2-minute Review [Positives]
  • 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
  • The design feels fresh and vibrant - phone's sleek profile is eye-catching, with a matte back glass, it is one of the nicest looking phones for the price
  • The phone looks quite flawless from the back, it features a rather flashy back cover
  • The Vivo V20 is one of the lightest around in the price segment, and at 7.38mm in thickness, it is surprisingly slim
  • The power button has a texture to give it a more distinguished feeling
  • The in-display fingerprint scanner, as well as face recognition, are quick to unlock the V20
  • The display is a gorgeous 6.44-inch AMOLED FHD+ panel which promises vibrant and life-like colours - the contrast is impressive and it also supports HDR10 for high-quality video playback
  • It gets bright enough for using the device even under harsh sunlight
  • The Vivo V20 comes with Android 11 out of the box, with Vivo's new Funtouch OS 11 - this new skin by Vivo brings several bells and whistles, and a much cleaner, simpler interface - there's an improved dark mode and tons of customisation options
  • Good performance from the Snapdragon 720G SoC - it is good enough to help you through tasks of daily use and even running multiple apps simultaneously - casual gaming is no issue and heavy games run at medium settings, which is decent
  • Good triple cameras for the price - a 64MP primary camera, an 8MP ultra-wide-angle camera, and a 2MP mono camera
  • Photos shot in bright sunny conditions turned out well - images clicked using the device generally come out with life-like colours and packing good detail
  • The Ultra-wide camera adds fun new perspectives, it can take dramatic super-wide-angle photos with lesser details than the main camera - besides, it can also take Macro shots, which come out with good detail, and you end up with a higher resolution image compared to what most dedicated macro cameras produce
  • Portraits have good edge detection and you do get the option to set the intensity of the blur effect - beautification is enabled by default which smoothens skin textures
  • Low-light camera performance is good, photos have little noise and details in brighter areas are decent - enabling Night mode improves the level of detail
  • The 44MP selfie camera is very good at what it does - daylight selfies are sharp with accurate colours and good details, there's also an Eye Autofocus option that keeps the subject in sharp focus - portrait selfies are possible and you can set the level of blur before taking a shot
  • Video recording in daylight is good, video recording tops out at 4K for the primary as well as the selfie shooter - footage shot in 4K, as well as 1080p, is stabilised (though, video shot in low light has a shimmer effect at both resolutions, which isn't good)
  • Overall, cameras are one of the highlights of the phone and they can take on any other capable camera phone at this price
  • Good battery life from the 4000 mAh battery - it can easily manage to keep the phone going on for around a day on moderate-heavy use
  • Charging is quick with the supplied 33W FlashCharge charger - it takes the V20 to 98 percent in an hour
  • If you value looks over other aspects, the Vivo V20 will appeal to you, it is well designed and feels premium to the touch - the device also offers above par photography performance, it emerges as a very good option for taking pictures and shooting videos
2-minute Review [Negatives]
  • 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
  • Because of its slim profile, the Vivo V20 is a bit slippery
  • Though, it isn't a high-refresh-rate panel
  • However, this isn't the best performing phone at the price, there are better options available like the OnePlus Nord
  • However, if heavy-duty gaming is what you're looking for, alternatives such as the OnePlus Nord offer significantly better performance, you can also consider the Galaxy M51 for its insane battery life powered by a 7000 mAh battery
