2-Minute Review

Let's cut through the noise, and get to the crux of it. 4 Expert Reviews analysed and summarised by the PhoneCurry Editorial Team, in a short and sweet 2-minute review.

Design

  • 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
  • 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

Display

  • 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

Software

  • 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
  • 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)

Performance

  • 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

Camera

  • 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
  • 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

Audio

  • Decent bottom-firing speaker - sufficient for personal listening

Battery

  • 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)

Verdict

  • 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

  1. The A31 can stand on its own as a decent mid-ranger... but the competition is just brutal

  3. The Samsung Galaxy A31 is a decent smartphone... but it is facing competition in-house only, its M-series sibling the Galaxy M31 is a better and much affordable option
