The Samsung Galaxy M series has gained a lot of popularity thanks to affordable prices and up-to-date hardware. Samsung has managed to lower prices by selling these models online, reducing distribution costs. The sub-Rs. 15,000 Samsung Galaxy M30 set the pace, and a refreshed version, the Galaxy M30s, really helped the company strengthen its position in this segment. Samsung has now launched a successor to the Galaxy M30s, called the Galaxy M31. You now get a quad-camera setup, an upgrade from the triple camera setup on the M30s. However, the processor and the battery capacity remain unchanged. Will this be enough to keep the Galaxy M series competitive in the market? We review the Galaxy M31 to find out.

Samsung Galaxy M31 Summary

The Samsung Galaxy M31 sports a big 6.4-inch display and has a waterdrop notch at the top. It has thin bezels around the AMOLED display which helps it stand out among the competition. The Galaxy M31 is comfortable to hold in the hand but is a little heavy at 191g. The weight of the smartphone is mainly because of the big 6,000mAh battery that it packs.

Samsung has equipped the Galaxy M31 with an Exynos 9611 SoC and gets 6GB of RAM. It has two storage variants to choose from, 64GB and 128GB. The Galaxy M31 is a dual SIM device with support for 4G as well as VoLTE. It runs Samsung OneUI 2.0 on top of Android 10. We found the Galaxy M31 to have a fair amount of bloatware onboard.

The Galaxy M31 has a quad-camera setup at the back with the primary being a 64-megapixel shooter. It also houses an 8-megapixel ultra-wide-angle camera, a 5-megapixel macro camera and a 5-megapixel depth sensor. Daylight camera performance is good but low-light camera performance was disappointing.

  • Samsung needs to take it seriously now
    Productive (Jun 12, 2020) on Gadgets 360 Recommends
    I am a Samsung fan girl. I always used samsung phones as they gave quality. I and my cousin brother also buy Samsung but this time he purchased m31 of samsung for 15k and within 10 days he felt tht redmi note 9 pro was cheaper and better for 14k and sold me his Samsung m31 for 12k.As a buyer i realised where Samsung is loosing its market they carge more than redmi and realme but the M series is a straight competition 1)box does not come with back cover and m series needs it badly 2) processor =although i love samsung processor it has heating issues . It need to put to snapdragon to catch its market back 3)plastic back= phone gets lot of scattered and looses colour over time 4) pricing is too high Rest all makes it better than redme realme and all other chinese brands. Samsung plz change these stuff and get more productivity in the market its a really good brand but if this continues uall loose the market soon like nokia did. Save it although rest all stuff is really very good .

  • Camera worst
    Yogesh (Oct 11, 2020) on Gadgets 360
    I purchased Samsung M31 on 5th September from Amazon. Got delivered by 8th September Handset camara is not working it shows that camera failed since I purchased... Due to pendamic situation we won't be able to go to service center, before a week we went there and we have been told that it's our fault that camara is not working... So we requested to replace the handset. But service center people told that it's almost a month ago you purchased so it's not possible.. It's just due to lockdown we won't be able to come... Spending 19000 and have to use refurbished device.. It's hurting me.. If this is the scenario we will not go for Samsung device and will not recommend any one for Samsung. really fed up.

      It is not a fault of Samsung , I think, it is a great fault of Sender Shop & Amazon should be cautious.

  • Worst mobile of the segment
    Hema Kumar (Jul 29, 2020) on Gadgets 360
    Please don't go by their advertising. After using for 2 months I found this m31 is worst. It has no privacyand nocontrol over the apps, data consuming is more for more apps and other features And Am totally dissatisfied. It is better to go for any other product.

      What the control over the apps you are going to mean is not clear. Again No privacy means ?? I found no problem with this m31. Using for 3 months last.

    Himanshu Sharma (Jul 5, 2020) on Gadgets 360 Recommends
    I have taken samsung m31 yesterday, whenever I am making slow motion and super slow motion videos. It then begins to blink. The same problem is found for both A series and M series.

  • Value for money
    Sundara Pandiyan (May 11, 2020) on Gadgets 360 Recommends
    Really a good budget phone with big battery. Camera performance also awesome, but in pro mode there no control for shutter speed and while changing the iso i don't feel any differences. I need more update on camera modes. Phone performance and charging speed is good. Except camera modes i love this phone.

  • Worst Samsung phone ever
    Amrut Rajmane (Aug 7, 2020) on Gadgets 360
    I wish there was way to rate 0 star. Bought this phone as a gift to my sister couple of months back and the phone has been more with the dealer for repair than being used by my sis. First when we booted the phone there was an automatic software upgrade. Post upgrade the phone wouldn?t work. It would just hang. That was the first visit to the dealer. He did something handed over the phone back to us, in less than two weeks the touch screen stopped working. The dealer took almost 3 weeks to replace the screen owing to COVID logistics disruption. The phone came back to us a week back and now the phone has crashed again. The dealer is not ready to replace the phone as it is not as per Samsung policy. We are stuck with a horrible phone and Samsung wouldn?t care enough to do anything about this situation. A complete waste of time and money!
