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
  • Slick, trendy design - with a punch-hole front camera, which is one of the smaller ones on a phone to date
  • The good bit is despite sporting the four cameras, the back panel of the V17 doesn’t look cluttered - the rectangular (vertically) quad-camera module on the top left corner of the back adds to the overall design
  • Amazingly lightweight, for a phone with 4500 mAh battery inside
  • Despite having the same screen size as the V17 Pro model, it very easy to use with just one hand - which was difficult with the V17 Pro
  • Both the in-display fingerprint sensor & Face Unlock are fast and unlock the smartphone quickly
  • Beautiful 6.44-inch, Super AMOLED display with a punch-hole, which gives it an amazing screen-to-body of 91.38 per cent - it’s a delight watching videos on the Vivo V17
  • The full-screen display also get pretty bright in all lighting conditions, exhibits very good viewing angles and punchy colours
  • The Vivo V17 also comes with an always-on display option, which is useful
  • Solid performance with the Snapdragon 675 at the core - every-day use to gaming - it’s all lag-free
  • Good quad-rear camera setup (48MP main camera + 8MP ultra-wide camera + 2MP macro camera + 2MP depth sensor)
  • Pictures shot in bright daylight show a good amount of details and decent colours - Vivo V17 doesn’t pop the colours too much and captures the right colour-shade
  • The ultra-wide-angle lens offers a new perspective - shots look decent (though they are less detailed)
  • The portrait shots also turn out to be good, but the edge detection could have been better
  • Super Macro camera mode shows great details and good colours - the macro mode works best in good lighting conditions
  • The low-light pictures with the V17 turn out well - the Night camera mode of the V17 especially captures better details and colours in low-light conditions compared to the default photo mode
  • The 32MP front camera on the Vivo V17 clicks great selfies in good light
  • The night mode also works for the front camera and again it works pretty well
  • Very good battery life with a large 4500mAh battery - you will easily get about 1.5 days of moderate use
  • 18W fast charging support: it takes around 1.5 hours (approx) to charge the V17 fully with its bundled charger
  • Overall, the V17 is reasonably good value - especially if camera and design are your primary priorities, the Vivo V17 is a solid choice to consider in the under 30k segment - it does well on both those parameters
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
  • The Software continues to be a relatively weak point for Vivo, with a cluttered Funtouch UI (though it is quite feature-packed)
  • This is certainly not the best performing phone of this price bracket though - you get a much more powerful Snapdragon 730 with the Redmi K20 - in fact, there are the Vivo Z1 Pro and the Vivo Z1X that again cost less and come with a newer Snapdragon 712
  • Low light video though, is below average
  • If you are looking for an all-rounder though, you will have better options around especially in terms of software & performance - you will want to look at the likes of Realme XT, and Redmi K20
