2-minute Review [Positives]
  • Sleek, classy design - the Galaxy M31s seems identical to the Galaxy A51, with a glossy polycarbonate back design - giving it a premium look
  • The front gets a new trendy look with a hole-punch display, a first for the M-series
  • It has good ergonomics and feels comfortable to hold and operate
  • The side-mounted fingerprint scanner is quick to unlock the device
  • Vivid, crisp and punchy 6.5-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 Dark mode enabled
  • Samsung's OneUI is today one of the more clean, refined Android UIs that's especially well optimized for large displays like this one
  • 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 M31s' AMOLED display), and Always On Display option
  • Decent performance with the Exynos 9611 at the core (similar to Snapdragon 665) - the phone is good for basic operations
  • Good quad rear camera setup - 64MP main sensor + 12MP wide-angle lens + 5MP depth sensor + a 5MP macro camera
  • Shots taken with the primary camera during daylight are quite satisfactory, images are detailed, especially the 64MP shots, and they showcase the 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 single take is a nice addition from the more expensive S20 series, it lets you capture multiple formats at once
  • 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 M31s 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 25W fast charging - the phone takes around 2 hours to charge the battery completely, which is decent
  • Consider the Galaxy M31s for its vivid display, capable optics and stellar on-battery time
  • Xiaomi has gone big on the design front this time - the Redmi K20 Pro has a glass back with one of the most evocative gradient patterns you'll come across on any phone today - it's both premium to feel, and stunning to look at
  • The gradient effect that kicks in under the right lighting condition is quite mesmerising
  • The front is modern and sharp too, with a 'full screen' notch-less display (the selfie camera is a 'popup' one)
  • Decent in-screen fingerprint sensor - reasonably quick and reliable
  • Gorgeous, 6.39-inch Super AMOLED display - easily one of the best panels you'll find in this price segment - it has vibrant colors and excellent contrast levels, and sunlight readability is great as well
  • Of course, the lack of a cutout means you get an all-screen front, and the minimal bezels at the top and bottom create an immersive experience when playing games or viewing videos on the device
  • MIUI, especially with it's recent improvements continues to one of the better, more cohesive custom Android UIs around - and it's packed with features like gesture navigation, anti-flicker mode, reading mode, second space, dual apps, themes, etc
  • The K20 Pro also adds the POCO Launcher on top of MIUI - which brings the Dark Mode and App drawer to the K20 Pro
  • Xiaomi is also rolling out a Game Turbo feature that prioritizes bandwidth and mutes incoming notifications when you're in a game
  • Top-notch flagship performance with the top-notch Snapdragon 855 chipset at the core - the K20 Pro is expectedly a performance beast - and gets the highest Antutu scores of any Android phone at the moment
  • Very good triple rear camera setup - the phone has a 48MP primary camera backed by an 8MP telephoto lens and a 13MP wide-angle shooter
  • Image quality is great in all sorts of lighting conditions - they look crisp, vibrant, and details are captured well
  • The ultra-wide sensor and 2x telephoto lens also produce generally good results
  • The K20 Pro also comes with a dedicated night mode that does the usual multi-frame processing, and the results are pretty good - it gets more light in, and makes things sharper
  • Decent 20MP popup selfie camera, with a good portrait mode
  • Overall, the rear camera setup on the K20 Pro is the best for this price bracket, and matches up well to more expensive phones like the OnePlus 7 and Asus 6Z
  • Has a 3.5mm jack, that a lot of flagships these days tend to skimp on
  • Loud (single) downward firing speaker
  • Very good battery life with a 4000mAH battery - combine that with a very efficient 855 processor, and you will comfortably get 1.5 days of use
  • Fast charging support - up to a cool 27W (a 27W capacity charger will however need to be purchased separately for super fast charging - that said, Xiaomi does include a still-very-fast 18W charger in the box)
  • Xiaomi has again hit the ball out of the park with the Redmi K20 Pro, providing a still-excellent-value successor to the super successful Poco F1 - this is the cheapest price point at which you will get the flagship Snapdragon 855, along with all the latest features of 2019 - full screen, popup selfie camera, and in-display fingerprint sensor - people who attach more value to the software experience though might still want to spend a little more and go for the OnePlus 7 or Asus 6Z, for a cleaner experience
2-minute Review [Negatives]
  • The Galaxy M31s feels hefty at 9.3mm thickness and 203g weight (though, it's worth it for the 6000 mAh battery it packs)
  • However, it is an old chipset and heavy gaming and multi-tasking are taxing for the phone - the POCO X2 and the Realme 6 Pro are much better options that will handle gaming better than the Galaxy M31s
  • Look elsewhere if performance and gaming capabilities are your primary deciding factors - the phones like Realme 6 Pro and Redmi X2 are better equipped to meet your requirements in the performance segment
  • Face unlock mechanism is a little clunky - you have to first wake the screen and swipe up for the camera module to engage (this might get sorted via a software update though)
  • One issue with MIUI in recent times is the ads in the interface & notifications - those are still there (though a little less intrusive) - and while there are ways to disable them, it's a technical solution that a lot of prospective buyers will not be aware of
