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
  • Premium looks and design - with a beautiful, abstract geometric pattern on the back, and a smooth, metallic sheen - this is one of the hottest looking devices coming at this price point
  • Very easy to grip - the rounded sides and curved back panel make it fit comfortably in a palm
  • It is actually more compact than the Realme 5 - and you will not have any trouble using it even with one hand
  • The front is modern and sharp too - with a big 6.3-inch LCD screen, with a 'waterdrop notch' - and a 90.6 screen-to-body ratio - the chin is fairly prominent but the rest of the borders are narrow and modern-looking
  • The fingerprint sensor at the back, and face recognition - both work well, and are fast to unlock - and can be used to unlock not only the phone but also individual apps
  • Good, 6.3-inch full-HD+ IPS display - the screen can get quite bright and is easy to use outdoors - and video content looks good, with decent colours and sharpness
  • Support Widevine L1 DRM for high-res video streaming
  • ColorOS is now much more refined and streamlined than before - customisation options include a 'Smart Assistant' to the left of the first home screen, icon density on the home screens, UI animation speed, themes, and various gestures - you can long-press the phone's power button to call up Google Assistant, and launch apps with gestures on screen when the phone is in standby - and the standard Android navigation buttons can be replaced with a variety of gesture schemes
  • There are also no spammy ads in the interface - an issue that has recently plagued phones from Xiaomi
  • Excellent, top-bracket-for-the-price-range performance backed by the powerful Qualcomm Snapdragon 712 SoC which has a slight edge over the Snapdragon 710 and Snapdragon 660, which are commonly found in phones in this segment - everything from daily use to high-end games is smooth
  • Good quad camera setup at the rear - 48-megapixel primary + 8-megapixel wide-angle camera + 2-megapixel macro camera + 2-megapixel depth sensor
  • The primary camera especially delivers impressive photo quality in daylight - focus speed is fast - and the images are sharp, details are high, and the colour balance is good
  • Shots from the wide-angle and the macro camera, while not that that good in quality, give you some interesting shot framing options
  • Portrait shots utilize the depth sensor, and generally come out well
  • The 16MP selfie camera too delivers decent selfies, and also has a (decent) software-based portrait mode
  • Video recording quality is good too, especially in daytime - there's also electronic stabilisation, which works fairly well at 1080p
  • Nightscape mode works fairly well for night photography (though it takes several seconds for the phone to save a shot)
  • Overall, the camera setup on the Realme 5 Pro is easily among the best in this price bracket
  • The single speaker is quite loud and voices are clear even at high volumes (though of course, like most phones in this price bracket, there's no bass or depth when listening to music)
  • Good (though not exceptional) battery life with a 4035 mAh battery - you will get 1 day with heavy use, and 1.5 days with moderate use
  • Very fast charging with Oppo's proprietary VOOC quick charging technology - and a large 20W charger in the box with this phone - using the included charger, you will get up to 15 percent in 10 minutes and 70 percent in just over 30 minutes - pretty cool
  • The Realme 5 Pro looks like yet another winner from Realme, that once again sets the bar high for other competitors to try and match - it impresses across the board - and it should definitely be in your shortlist for this price bracket
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
  • There are still a number of pre-loaded apps however - though most of these can thankfully be uninstalled
  • The camera app looks slick but the layout is a bit awkward at times - for instance, to use the macro lens, you have to select the Ultra Macro mode which is buried in a spillover menu next to the standard Photo, Video, and Portrait mode selection buttons - this menu is unnecessarily small and you actually have to scroll down within it to find the Ultra Macro mode
