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)
  • Eye-catching, attractive design, like a lot of recent Vivo and Oppo phones - the back of the phone is all sorts of interesting, with gradient style colorways - it’s definitely going to turn heads
  • On the front, the phone is all screen - and looks really damn good - it's an expansive viewing field that is as close to the concept of all-screen devices as we’ve gotten to so far
  • This is not a small phone, but the gently curved edges and back make it very comfortable to hold - Vivo has also done a really good job with weight distribution, and the phone nestles very easily in the palm of your hand
  • There’s a direct shortcut for Google Assistant on the left side of the phone - double clicking the button activates Google Lens or Vivo’s own Jovi image recognition
  • The in-display fingerprint scanner works perfectly well
  • There's also perfectly capable face recognition that uses the unique pop-up selfie camera (takes less than half a second to pop-out)
  • The large, vibrant, 6.23 inch display Super AMOLED display of course stands out - the screen is nice and sharp with crisp text rendering - it's also excellent for media consumption, with no notch to disrupt a clean experience - it also gets sufficiently bright for outdoor use in direct sunlight
  • On it's own, FunTouch OS UI is pretty functional, customizable, and smooth
  • The Snapdragon 675 is a pretty good performer, just a notch below the 710 is real life use cases - navigating through the interface and jumping between apps is very smooth, and playing games like PUBG is also a very enjoyable experience (even with graphics set to high)
  • Pretty decent set of rear cameras - especially in day light - the Vivo V15 Pro has three different rear camera modules - there’s a 5MP depth-sensing camera, an 8MP wide-angle sensor and of course a 48MP primary camera - while you can shoot full resolution, 48MP, shots from the camera, it works best when pixel-binned to 12MP
  • Particularly useful is the ultra wide lens - which gives a really nice way to get a very different perspective
  • Very good popup selfie camera - that pops out in under half a second - and produces some good quality images in most lighting conditions - there's also a very powerful beauty mode, if you are into that sort of stuff - overall, as far as selfie cameras go, this is one of the best, not just in this price range, but on any smartphone
  • Good battery life with a 3700mAh battery -with moderate use the phone can give you up to 1.5 days
  • Supports fast charging with Vivo’s “Dual Engine” charging - you get a 25 percent charge in 15 minutes - and a full charge in about 1 and a half hours
  • Overall, the V15 Pro is another great, innovative device from the Vivo camp - you can go for it if you want a good balance between performance and design, and an amazing, true 'full screen' display - if on the other hand you are looking for the best rear camera experience or the best performance - look instead at the Poco F1, OnePlus 6T and Honor View 20
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
  • The volume rocker is a little bit too high up, sometimes requiring a little shimmy to reach
  • The location of the fingerprint touchpoint for the in-display scanner is a little too low on the screen and you might find yourself having to bend your thumb over a bit too much to unlock the phone
  • Coming as the the Vivo V15 Pro does with a glass back, the usual caveats apply - the phone is slippery, and is nearly impossible to keep the back clean of fingerprints and smudges (having said that, Vivo is throwing a well-designed case in the box, which takes care of these issues)
  • The lack of Widewine L1 certification means that the phone can’t stream HD videos on Netflix or Amazon (they will stream at 540p resolution)
  • It is still pretty much a clone of iOS though - and that might not be everyone's cup of tea
  • It also packs a bunch of bloatware (mostly un-installable, thankfully)
  • It's also somewhat buggy at places - for instance the aggressive battery management means that it sometimes force closes apps unexpectedly
  • It does get slightly warm though, when put under heavy continuous load
  • Sound quality during video recording is pretty average
  • Overall, the rear cameras are good, but they are still a notch below the top competitors - the Pocophone, Honor View 20 and OnePlus 6T (on the other hand, the front camera of the V15 Pro is arguably better than that of these three)
  • Uses the old microUSB standard, instead of the modern USB-C
