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 M51 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, similar to the Galaxy M31s
  • The phone feels solid in the hand - the 'glasstic back' offers better grip, and it is not as slippery as other phones with a glass back
  • The side-mounted fingerprint scanner is quick to unlock the device
  • Punchy, vivid and massive 6.7-inch FHD+ Super AMOLED display - the display is one of the best in class panels with great colour reproduction and viewing angles
  • 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 M51's AMOLED display), and Always On Display option
  • Very good performance from the Snapdragon 730G - the chipset and Samsung’s OneUI optimization could take anything that you throw at it, switching across apps, moving across the UI, multitasking, and opening multiple Chrome tabs, social media is a breeze - heavy games like Call of Duty run smoothly without any lag
  • Samsung has fixed the only major drawback it had in other M-series phones with average performance, and this time the Galaxy M51 has no issue taking on the competition in performance
  • Good quad rear camera setup - 64MP main sensor + 12MP wide-angle lens + 5MP depth sensor + a 5MP macro camera - the Galaxy M51 carries the same camera setup as seen on the Galaxy M31s
  • 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 mid-range 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 M51s are good for the price bracket, even though they are not the best
  • Mammoth, out of this world 7000mAh battery delivers an incredible 2-3 days of heavy usage easily, making the Galaxy M51 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
  • The Galaxy M51 brings very good value as its big battery, powerful cameras, and expansive display all help make a solid argument in the device's favour - the phone's Snapdragon 730G SoC also ensures that M51 offers enough in terms of raw power to help it tackle most things you throw at it
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 M51 feels hefty at 9.5mm thickness and 213g weight - it is difficult to use for a longer duration for calls, streaming, or even gaming
  • The back of the Galaxy M51 is a fingerprint magnet - it can also get scratched easily since it is plastic
  • The display lags with a 60 Hz display, where competing phones like OnePlus Nord offer higher 90 Hz refresh rate
  • There's still great competition at this price and the OnePlus Nord has a lot up its sleeve with a newer processor, higher refresh rate display, and a best in class software
