2-minute Review [Positives]
  • Simply stunning, premium glass design, especially with the Luminous Black option - easily one of the best-looking phones out there, at present (along with its predecessor the Reno 10x Zoom) - it offers a masterclass in how to craft a premium smartphone at a not-so-premium price point - in fact, half of the experience of the Reno 2 is in its looks and that's the part that satisfies you the most
  • The curved Gorilla Glass 5 rear panel is smooth and feels solid to the touch - the best thing about the back of the Reno 2 is that it is one seamless piece of glass without any camera bump - the vertical quad camera system sits underneath the glass, offering a clean and visually attractive look
  • The curved edges on the back also offer a nice grip
  • Much lighter and more manageable than the original Reno 10x Zoom
  • The iconic shark-fin rising selfie camera previously seen on the Reno 10x Zoom also returns on the Reno 2 (the pivot rising structure moves fast initially so that the camera is out in about 0.8 seconds, allowing you to unlock the phone using face scan quickly)
  • The on-screen fingerprint sensor is extremely snappy and slightly faster than the face unlock method, but both are equally reliable
  • Beautiful, bright 6.55-inch Dynamic AMOLED display - the screen-to-body ratio is 93.1, which means what you get is practically all screen and no bezels except for a very slim chin that is almost non-existent
  • The display itself looks spectacular with vivid colours, deep blacks and excellent viewing angles - brightness levels on the Reno 2 are fantastic as it can max out at 800 nits when outdoors, which is quite impressive
  • The display is also great for watching videos and playing games - the edge-to-edge display offers a distraction-free experience - the phone also supports the Widevine L1 standard so you can stream content on platforms like Netflix and Prime Video in HD
  • ColorOS continues to get more streamlined, and lighter, but still continues to offer some neat features such as a lockscreen magazine, Night Shield, Game Space and smart battery saving options
  • Very good performance backed by a 2.2GHz Snapdragon 730G processor (a slightly faster GPU compared to the Snapdragon 730) - the Reno 2 breezes through pretty much any task you throw at it, and is also an excellent smartphone to game on - even heavy games run consistently smooth
  • Excellent set of quad cameras - in addition to a 48-megapixel Sony IMX586 sensor that supports OIS and EIS, the Reno 2 also offers a 13-megapixel telephoto lens, an 8-megapixel wide-angle camera and a 2-megapixel monochrome lens
  • The Reno 2's telephoto lens can offer 5x hybrid zoom, which offers some really crisp and detailed zoomed shots with the help of EIS (it also offers up to 20x digital zoom, but that predictably leads to more soft, noisy images)
  • The 48MP main camera can take stunning shots in daylight via its default 12MP pixel binning mode - Photos look sharp and colourful, and when HDR kicks in the dynamic range can get pretty wide, offering good contrast in tricky lighting conditions - AI scene detection does well too
  • The Night Mode ('Ultra Dark mode') works reasonably well - this long-exposure mode requires you to keep your hands still for a few seconds, allowing you to capture brighter shots with low noise - though you shouldn't expect Pixel 3 level performance here
  • The wide-angle lens also comes in handy if you want a different perspective - it not only lets you capture a wide area, but you can also use it for close-up macro shots as well
  • The phone also holds up well in the video department with the ultra steady mode kicking in to offer good stabilisation
  • The Reno 2 can also capture live bokeh videos, which works pretty well - arguably better than even the Galaxy Note 10+
  • The 16-megapixel front camera will get you some nice-looking selfies in daylight (but not the sharpest or most-detailed) - and in addition to portrait stills, the selfie camera can also record real-time bokeh videos
  • Overall, the Reno 2 cameras are easily above par for this price bracket - and only a shade below the best cameraphones out there like the Pixel 3, and the Galaxy Note 10+
  • Good battery life with a 4000mAh battery and a 1080p screen - you can expect up to 1.5 days of use
  • Also comes with VOOC 3.0 fast charging support and a 20W charging brick in the box - charge the device for an hour, and you'll be good to go for the day
  • If you are not too picky about having the best raw performance for your buck, the Oppo 2 is an excellent, all-round flagship smartphone that especially impresses with its stunning looks and great cameras - if you do care about having the best performance however, you can look at the OnePlus 7, the Asus 6Z, or the Redmi K20 Pro
  • 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
2-minute Review [Negatives]
  • The glass however, is glossy this time around rather than matt finish, so expect to see some fingerprints and smudges as you go about your day, especially on the Luminous Black option
  • Having said that, it's not the fastest phone in the price bracket though, with Snapdragon 855 phones available at even lower price brackets (OnePlus 7, and Zenfone 6Z, for instance)
  • 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
