The Samsung Galaxy M31 managed to make a good impact in the budget segment thanks to its crisp AMOLED display and a big battery, which helped distinguish it from the competition. Samsung has now launched its successor, called the Galaxy M31s. The new Galaxy M31s sports an Infinity-O display and the Single Take camera feature, both firsts for the Galaxy M series. Starting at Rs. 19,499, do these new features justify the higher price? I review the Galaxy M31s to find out.

Samsung Galaxy M31s Summary

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.

  • Honest review. Not upto the mark phone at this price.
    Vikas A Hamasagar (Jan 22, 2021) on Gadgets 360 Recommends
    After using the M31s phone for almost a month and more I found some of the points which I seriously want to share here. 1. The face recognition is not at all upto the mark. It doesn't respond quickly when I try to unlock my phone. It's definitely a big issue when I want my M31s phone to access quickly, my phone never support at the moment. Frustrated many times due to this. 2. Fingerprint sensor is also a big negative remark which used to respond good during the earlier days but gradually the response time is taking too longer to unlock my phone. 3. The body of the phone is not at all good. It looks so cheap because the back portion of the phone is totally plastic body and the scratches appear so soon and clear even if you use a high quality phone case to it within a span of 1month of usage. 4. Especially about the camera, if you are looking for a good selfie camera don't go with this phone. While taking a selfie the camera gets stucked showing a pop-up "Warning camera failed" which is definitely one of the major issues. I have seriously experienced alot of such embarassing moments due to this. Here I have reviewed only the few negative one's because these are major issues which I found and I must say the rest of the features inside are quite good. But the price which I have afforded for this phone is too high as per features ranged phones and every feature should be perfectly good within the price range. Its not like we are giving money to the phone and he gives good features to some extent and worst features to some extent together in bonus. I sincerely suggest that don't go blind with the brand. People go blindly with samsung I believe as I did the same. Because of branding the price of the phone is high but the features given within is not relevant to the price afforded. Seeing the unboxing videos of phone and initial reviews don't be a victim. Think wisely and go with a good one. People now a days are in serious mindset of non Chinese. But being with this mindset just like me I went with samsung(non Chinese) affording a high price but I didn't get a good phone for this price according to me. Because with this price I can get very good and high featured phone in other brands. I believe that brands like redmi, poco, vivo etc are born Chinese but now we have plants in India where we can get Made in India phones. And with this price range seriously a very good phone we can get and even I got as per my experience. I bought a POCO X2 phone a month ago with a lesser price than M31s and very much satisfied compared to M31s. Once again I seriously and sincerely suggest people, think wisely and go for good one.

      Lol, you said a month ago... you bought POCO X2 and from more than a month you are using M31s. What you did there? Comparing every feature between the two models?

    I am writing this review after a year of using Samsung M31s, it's very good phone with battery life really lasting long, fast charging and camera is really good. Face sensor has a little lag but overall it is value for money phone.
