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
  • Shiny, premium design - the back panel features a dual-tone gradient texture, which shifts shade depending on the angle light hits it
  • The front looks similar to the V20, with its narrow bezels and a small dew-drop notch
  • The smartphone is thin and the weight is easily manageable - and the curved sides make the phone comfortable to hold and carry around
  • The in-display fingerprint scanner as well as face recognition is quick to unlock the Vivo V20 SE
  • The display is a gorgeous 6.44-inch AMOLED FHD+ panel which promises vibrant and life-like colours, similar to the Vivo V20 - the display has good viewing angles and gets bright enough when outdoors
  • The Vivo V20 SE comes with Android 10 out of the box with Vivo's new Funtouch OS 11 and not Android 11 like on the elder sibling, but Vivo has promised the update to 11 at the time of launch, - this new skin by Vivo brings several bells and whistles, and a much cleaner, simpler interface - there's an improved dark mode and ton of customisation option
  • Good triple rear camera setup - a 48MP primary camera, an 8MP ultra-wide-angle camera that is also capable of macro photography, and a 2MP depth sensor
  • In daylight, the Vivo V20 SE manage decent shots with good details on objects even at a distance - while shooting outdoors in bright conditions, the V20 SE is quick to enable HDR
  • The ultra-wide-angle camera offers a wider field of view but at the cost of details - the images aren't as sharp as the primary camera, but they fit a lot more scene into the picture - Close-ups with this camera turn out well, and the phone manages to capture sharp images, this is much better than the dedicated low-resolution sensors
  • Portrait shots with steady subjects turn out well, with good edge detection
  • The V20 SE manage good selfies in daylight as well as low light - you can take portrait shots using the selfie camera, and the V20 SE blurs out the background automatically
  • Battery life on the V20 SE is good from the 4100 mAh battery, and the phone goes on for a day and a half on a single charge
  • Charging is also quick with the 33W charger bundled in the box - the device gets to about 96 per cent in an hour
  • The V20 SE is a good phone that has a few things going for it - the device offers a lightweight design and decent cameras for the price
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 glossy finish at the back is prone to fingerprints and smudges
  • The panel lacks support for fast refresh rate
  • Average performance from the Snapdragon 665 - this isn't the most powerful chipset for the price, it is available on phones at half the price, the competitors like the Poco X3 offer much better performance for this segment
  • Low-light camera performance is average overall - photos appear smooth and objects at a distance have a watercolour-like effect - enabling Night Mode results in slightly brighter images, but nothing game-changing
  • On the other hand, if you are looking for a well-rounded smartphone, the V20 SE isn't your best bet - it sports a weaker processor, which is evident when playing heavy games, in this case, the Realme 7 Pro and the Poco X3 would be suitable alternatives
