2-minute Review [Positives]
  • Excellent, premium, 'dreamy' new design, with high quality materials and top-notch build quality - the frosted glass at the back just adds a new dimension to not just the visual appeal but also the in-hand feel
  • The front has a smaller teardrop notch than the OnePlus 7
  • A bit smaller than the OnePlus 7 Pro and slightly easier to hold (it's still on the large side though on absolute scale, so if you don't like big phones, you might want to reconsider)
  • Basic water resistance (though it's not IP rated)
  • Snappy in-display fingerprint scanner
  • Gorgeous, super smooth 90Hz AMOLED display - along with the display on the OnePlus 7 Pro, this is one of the most amazing displays out there on any smartphone - you will enjoy how much zippier and smoother the phone feels scrolling through things like web pages and apps
  • Strong brightness and great sunlight legibility
  • This time it's also a flat screen without the curved edges of the OnePlus 7 Pro - while that makes it look perhaps less stunning, it's a more practical design from a usability point of view
  • OnePlus continues to have one of the most refined, butter-smooth, minimalistic (nearly stock), yet very useful Android skins, with some handy off-screen gestures, smart customization options, an excellent and improved 'Reading' mode, and Zen Mode to control your phone usage - the excellent software experience remains one of the primary reasons to consider a OnePlus phone
  • Breakneck speeds with the new Snapdragon 855 Plus (which is supposed to be about 15% faster than 855 with graphics), and fast UFS 3.0 storage
  • Playing graphic-intensive games is smooth, and the phone is lightning quick at launching and quitting apps, surfing the web and taking photos
  • Good, versatile, triple rear camera setup, almost identical to the OnePlus 7 Pro - the only significant difference is that the telephoto lens, while packing more pixels (12MP vs 8MP on the 7 Pro), lacks OIS, and has up only to 2x zoom (instead of 3x on the 7 Pro)
  • What that means is that picture & video quality is also very similar to the OnePlus 7 Pro - in daylight, the photos are clear, bright and vibrant with some very good HDR rendering - in low light too, the performance is more than decent, and the Night mode helps with that
  • The wide-angle camera takes bright and sharp landscape photos, and the pictures don't show much warping around the corners, as wide-angle cameras tend to do
  • The new macro mode is good too - allowing you to take pictures of objects closer and with much more in focus than before
  • Portrait shots are also great - the fallout between the foreground and background looks smooth and natural, and you can now take portrait photos with the wide-angle camera as well
  • The 16MP front camera is good too - again similar to the 16MP front camera on the OnePlus 7 Pro
  • Uses its earpiece as a speaker, which gives the OP7T an excellent stereo audio setup - it's even slightly louder than the 7 Pro - and one of the best stereo audio setups on a current smartphone
  • Good battery life with a 3800mAh battery, and a 1080p screen - you will comfortably get a day's use, even with the 90Hz display
  • Amazingly fast charging with the new Warp Charge 30T technology - it charges to 34% in 15 min, and 68% in 30 min
  • On the whole, the OnePlus 7T is an excellent, top-grade addition to OnePlus' tradition of providing top-grade flagship devices at surprisingly reasonable prices - arguably its best value device in recent times - it's again the new 'budget flagship' to beat - near perfect
  • Between this and the OnePlus 7 Pro, it will be mostly down to whether you value the curved screen and the pop-up selfie camera enough to pay the extra moolah - for most people, the OnePlus 7T will be the more sensible value choice
  • 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 camera bump at the back may be an eyesore for some (it's subjective though)
  • It's a very competent camera setup for the price, but again it's not quite up to the level of the most expensive flagships like the Galaxy S10 series, Galaxy Note 10 series, Pixel 3 series, or the iPhone 11 series
  • No included earbuds or a 3.5mm headphone adapter
  • If you want to look at even lesser expensive budget flagships though, you do have some strong options now - the two best value ones would be the Asus 6Z, and the Redmi K20 Pro - though you will be missing out on the super smooth 90Hz display and the great software experience of OxygenOS
  • 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
