Samsung galaxy m31 Super AMOLED Display
- 6.4 inches Super AMOLED
- 1080 x 2340 Resolution
- 19.5:9 Aspect Ratio
- 403 ppi
- 60Hz panel
- Corning Gorilla Glass 3
The Samsung Galaxy M31 has a 6.4 inch 1080×2340 (FHD+) AMOLED display. It’s a 60Hz panel with deep blacks and impressive color reproduction.
Following up on my initial impression, everything remains the same. The color is vivid and the contrast ratio is high. It’s perfect for YouTube, Netflix, and playing games.
The Always On Display is as usual. You can customize it to some level. You can also choose various color modes for display. If you like a more natural tone, you can opt for Natural mode, or else you can go with Vivid mode. You can also adjust the warmth and make the color temperature color or warm.
Samsung galaxy m31 Camera
Rear Camera: 64 MP, f/1.8, 26mm (wide), 1/1.72″, 0.8µm, PDAF8 MP, f/2.2, 12mm (ultrawide), 1/4.0″, 1.12µm
- 5 MP, f/2.4, 25mm (macro), 1/5.0″, 1.12µm
- 5 MP, f/2.2, (depth)
- Video: 4K@30fps, 1080p@30fps, gyro-EIS
Front Camera: 32 MP, f/2.0, 26mm (wide), 1/2.8″, 0.8µm
- Video: 4K@30fps, 1080p@30fps
To be frank, I’ve never been a huge fan of high megapixel sensors. I mean it’s great and all for capturing high details but I don’t really find it useful. After all, photos from our smartphones are only gonna end up on social media.
Samsung galaxy m31 Video
Samsung M31 supports 4k video recording but there’s no 60fps option even in 1080p. 4k videos are crisp with good details but you lose digital stabilization on 4k resulting in shaky videos. Stabilization improves greatly when you drop to 1080p but you lose slight details on 1080p.
The digital stabilization is not that impressive, you will see some warping as it tries to stabilize the footage. Now, it has a super steady feature at 1080p but what it does is, it actually captures video from the wide-angle camera and crops in slightly to give you stabilized videos.
This results in stabilized footage but details aren’t impressive since it is using the wide-angle camera.
Samsung galaxy m31 Performance
- Exynos 9611 (10nm)
- Octa-core (4×2.3 GHz Cortex-A73 & 4×1.7 GHz Cortex-A53)
- Mali-G72 MP3
- 28GB ROM 6GB RAM, 128GB ROM 8GB RAM, UFS 2.1
Samsung Galaxy M31 features the same chipset as the Samsung M30s; Exynos 9611. But it does have an option for a bigger 8GB RAM as it comes in two configurations: 6/128GB and 8/128GB.
Exynos 9611 is a fine chipset but it’s not the best performer in its price range as I’ve mentioned in my initial impression. It is made in a 10nm process and has Octa-core (4×2.3 GHz Cortex-A73 & 4×1.7 GHz Cortex-A53) CPU along with a Mali-G72 MP3 GPU.
Following up on my initial impression, I performed some benchmarks and played more games to test its actual performance. First, let’s look at the benchmarks.
Samsung galaxy m31 Software
Android 10, One UI 2.0
Samsung Galaxy M31 runs on One UI Core 2.0 on top of Android 10. I will say that One UI is one of the good UI out there. Personally, I like the Oxygen Os and I will say One UI is the 2nd best after it.
Samsung galaxy m31 Speaker
The speaker on the Samsung Galaxy M31 is quite loud given it only has a single speaker. Sound quality is nice, it feels thin if you play rock songs but it’s good for pop songs and videos. Speaker is good but it’s not excellent.
Samsung galaxy m31 Security
In terms of unlocking options, you can use the fingerprint sensor or face unlock but I prefer the fingerprint sensor. It’s quick and reliable but it’s now as quick as the Chinese competitors.
If you prefer, you can use face unlock as well. But, it’s not as quick as the fingerprint sensor. Also, it’s not consistent during low-light situations.
Samsung galaxy m31 Battery and Charging
Non-removable Li-Po 6000 mAh battery, Fast charging 15W
USB 2.0, Type-C 1.0 reversible connector, USB On-The-Go
Without andy doubt, Samsung M31’s 6000 mAh battery is monstrous.
On heavy usage, I was getting around 6-7 hours of screen on time even when I played games for more than 2 hours. And the thing is I would still have 30% battery left in the tank at the end of the day. Similarly, I would get 8 hours of screen on time on average usage.
Samsung galaxy m31 GeekBench
Starting off with GeekBench, a CPU benchmark. Exynos 9611 on the M31 does pretty well with a Single-Core score of 347 and a Multi-Core score of 1288. We compared it with Snapdragon 720G (Redmi Note 9 Pro), Snapdragon 665 (Realme 5i), and Snapdragon 675 (Redmi Note 7 Pro).
M31 does scores higher than Realme 5i in Single-core whereas Realme 5i does better in terms of Multi-core score.
Redmi Note 9 Pro is far ahead of M31 in terms of CPU performance.
Redmi Note 7 Pro is also ahead with good CPU scores.
According to this benchmark, Exynos 9611 on the Samsung M31 is right in between Snapdragon 665 and 675 in terms of performance. However, Redmi Note 9 Pro is far ahead.
Samsung galaxy m31 Should You Buy M31
Of course! It’s a very good phone.
Surely it doesn’t have any fancy features like a high refresh-rate display or even upper fast charging but it’s good where it needs to be. You’re getting the best AMOLED display you can get for the price.
Sure, performance is not the best for the price but it’s good enough, you can play high-end games without having to compromise. Its 64MP camera is also good in most situations. Then, you get an absolute monster of a battery.
But I do feel that Samsung should have done a better job with its build quality. Well, it feels robust and durable but the plastic back scratches easily and you have to very careful where you place it if you’re not using a case.
