaxy M31s is impressive as the phone lasted us over 2 days with our usage. The Galaxy M31s has a quad-camera setup at the back consisting of a 64-megapixel primary camera. We found the camera performance to be good in daylight. It also has a Single Take feature which offers different outputs after recording a video. Lowlight camera performance was average but the found video stabilisation to be poor.
