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 of the Realme X3 SuperZoom is identical to the Realme 6 Pro - it looks elegant and beautiful (though, the plastic frame and overused design might not be of everyone's taste) The dual hole-punch cutout at the front gives the phone a modern appearance Fingerprint Sensor is embedded in the unlock button and it is quick (though, it is a bit unreliable) Good 6.6-inch IPS LCD FHD+ display - it gives off quite punchy, and vivid colours (though, an AMOLED display would be appreciated at this price) The 120Hz refresh rate on the Realme X3 SuperZoom makes for a smooth and seamless visual experience Brightness levels are more than sufficient for outdoor use Software is one place where Realme has taken a big leap, the Realme UI is easy to use - it is also packed with features such as app cloning, Google Assistant, a gaming mode, digital wellbeing, and contactless payments among others - there are some more interesting and useful features like Realme Dual-Mode Audio, which allows you to connect a Bluetooth and a wired headset at the same time to listen to music on the smartphone Excellent performance for the price - the Snapdragon 855 Plus is a powerful chip, so as expected, general usage and multitasking is handled superbly - gaming performance is nothing to scoff at, the phone handles heavy games like PUBG at the highest settings with ease Good quad cameras for the price - there's a 64MP primary sensor, an 8MP ultra-wide camera, an 8MP periscope telephoto camera, and a 2MP macro camera Daylight photos from the SuperZoom's main cam are very good - it captures a lot of fine detail and processes it in a natural manner, so it doesn't have an artificial look The 8MP ultra-wide angle cam turns in a solid performance too, with good detail and wide dynamic range The telephoto camera of the Realme is the real standout feature - it can zoom up to 5x optically and captures sharp and detailed images with high contrast - colours and dynamic range are praiseworthy as well Portraits are good too, the blur quality is nice and the intensity is just right Very good dual selfie cameras, 32MP primary and 8MP Ultra-wide - 32MP camera of the Realme X3 SuperZoom takes really good selfies with a ton of detail and the wide-angle camera is great for taking a group selfie Very good battery life with the 4200 mAh cell - the SuperZoom delivers a solid day and a half of battery life, even with heavy usage The bundled 30W fast charger is very quick and manages to charge the battery from zero to about 90 per cent in an hour The X3 Superzoom is a pretty good buy for its price - the display is great for an LCD, performance is solid, and battery life is excellent and the cameras are good enough
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 Realme X3 SuperZoom is quite chunky at 8.9mm and a bit heavy at 202g Low-light photos from the Realme X3 SuperZoom aren't quite as good, images from the main cam are on the soft side and quite noisy too - Night mode improves things a bit but the quality of the shots is still not exciting The macro lens doesn't really excel at what it is supposed to do, the detailing of the images is low because of the very low 2MP resolution (though, it help take closer shots of smaller subjects) Overall, the Realme X3 SuperZoom offer versatile cameras, but they are inconsistent and a bit unreliable to be the go-to shooter in your pocket No headphone jack
