2-minute Review [Positives]
  • 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
  • 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 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
  • 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
