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
  • Attractive, eye-catching glossy plastic rear panel with a beautiful multi-coloured gradient finish, that catches the light as you tilt the phone around
  • The front is sharp and modern with a 6.54-inch Full HD+ display, thin bezels, and a punch-hole camera on the top-left corner of the display
  • On the whole, the Z1 Pro is arguably the best designed phone of this price segment
  • Has a handy dedicated Google Assistant button
  • Large, sharp Full HD+ display, with good viewing angles, and sunlight legibility - you get an immersive experience while watching videos, playing games and consuming other multimedia content on it
  • Vivo's Funtouch OS UI is fairly feature packed, and aesthetically is similar to iOS
  • There is also now a ‘Dark Mode’ feature that turns almost all the popular apps dark
  • The Vivo Z1 Pro also has a gaming assistant and mode rolled into one called Game Cube - it offers functions like blocking background calls, blocking notifications, reject calls during gaming, turning on Esports Mode and other things
  • Excellent, class-leading performance with the new Qualcomm Snapdragon 712 processor - you will get snappy performance all-round, and even high-end games will run effortlessly in their 'high graphics' settings
  • The smartphone also has good temperature control, so even with long times of gaming, there isn't much heating up
  • Good set of triple rear cameras (16-megapixel primary camera + 8-megapixel ultra-wide camera + 2-megapixel depth sensor)
  • You get some pretty detailed photos in most lighting conditions - the color reproduction and balancing is quite accurate as well
  • On the front, it comes with a excellent 32-megapixel snapper, which again does very well with details
  • Overall, this is a good camera setup for the price bracket, and only a bit behind the top cameras of the Redmi Note 7 Pro, and the Realme 3 Pro
  • Excellent battery life, with a huge 5000mAh battery - you will get a comfortable 2 days even with heavier use
  • Fast charging support - the device goes from 0 to 100% in 2 hours - which is pretty decent for the battery size
  • The Z1 Pro looks like a smart winner from the Vivo camp, with hardly any flaws, and an excellent performance to price ratio - if you value performance in a phone, or are into gaming, this is the mid-range phone to get - if you are looking for the best possible cameras instead, then the Redmi Note 7 Pro, and Realme 3 Pro have a slight advantage
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
  • On the heavy and bulky side (thanks to the large battery it packs)
  • The display does not have a Widevine L1 certification - as a result, you can stream videos available on the over-the-top platforms such as Netflix and Amazon Prime Videos at a maximum resolution of only 480p — not HD or fullHD
  • For people who like a stock Android interface though, Funtouch OS may not be to their taste (once again, it's more iOS like in its aesthetic, and also packs some bloatware)

  10. Despite being good enough for now, the Galaxy M31 just doesn’t enthuse the kind of confidence that would see it being considered in the same breath as more powerful devices from Redmi and Realme
