2-minute Review [Positives]	Looks slick, and reflects off the same iridescent rainbow-like effects at the back as the Samsung Galaxy A50 when caught against light, only this one, comes with a prism-like pattern that Samsung calls a “3D prism design” - it's a head-turner no doubt And while the Samsung Galaxy A50s bears a polycarbonate body, it doesn’t look cheap and sports a very premium “glassy” look overall On the front is a sharp, modern panel with slim-bezels, and a U-shaped notch design (similar to Galaxy A50) Facial recognition to unlock your phone works well Beautiful 6.4-inch Full HD+ Infinity-U Super AMOLED display with a high 91.6% screen-to-body ratio, and Corning Gorilla Glass 3 for protection The screen looks sharp and bright, and being an AMOLED display, you will get deep black and vivid colors - sunlight legibility is also pretty good Samsung's One UI is now one of the better, more clean and streamlined Android UIs around, and is well optimised for modern large displays (like this one) Samsung has also added a Game Booster tool to the A50s to offer a better gaming experience Other features include an intuitive gesture-based navigation system, and an option to wake up Bixby using the power button Solid mid-range performance with the robust Samsung Exynos 9611 SoC (similar to Snapdragon 660 and Exynos 9610) - the experience is pleasant and smooth throughout including with games like PUBG Mobile and Asphalt 9 Good thermal management too - the phone doesn't warm up quickly despite extended game play Decent set of triple rear cameras for the price bracket - a 48MP primary camera with an f/2.0 aperture a second 5MP depth camera with f/2.2 aperture, and a third 8MP ultra-wide lens The quality of the pictures from the primary camera is quite good during daylight and outdoors - the A50s handles high-contrast scenes well and adds the right amount of detail and vibrance Night mode works reasonably ok for low-light situations and doesn’t add unnatural exposure to the scene Portrait mode ("Live focus") works well too especially when capturing outdoor daylight scenes Decent video recording performance with a dedicated 'super steady' mode which allows you to shoot decent “action” videos Decent 32MP selfie camera - in daylight outdoor lighting, selfies clicked turn out quite clear (not so much is low-light though) Overall, this is a fairly good camera setup for this price bracket (though not quite up to the level of the category leaders) Very good battery life with a 4000mAh battery - you will get about 1.5 days of use	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, a 8MP wide-angle lens, a 5MP depth sensor and 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 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
2-minute Review [Negatives]	The fingerprint sensor that sits beneath the display, is a tad bit slow The phone is a smudge-magnet, relatively easy to scratch, and also slippery (so you will want to use a case) This is however not the best performing phone in this price bracket - you will get better CPUs and stronger performance from Xiaomi and Realme phones The camera app is a little bit slow to launch and there is a small shutter lag when capturing photos As is right now the case with most mid-range phones, the wide-angle camera’s photos look fairly distorted, and details are soft Low light performance could have been better, across the board Volume levels of the speaker are a bit on the low side and could have been better - it's a little difficult to hear audio outdoors in a noisy environment Although the phone supports 15W fast charging, but it only includes a 10W standard (non fast) charger - it takes over 3 hours for A50s to go from 0% to 100% On the whole, the A50s, while a pretty decent phone by itself, will find the competition much more intense (than what its predecessor A50 faced) - unless you are a Samsung loyalist, you will want to look at the competition especially from the likes of Realme and Xiaomi	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
