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)	Stunning looks, similar rainbow-like effects at the back as the Galaxy A50s when caught against the light, and a prism-like pattern that Samsung calls a “3D prism design” - it's a head-turner no doubt While it supports a polycarbonate back, it still manages to look premium The front looks stylish and modern too with a single punch-hole in the upper middle of the display Compact and light for the display size and battery capacity, at just 172g, and 7.9mm in thickness Bright, large 6.5-inches Super AMOLED panel with a full-HD+ resolution - its punchy colours make it a joy to stream content, while games also look great on the panel because of its high colour accuracy There's Widevine L1 support by default, which makes streaming content in HD possible Comes with Android 10 out of the box - Samsung's One UI 2 is now one of the better, more clean and streamlined Android UIs around, and is well optimised for modern large displays (like this one) Samsung has also added some neat features including a Game Booster and an intuitive gesture-based navigation system Decent performance with the same Exynos 9611 processor as the Galaxy A50s (similar to Qualcomm Snapdragon 660/665) - the experience is fairly smooth throughout with games like PUBG Mobile and Asphalt 9 Decent quad camera setup at the back - a 48MP primary sensor + 12MP wide-angle camera + 5MP macro camera + 5MP depth sensor Under good light, the Galaxy A51's primary camera managed to capture detailed shots with good dynamic range - images are reasonably sharp, noise is also competently removed, colours are generally nice, and the phone strikes a good balance with saturation The ultra wide-angle cam is a significant upgrade from the one on the A50s, and it offers improved sharpness and detail - dynamic range is also substantially better, making for an altogether pretty capable ultra-wide camera as far as mid-rangers go Macro camera turns out quite good close ups - you can get a lot closer to your subject when using the macro camera and the sensor picks up a fair bit of detail Very good portrait mode ("Live focus") - image quality is good and the depth camera helps the Galaxy A51 do a decent job of edge detection The front 32MP camera is decent and produces nice colours, the detail is quite good as far as selfie cameras go - portrait selfie mode is decent too Decent video recording from both primary and wide cameras with dedicated 'super steady' mode which allows you to shoot decent “action” videos (though stabilisation is not available at 4K) Decent bottom-firing speaker - sufficient for personal listening Solid, dependent battery life from the 4000 mah battery - will easily manage to get a day and a half's worth of regular use Reasonable 15W fast charging - charges 67 percent in an hour (though, not as quick as others in this segment such as the Redmi K20 Pro) Overall, a decent and likeable smartphone from Samsung - offers a polished experience, a slim and light body, solid battery life, a crisp display, and of course the Samsung brand (though, the performance at this price is a letdown)
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 in-display fingerprint sensor as well as the facial recognition are on the slower side The glossy body is prone to picking up fingerprints There's still some bloatware pre-installed, including third-party apps and some of Samsung's own apps such as Samsung Shop (though most of them can be uninstalled) At this price, the performance feels weak - there are cheaper phones that offer much better performance, like the Redmi K20 & the Realme X2 Low light photos out of the Galaxy A51 aren't great (from all cameras) - The output is soft and noisy, while the colours are relatively desaturated Overall, while the Galaxy A51 offers good cameras, there are certainly better options available, such as the Redmi K20 Pro However, as far the value for money goes, the Galaxy A51 is far behind from the competition - there are better options like the Redmi K20 Pro which gets you a flagship-grade processor, an HDR display, more premium materials, and even better cameras - in fact, for a bit less money, you could also get the Redmi K20, which is also very capable
