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)
  • The design feels fresh and vibrant - phone's sleek profile is eye-catching, with a matte back glass, it is one of the nicest looking phones for the price
  • The phone looks quite flawless from the back, it features a rather flashy back cover
  • The Vivo V20 is one of the lightest around in the price segment, and at 7.38mm in thickness, it is surprisingly slim
  • The power button has a texture to give it a more distinguished feeling
  • The in-display fingerprint scanner, as well as face recognition, are quick to unlock the V20
  • The display is a gorgeous 6.44-inch AMOLED FHD+ panel which promises vibrant and life-like colours - the contrast is impressive and it also supports HDR10 for high-quality video playback
  • It gets bright enough for using the device even under harsh sunlight
  • The Vivo V20 comes with Android 11 out of the box, with Vivo's new Funtouch OS 11 - this new skin by Vivo brings several bells and whistles, and a much cleaner, simpler interface - there's an improved dark mode and tons of customisation options
  • Good performance from the Snapdragon 720G SoC - it is good enough to help you through tasks of daily use and even running multiple apps simultaneously - casual gaming is no issue and heavy games run at medium settings, which is decent
  • Good triple cameras for the price - a 64MP primary camera, an 8MP ultra-wide-angle camera, and a 2MP mono camera
  • Photos shot in bright sunny conditions turned out well - images clicked using the device generally come out with life-like colours and packing good detail
  • The Ultra-wide camera adds fun new perspectives, it can take dramatic super-wide-angle photos with lesser details than the main camera - besides, it can also take Macro shots, which come out with good detail, and you end up with a higher resolution image compared to what most dedicated macro cameras produce
  • Portraits have good edge detection and you do get the option to set the intensity of the blur effect - beautification is enabled by default which smoothens skin textures
  • Low-light camera performance is good, photos have little noise and details in brighter areas are decent - enabling Night mode improves the level of detail
  • The 44MP selfie camera is very good at what it does - daylight selfies are sharp with accurate colours and good details, there's also an Eye Autofocus option that keeps the subject in sharp focus - portrait selfies are possible and you can set the level of blur before taking a shot
  • Video recording in daylight is good, video recording tops out at 4K for the primary as well as the selfie shooter - footage shot in 4K, as well as 1080p, is stabilised (though, video shot in low light has a shimmer effect at both resolutions, which isn't good)
  • Overall, cameras are one of the highlights of the phone and they can take on any other capable camera phone at this price
  • Good battery life from the 4000 mAh battery - it can easily manage to keep the phone going on for around a day on moderate-heavy use
  • Charging is quick with the supplied 33W FlashCharge charger - it takes the V20 to 98 percent in an hour
  • If you value looks over other aspects, the Vivo V20 will appeal to you, it is well designed and feels premium to the touch - the device also offers above par photography performance, it emerges as a very good option for taking pictures and shooting videos
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
  • Because of its slim profile, the Vivo V20 is a bit slippery
  • Though, it isn't a high-refresh-rate panel
  • However, this isn't the best performing phone at the price, there are better options available like the OnePlus Nord
  • However, if heavy-duty gaming is what you're looking for, alternatives such as the OnePlus Nord offer significantly better performance, you can also consider the Galaxy M51 for its insane battery life powered by a 7000 mAh battery
