Our Opinion

The OnePlus 8 Pro (8GB RAM, 128GB) is a significantly better phone, but the Samsung Galaxy M51 (8GB RAM) is significantly better value for money. Which phone should you buy? Depends on how much you want to spend! But if budget is not a constraint then we recommend the OnePlus 8 Pro (8GB RAM, 128GB)

2-minute Review [Positives]
  • Gorgeous, premium design - the OnePlus 8 Pro uses a familiar soft-touch glass back, and an aluminium frame - the OnePlus 8 Pro shares the same core design ethos as the OnePlus 7 Pro
  • On the front is a beautiful edge-to-edge display and a hole-punch selfie camera
  • OnePlus's handy alert slider is still here, which enables you to quickly switch between silent, vibrate and sound-on modes
  • With a rating of IP68, the OnePlus 8 Pro is protected against total dust ingress and submersion in up to one meter of water for 30 minutes
  • The in-display fingerprint reader is quite accurate and works quickly
  • A gorgeous 6.78-inch, QHD+ screen, with excellent viewing angles and what looks like spot-on colour reproduction - the display offers an industry-leading 1300 nits peak brightness
  • OnePlus has bumped up the refresh rate to 120 Hz which results in smooth scrolling in apps, and better graphical fluidity in games, overall providing a more premium experience - you can even use the 120 Hz at QHD+ resolution, unlike it's Samsung counterpart
  • When it comes to video playback, content can be enhanced further with two additional settings - 'Vibrant colour effect pro' optimises the colours and contrast in videos to provide a more vibrant picture - 'Motion graphics smoothing' increases the frame rate of the video for clearer and more smooth playback
  • Overall, the OnePlus 8 Pro display is one of the best on a smartphone, at present
  • OxygenOS continues to be one of the most thoughtfully-designed, clean (stock-like) UIs for Android with a host of additional customisation
  • Blistering performance from the Qualcomm's top-of-the-line Snapdragon 865 chipset - with its 120Hz display, highly-optimised OxygenOS software, and plenty of under-the-hood tweaks, the OnePlus 8 Pro feels like the fastest phone around
  • Excellent quad-camera setup - consisting of a 48MP primary camera, a 48MP ultra-wide lens, an 8MP telephoto lens and a 5MP colour filter sensor
  • Shots taken with the primary camera are sharp and well-exposed with plenty of details, dynamic range is quite good with true-to-life colours, and white balance is consistent with the scene
  • The ultra-wide camera takes great shots as well, it pulls double duty and can shoot close-up macro photos as well - images shot with the ultra-wide lens have good details
  • Image quality from the telephoto camera is pretty good, colours and white balance are mostly consistent with the other cameras - it lets you zoom up to 3x optically and 30x with a mix of digital zoom
  • "Color filter camera" produces interesting images with its photo-chrome filter over the sensor (though, it feels more like a gimmick that normal people will hardly use)
  • Lowlight performance is quite good and the ultra-wide camera can also be used to shoot Nightscape photos
  • Portraits look pretty good, and the subject separation is on point - the portrait effect is quite convincing with smooth and silky bokeh around the subject
  • The 16MP selfie camera is the same one used in the OnePlus 7 Pro - it takes great-looking selfies with excellent dynamic range and just the right amount of sharpness
  • Portrait photos are quite good on the selfie camera as well - the subject separation is quite well
  • Video recording looks great with detail and dynamic range - stabilisation is also excellent with the Super Steady mode
  • Excellent stereo speakers with Dolby Atmos, providing richer, deeper sound
  • Very good battery life with the 4510 mAh battery - which is the biggest OnePlus has ever put in a handset, and larger than the power pack you'll find in the Samsung Galaxy S20 Plus, Huawei P40 Pro and iPhone 11 Pro - it will comfortably last a full day on a single charge
  • Excellent fast charging - OnePlus has upgraded its Warp Charge 30T charging, to get you from 0% to 50% in 23 minutes via a wired connection
  • OnePlus has included fast wireless charging called Warp Charge 30 Wireless, and it takes you from 1% to 50% in 30 minutes (though, the faster charging can only be achieved with OnePlus wireless charger which costs extra)
  • With the OnePlus 8 Pro, you get an unabashed flagship, with all the bells and whistles - powerful specs, an amazing display, fast wireless charging, and water resistance make the OnePlus 8 Pro a great alternative to the Galaxy S20 Plus, and it saves you thousands of rupees
  • 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 OnePlus 8 Pro is a large handset, and many users will find that two hands are required to hold it securely
  • There doesn't seem to be any 'palm rejection', which could be an issue while dealing with the extreme curved display and you might see frequent accidental touches
  • Overall, the OnePlus 8 Pro has a great set of cameras, but they're still not on the same level as the best of the best like the iPhone's and the Pixel's
  • However, if you want the very best smartphone photography experience, the iPhone 11 series and the S20 series are still the way to go
  • 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
