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
  • Top end flagship build quality - the Galaxy S20 is a fine piece of hardware that exudes quality and craftsmanship
  • The front looks absolutely gorgeous with an almost edge to edge screen and just a single punch-hole at the top centre - the front glass is slightly less curved along the side edges than previous S series phones
  • The phone is sealed tight and carries an IP68 rating, so you can accidentally dunk it in some water and it’ll survive
  • Ergonomically, the Galaxy S20 is the best of the lot with the most compact, easy to handle size
  • Stunning 6.2-inch Dynamic AMOLED screen that is the best you can buy on any phone right now - the sharpness of the display is simply outstanding with eye-popping clarity
  • The 120Hz refresh rate gives the screen a luscious smoothness that has to be seen to be believed, you’ve got a screen that simply dominates every other panel on the market
  • The screen is also HDR10+ certified, which means the right content will deliver incredible dynamic range - the HDR10 movies on Netflix look really impressive
  • Running the Galaxy S20 is Samsung's OneUI 2 on Android 10 - which, as far as Android UIs go, is one of the most refined, well thought-out experiences
  • Powering the Galaxy S20 is the Samsung's own Exynos 990, which is one of the best CPUs available in the market, just a shade behind the Apple's A13 - the phone feels fast all the time, no matter what content or app you throw at the S20, it devours the calculations and offers buttery smooth performance
  • Samsung gave the Galaxy S20 an impressive triple-camera system on the rear - the standard lens boasts a 12MP sensor, joined by an ultra wide-angle 12MP camera, and an optical telephoto 64MP camera
  • The primary 12MP camera gives you crisp detailed images with the good dynamic range that Samsung’s cameras are known for and the colours are wonderful
  • 64MP telephoto lens is capable of 3x lossless zoom and up to 30x digital zoom - the Galaxy S20's mix of sophisticated hardware and software deliver a precise images that are much clearer than anything else in the market (the 100x zoom is not present in the S20 and S20 Plus)
  • The Galaxy S20's 12MP Ultra-wide lens churns out exceptional results, delivering eye-catching shots, even in challenging lighting conditions
  • The low-light shots turn impressive, even in incredibly dark situations, the clarity is quite impressive, and the colours are perfect with little noise - the night mode further improves the quality with brighter and colourful images (though, the Pixel and iPhones still do a slightly better job in low light)
  • The most standout camera feature on the S20 is Single Take mode - when engaged, Single Take records a 10-second video and snaps multiple images, giving you an entire gallery of options to choose from and share
  • Video recording with the phone looks amazing - it’s sharp, colourful, properly exposed, and on-point when it comes to white balance - video also supports live focus mode, this uses the ToF camera to help judge depth and create a portrait-like effect when capturing video - it is also capable of capturing 8K videos (though, the use case for 8K is very limited)
  • The Galaxy S20 has improved ten-fold in Live Focus mode - it captures very realistic photos and is a massive step up from the portrait mode in Samsung’s prior phones (though, iPhone 11 series is still the champ in portrait shots)
  • The 10MP selfie camera does a fine job - you get a clear view of your pores in good light, and the target resolution dips in low light to keep images clean and bright
  • A pair of USB-C headphones is included in the box
  • Very good stereo speakers
  • Good battery life with the 4000 mAh cell - you will get a comfortable one day of use with heavy to moderate use
  • Sufficient fast charging with the supplied 25W charger - it boosts the battery by 50% after just 27 minutes
  • Also supports 15W wireless charging, and it can fill the battery to 50% in just 35 minutes on a charging pad
  • It also supports wireless reverse charging and can charge other phones or accessories that support wireless charging
  • The Galaxy S20 has a gorgeous screen, classy hardware, wicked performance, good battery life, and capable cameras, and the Samsung's name - if that's what you're looking for, go buy it
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
  • The in-display fingerprint sensor is unreliable - it’s slower than other sensors on competition and far less accurate
  • Aesthetically, the Galaxy S20 looks dull, there's no flair in the design, like the Aura Glow option Samsung introduced last year, which looked fascinating - the huge camera module doesn't help either
  • Overall, while Samsung has created flagship lever cameras that compete at the top level and comes out as champs in many situations, they are still slightly behind the iPhone cameras, that are more consistent
