Reviews


Highlights


1. 4K video recording
2. 6000 mAh battery
3. Super AMOLED display
4. 64 MP camera





Design


Let’s start with the design geeks. The phone is built with plastic material and available in blue and black colours. Though it has a 6000 mah battery, the mobile is sleek and not overweight to handle.



The right side of the M31 is filled with power and volume buttons, which are so solid and dense during clicks. At the top, there is one secondary noise cancellation mic that works well while making calls. The mobile supports 2 SIM + 1 SD (expandable up to 512 GB).



Like other Samsung modes, the bottom part is filled with a single speaker, type C charging port, and a 3.5mm jack. The fingerprint sensor at the back performs well, and its touch response is simply superb.




Display


The 6.4-inch display is made of corning gorilla glass 3 for protection, and the resolution of Galaxy M31 is set with FHD+ resolution. Samsung has the best unique display comparing with its competitors because of its super AMOLED display technology, which produces vibrant, solid, and punchy colours on the panel.



As the M31 is supported with Wide1 L1 certification, we need not get worried about streaming HD video contents across OTT platforms. Samsung’s Infinity “U” display waterdrop notch is comparatively small, and elegant offering some animations through light.



Overall, the display is so bright, vibrant and offers active colours during mobile usage and while playing videos.




Performance


Galaxy M31 has the lowest SAR value of 0.383 w/kg comparing with Samsung Galaxy M21 (review) and Samsung Galaxy A51 (review). Like other mid-range models, the M31 is built with Exynos 9611 processor which is a fitting processor in mid-range smartphones. And, it has Mali G72MP3 GPU to operate graphics parameters.



Samsung M31 runs on the Android 10 operating system skinned below One UI 2.0. Samsung must deserve applause for this latest aspect. Galaxy M31 has UFS 2.1 storage, and that is an upgraded one comparing with Samsung Galaxy A51 (review). The M31 is capable of multitasking, and you can play only light games with medium graphics.



If you are a gamer, then Samsung M31 is not built for you. Because you cannot play high-end games with high-resolution graphics with Exynos 9611. The refreshing rate of the display is only 60 Hz, which could be upgraded to the next level.




Camera


Samsung Galaxy M31 has a quad-camera setup --- The first 64MP primary with f 1.8 produces many details and does a satisfactory job. The shots in the primary camera won’t disappoint you for the given price. One noticeable minor negative aspect is the final image is seen over-sharpened when you zoom and notice it.



Samsung M31 produces above-average images when the dedicated night mode is ON. But, when the night mode is OFF, the 64MP primary camera gives a high range and perfect images at night. The next camera placed in 2nd place is 8MP ultra-wide, which produces good colors and perfect dynamic range.



This ultra-wide camera is capable of capturing shots at a 123-degree angle. The 5MP depth sensor camera is the unique among other companies. It performs its job well in splitting the subject well from the background and provides good background blur during portraits and the edge detection during the portrait is decent.



The final 5MP camera offers good and bright colours during macro shots. This macro camera does not have the autofocus mode which is a slight drawback. The 32MP selfie camera with f 2.0 produces 12MP output due to pixel binning technology. The HDR mode is absent in this camera. But capable of offering high and perfect skin tones and dynamic range.



The Edge detection in Galaxy M31 selfie camera is quite decent and does its job well. In Samsung Galaxy M31 we can record UHD 4K videos @30fps and 1080p @30fps mode. But the super steady stabilization mode is only available in 1080p mode not in 4K video recordings.




Battery


M31 has a big mega battery of 6000mAh, and yes, it’s a great treat for battery oriented users. But sadly, this brand has given only 15W fast charger, which takes more than 3.5 hours to reach 100%.



On comparing the battery with Samsung A51 (4000 mah battery), M31 is an excellent move in terms of battery. The 6000 mah battery is more than enough to perform multi-tasks for one full day.




Price


The price of Samsung Galaxy M31 is fixed at Rs.14,999/- for a 6GB / 64GB base variant and the upper variant is fixed at Rs.15,999/- with 6 GB / 128 GB. The brand has packed the M31 with more powerfu l features that match its price.



So the M31 model is worth buying to use and enjoy all its power-packed features.




Pros

  • 6000 mah battery

  • 64 MP camera

  • Pricing

  • Super AMOLED infinity “U” display

Cons


  • Not fitted to intense gamers who play high-resolution games.

Verdict

Samsung M31 is a perfect choice for your money. If you are not an intense gamer, then Samsung Galaxy M31 is just for you.
