2-minute Review [Positives]	Elegant and attractive looks - the Nord has the same design language as OnePlus flagships, and the in-hand feel is excellent Front design is similar to some of the Oppo and Realme phones with its dual punch-hole selfie camera The flat panel makes it significantly easier to use the phone with single hand The in-display fingerprint sensor as well as the face unlock works very well, and all it needs is a quick tap to unlock the phone Bright, crisp 6.44-inch Super AMOLED display - the 90Hz display on the Nord is just as vibrant and fluid as the OnePlus 8 with punchy colours and excellent viewing angles The brightness levels are more than enough for any situation indoors while being enough for direct under-the-sun use The OxygenOS is delight to have at this price, it is one of the most thoughtful, simple and clean Android skins which arguably offers the best user experience at this price point Snappy and fluid performance from the new Snapdragon 765G - in regular use there's hardly any difference between the Nord and OnePlus 8, it feels as fast and responsive as it's more expensive sibling - heavy games like PUBG mobile and Asphalt 9 run at their highest setting without any issue or lag Good camera setup for the price - a 48MP primary camera, 8MP ultra-wide camera, 5MP depth sensor and a 2MP macro The primary camera is the same as the one on the OnePlus 8 and captures good detail and colours are really punchy and vibrant The ultra-wide camera captures does a good job with colours and HDR with expected weaker details than the primary camera The macro camera works decently well when there is a good amount of ambient light around the subject The portrait lens also does a decent job, creates good bokeh and brings out nice portrait shots Low-light photos turn out decent, given strong enough light sources around - for darker scenes, OnePlus offers a dedicated Night mode which can be quite effective in brightening up photos Very good dual selfie cameras, a 32MP primary and an 8MP ultra-wide - the primary camera captures very good details, skin tones look good, and HDR is handled well The ultra-wide front camera is a thoughtful addition which captures a lot wider scene for all your groupies Overall, OnePlus has accumulated a great set of cameras for the price, they need some more tuning which OnePlus is known to provide with future updates Very good battery life from the 4115 mAh battery - it can easily accommodate for a day and half worth of usage with light to moderate use at 90 Hz, switching to 60 Hz improves the battery even futher Very good fast charging with the provided 30W charger in the box - it is able to take the battery to around 93 per cent in an hour, which is fairly quick The OnePlus Nord ticks all the right boxes - you get a 90Hz AMOLED display, robust hardware, good set of cameras at the back and front, unmatched software experience, and 30W fast charging - OnePlus did a fantastic job distilling the essence of its flagships into the Nord, and the result is one of the best mid-range phones in 2020	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 Nord has a plastic mid-frame which definitely affects its premium positioning	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
