2-minute Review [Positives]
  • 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)
  • Premium, stylish glass-sandwich design - two glass sheets joined by an anodized aluminum frame
  • The back has a nice gradient effect - there's a subtle "X" pattern if you shine a light at it
  • Cold glass, colder metal, all curved and melded into one another, the Realme X2 Pro feels great in hand
  • Excellent, fast in-display fingerprint scanner and face unlock
  • Beautiful, large, bright, vibrant OLED display, with a cool 90Hz refresh rate - the best display panel you will get at this price point
  • The 90Hz refresh rate means everything feels super snappy on the phone - from UI animations, webpage scrolling, to games
  • The screen also delivers HDR10+ support and a bunch of colour modes too, as well as a dark mode to take advantage of the OLED’s inky blacks
  • ColorOS is now more streamlined (and less bloat-y) than before, and still packs a bunch of useful add-on features, like Game space
  • Top-end flagship performance with the Snapdragon 855+ beast at the core (the cheapest phone with the flagship 855+ at present) - the X2 Pro steamrolls through anything you throw at it, including high-end games
  • Gaming on the phone is especially a treat, also because of the 90Hz screen
  • Nice, versatile quad camera setup: 64MP primary + 13MP telephoto + 8MP ultra-wide + 2MP depth sensor
  • In daylight, the 64MP camera can grab some great shots - detail is great and dynamic range is fair
  • Very good portrait mode
  • The ultra-wide, and macro modes provide for some interesting framing options (though quality wise, they are not quite up there with the primary camera)
  • The telephoto lens is capable of 2X optical zoom, 5X hybrid zoom, and a total of 20X digital zoom - and, up to 5x zoom, the quality is pretty good, especially in good lighting conditions
  • Very good video capture with impressive electronic image stabilisation from the main camera - comparable to much more expensive phones
  • Good selfie camera too - its 16MP resolution captures detailed shots, and it shoots at up to FullHD video
  • Overall, the camera setup on the X2 Pro is very good for the price bracket, but it's not the best (Redmi K20 Pro, and Oneplus 7T do slightly better)
  • Excellent Dolby tuned stereo speakers - they are both loud and hard to cover up - listening to music on the phone is a joy
  • Very good battery life with a large 4000mAh battery - will give you up to 1.5 days of use with moderate usage
  • Includes crazy-fast 50W fast charging - the fastest in the industry till date - even beating top-end flagships like the Mate 30 Pro and Samsung Galaxy Note 10 (by a massive margin) - it goes flat to 100% in just 30 minutes!
  • The X2 Pro is a smashing entry by Realme in the flagship space - it's crazy good value for money, completely changes the affordable flagship landscape, and is a power user's dream - as long as you are ok with a not-the-best-at-this-price-range camera, it will be hard to do better than the X2 Pro
2-minute Review [Negatives]
  • 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
  • A bit beefy at 199g and 8.7mm thick
  • Like all glass backs, this one too is slippery and attracts fingerprints and smudges
  • It's still not as clean/simple as stock Android of course - very few custom skins are
  • Low light performance and the night mode aren't that great, with the lack of OIS
  • If you do want the best-camera-for-the-buck, or a notch-less screen however, consider the Xiaomi's Redmi K20 Pro - and if you are really keen on a clean, stock like Android experience, consider the OnePlus 7T (at a slightly higher price point)
