| 2-minute Review [Positives] |
- Decent looks, similar rainbow-like effects at the back as other Galaxy A series phone when caught against the light, and a prism-like pattern that Samsung calls a “3D prism design” - the design is been overused by Samsung
- While it supports a polycarbonate back, it still manages to look premium
- Compact and light for the display size and battery capacity, at just 185g, and 8.6mm in thickness
- Sharp, bright 6.4-inches Super AMOLED panel with a full-HD+ resolution - its vivid colours make it a joy to stream content, while games also look great on the panel because of its high colour accuracy
- There's Widevine L1 support by default, which makes streaming content in HD possible
- Comes with Android 10 out of the box - Samsung's One UI 2 is now one of the better, more clean and streamlined Android UIs around, and is well optimised for modern large displays (like this one)
- Samsung has also added some neat features including a Game Booster and an intuitive gesture-based navigation system
- Decent quad camera setup at the back - a 48MP primary sensor + 8MP wide-angle camera + 5MP macro camera + 5MP depth sensor
- Under good light, the Galaxy A31's primary camera manage to capture detailed shots with good dynamic range - images are reasonably sharp, noise is also competently removed, colours are generally nice, and the phone strikes a good balance with saturation
- The ultra wide-angle cam is decent at capturing more scene in the image (though, the quality is lower than the main camer)
- Macro camera turns out quite good close ups - you can get a lot closer to your subject when using the macro camera and the sensor picks up a fair bit of detail
- Very good portrait mode ("Live focus") - image quality is good and the depth camera helps the Galaxy A51 do a decent job of edge detection
- Photos from the 20MP front camera looks very impressive - selfies have plenty of detail and look really sharp, colors are pleasing, the dynamic range is impressive for a selfie camera - Selfie portraits are a thing on the A31 and surprisingly impressive - subject separation with a single camera is hard to pull off, and Samsung has done a great job of it
- Decent bottom-firing speaker - sufficient for personal listening
- Good battery life from the 5000 mah battery - easily able to go well beyond a day on a single charge
- Reasonable 15W fast charging - charges 67 percent in an hour (though, not as quick as others in this segment such as the Redmi K20 Pro)
|
- Decent looks and build quality - very similar to the Samsung Galaxy M30s, with a a unibody polycarbonate design, and glossy finish on the back panel - the only major difference is the camera module which now packs a fourth camera
- The plastic body keeps the phone feeling relatively lightweight at 191 grams, which is mighty impressive for a phone packing a big 6000 mAh battery
- It also feels great to hold with a seamless curved panel that meets the display up front
- Modern, Infinity-U front - bezels around the screen are slim, except for a slightly thick chin - you still get around 90 per cent screen-to-body ratio, which is great
- Fingerprint sensor at the back is easy to reach
- Gorgeous, 6.4-inch FHD+ Super AMOLED display with excellent viewing angles, and brightness levels - easily one of the best displays in the price bracket
- It also comes with "Widevine L1" certification, which helps stream content in crisp HD resolution
- Blacks are deep on the AMOLED display, which looks good with Night mode enabled
- Samsung's OneUI is today one of the more clean, refined Android UIs that's especially well optimised for large displays like this
- One UI also brings in other useful stuff, like a System-wide Dark mode (which turns the background completely black, and looks great on the M30s' AMOLED display), and Always On Display option
- Decent performance with the Exynos 9611 at the core (similar to Snapdragon 665) - the device is fairly quick to load up apps - multitasking is a breeze
- Good quad rear camera setup - 64MP main sensor + 8MP wide-angle lens + 5MP depth sensor
- Shots taken with the primary camera during daylight are quite satisfactory, images are detailed, especially the 64MP shots, and they showcase good dynamic range
- The ultra-wide sensor, like on any budget phone, is a good addition - it takes social media-worthy images in great lighting conditions (in low-light, the quality dips and pictures look grainy and noisy, wide-angle shots also have barrel distortion at the edges)
- Photos taken in low-light looks good - switching to Night mode helps reduce grain in the output and further improves image quality
- Live Focus shots are quite impeccable and the camera app does give you the option to set the level of blur before taking a shot - edge detection is very good and the Galaxy M31 does a good job of separating the subject from the background
- The macro camera takes decent shots outdoors (though, the quality dips when indoors and the output is restricted to 5MP in resolution)
- The 32MP selfie camera is quite good and takes detailed selfies (though, in low light, the quality goes down a notch and results are grainy)
- Overall, the cameras on the M30s are good for the price bracket, even though they are not the best (that title crowned to the POCO X2)
- Monster 6000mAh battery delivers an incredible 2-3 days of usage easily, making for one of the largest battery life smartphones currently available
- Supports 15W fast charging
- Samsung has seen success with the Galaxy M30s, so it didn't want to fix what isn't broken, they upgraded the RAM, put in a fourth rear camera, and preloaded Android 10 - if you don't care for benchmark scores and just want a device that covers the basics and has great AMOLED display, has great battery backup and has a versatile set of cameras, the Galaxy M31 will do just fine

| 2-minute Review [Negatives] |
- The front has some thick bezels for the price
- The in-display fingerprint sensor, as well as the facial recognition, are on the slower side
- The glossy body is prone to picking up fingerprints
- There's still some bloatware pre-installed, including third-party apps and some of Samsung's own apps such as Samsung Shop (though most of them can be uninstalled)
- Average performance from the MediaTek Helio P65 - it feels a bit sluggish overall, there's a persistent hint of stutter in the animations, and lag when switching between apps
- No video stabilisation - video results are just average
- Low light photos out of the Galaxy A31 aren't great - the main camera's output is soft and noisy, while the colors are relatively desaturated
- Overall, while the Galaxy A51 offers good cameras, there are certainly better options available, such as the Redmi K20 Pro
- The Galaxy A31 has hardly anything going for it - the middling SoC performance and underwhelming cameras do nothing to help, there are better options available from Xiaomi and Realme
|
- The power button and volumes are quite flush with the frame which means they lack that tactile, clicky feel
- Design feels a bit dated and underwhelming, there is no spark in Galaxy M31's design as we see in other brand's phones like Xiaomi and Realme
- However, this is an old chipset and heavy gaming isn't best on this phone - the Redmi Note 8 Pro, the POCO X2 and the Realme XT are much better options that will handle gaming better than the Galaxy M31
- Samsung Galaxy M31 falls behind in fast charging as competitors are offering close to 30W fast charging, the 15W on M31 feels low
- Having said that, the Redmi Note 8 Pro and the Realme X2 will still offer you more bang for your buck overall and when it comes to intensive tasks like gaming, you’ll be better off choosing the POCO X2 or the Redmi Note 8 Pro that are probably the best phones for gaming in this segment
