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
  • Beautiful, sleek design with a silver finish that switches colours as per angled light
  • The front is sharp and trendy with a pill-shaped punch-hole on the top-right that has the two front-facing cameras
  • The in-display fingerprint scanner is quick
  • Vivid, crisp 6.44-inch AMOLED display with a Full-HD+ resolution - the display looks punchy and you can tweak the display colour mode as well as the colour temperature
  • Vivo claims the peak brightness of 1200 nits, which makes it a comfortable screen to look at even in direct sunlight
  • Decent performance from the Snapdragon 712 SOC - casual and day-to-day applications run fine without any issues
  • Good quad-camera setup - a 48MP primary camera, an 8MP ultra-wide camera, a 2MP macro camera, and a 2MP depth sensor
  • In daylight, the primary camera manages good shots with ample detail, objects at a distance are visible on zooming in
  • The ultra-wide-angle gives a fun, wider perspective to images (though, the details aren't as good as the primary camera)
  • The portrait mode works well and it lets you select the level of blur before taking a shot - edge detection is good in well-lit conditions
  • In low light, the phone takes decent photos - the night mode makes the scene brighter and objects in the shadows more recognisable (though, it's a little slow and forces you to hold the camera still)
  • The 32MP selfie camera is capable of delivering some very good selfies that are sharp and detailed - There is also an 8MP ultra-wide sensor that lets you take wide selfies and fit more subjects or people into one shot
  • Very good battery life with the 4500 mAh battery - it can manage about a day and a half worth of use out of the battery in one charging cycle
  • Charging is quick, and the phone manages to charge to 83 per cent in an hour
  • The Vivo V19 is a good camera phone which nails the basics with a trendy design, crisp AMOLED display and very good battery with fast charging
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
  • The Software continues to be a relatively weak point for Vivo, with a cluttered Funtouch UI - there's also plenty of bloatware (though it is quite feature-packed)
  • However, this processor is commonly found in smartphones priced at around Rs. 15, 000 and phones such as the Realme X2 Pro feel faster because of the better processor
  • The macro camera is just average and the output is restricted to 2-megapixels only
  • However, this is not the best all-rounder and the choice of processor for this price is a bit disappointing, when phones like the Realme X2 Pro and Redmi K20 Pro offer very good performance for the price and are better all-round phones
