2-minute Review [Positives]
  • Flashy, colourful glass rear with a gradient tone along with Gorilla Glass 5 at the front and back make it feel as premium as it gets
  • The centrepiece of the rear design is the circular patch around the camera strip, with smooth finish while the glass around it looks frosted - giving the POCO X2 a differentiating look
  • The front looks slick, with all-screen, minimum bezels and punch holes for the front cameras
  • Lightning-fast fingerprint sensor (though, it's side mounted & can take some time getting used to)
  • Gorgeous, super smooth 120Hz Full HD+ IPS display - the added smoothness to transitions throughout the phone is love at first sight, every scroll and swipe will feel buttery smooth, and once you experience this, it is hard to go back to 60Hz
  • Strong brightness and great sunlight legibility
  • The POCO X2 has Widevine L1 from day one, allowing you to stream 1080p videos from Netflix and other streaming services
  • Poco's UI is identified as Poco Launcher as well as MIUI in different parts of the UI - MIUI has always been one of the most refined Android UIs out there, and continues to get even better - it offers a good combination of aesthetics, useful added functionality, lots of customisability, and optimisation - not only is there now an app drawer, but it has tabs that filter various categories of apps for easy access
  • Excellent performance, backed by the scorching Snapdragon 730G - the Poco X2 breezes through apps and games - heavy games run smooth, with PUBG Mobile running at high graphics as default
  • Good heat management - the phone doesn't get too hot in use, and only feels mildly warm when playing games or using the cameras for a while
  • Excellent quad cameras for the price - the primary 64MP + 8MP ultra-wide camera + 2MP macro camera + 2MP depth sensor
  • The 64MP main camera saves 16MP photos, and the daylight pictures came out excellent for the class - the resolved detail is plenty, the contrast is great, and the dynamic range is rather high with vibrant colours - you can shoot in the full 64MP resolution and the photos look quite good, with a downright impressive level of detail
  • The 8MP ultra-wide cam snaps good photos with enough level of detail and commendable contrast - very good ultra-wide shots for the class (though the quality is not as good as the main snapper, as expected)
  • The POCO X2's 2MP macro cam has autofocus, unlike the majority of the macro shooters out there, be it flagship or not - it is much easier to use, and the closeups are also good
  • The portrait photos are very detailed, have convincing blur and with some fine-tuning they can easily rival some of the best portraits from recent smartphones in this price range
  • Low-light shots are also good from both primary & ultra-wide cam - the night mode makes a considerable difference and you don't have to stand still too long - the night mode brightens frames and shows details that would have been otherwise lost in the shadows
  • Very good dual 20MP + 2MP selfie camera - there is enough detail in selfies, the colours are nice, and the contrast is good
  • Selfie portraits are good too - edge detection is quite accurate
  • Video recording is also good with good stabilisation, crisp details and smooth motion tracking
  • Overall, one of the best cameras you'll find in any phone around the price of the POCO X2
  • Good single speaker at the bottom - it's very loud and the sound is impressively deep and rich
  • Call quality on the Poco X2 is very good and there is barely any noticeable distortion or jarring while taking calls
  • Solid battery life with the 4500 mAh cell - can easily accommodate a day and half worth of moderate use
  • Impressive and unmatched 27W Fast charging for the price - the cherry on top is the included 27W Fast Charger which fills the phone in an hour
  • Offering high-end specifications at rock-bottom prices is the mantra POCO follows and the POCO X2 is so well priced it makes very good value for money phones like the Realme X2 and the Redmi K20 seem a little worse in comparison - the POCO X2 is the new value champ in its price segment - the processor, RAM, storage, battery, and cameras are all strong, and there's nothing to complain about in terms of build quality or the included accessories (though some people might struggle with the sheer size of this device and the ads in MIUI)
  • 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 POCO X2 is a humongous phone with its 6.67-inch display, making one-handed use potentially awkward - a bit heavy too at 208g
  • There is a noticeable shadow around the dual punch-hole cameras when displaying brighter content and it could be annoying - it could also be distracting when watching full-screen content
  • There's a lot of preloaded bloatware which sends you multiple annoying notifications each day asking you to download more through the company's own GetApps store - you'll see ads and promoted content in many of the default apps (though, it seems to have been toned down a little compared to before)
  • The camera app is a bit complicated for an average user, there is no clear way to navigate through all cameras - you have zoom controls for switching between ultra-wide and primary and different toggles for portrait and macro mode
  • 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
