2-minute Review [Positives]
  • 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
  • Premium build & gorgeous design: Dual Gorilla Glass 5 build, with an attractive, striking gradient design
  • Modern front panel, with a small notch
  • Compact form-factor - fairly easy to use one-handed
  • Decent, reasonably accurate under-display fingerprint scanner (it's not the fastest though)
  • Large, high-contrast AMOLED display
  • Being part of the Android One series, you get a simple/stock Android experience, along with a promise of minimum 2 years of Android updates
  • With the powerful Snapdragon 665 at the core, you get smooth dependable performance all-round - it's great for gaming too
  • Very good triple camera setup on the rear (48MP primary + 8MP ultra-wide + 2MP depth)
  • Images turn out with high level of detail and true-to-life colors - the contrast is also excellent, while the dynamic range is notably wide
  • 8MP images with the ultrawide-angle camera are decent too - its per-pixel quality is much lower than the main camera, but the colors are still nice, and noise is minimal
  • Portrait mode works well - shots are detailed, with excellent subject separation and convincing faux blur
  • Night mode works decently well too
  • Excellent selfies too, from the 32MP selfie camera - there is enough detail, the colors are nice, and the images are sharp enough
  • Good video recording performance too - both 4K and 1080p videos are sharp and detailed, contrast is excellent, color rendition is quite nice and true to life, and the dynamic range is decent - at 1080p 30fps, there is also EIS, which works well
  • Overall, the Mi A3 is easily one of the better camera phones in this price bracket, going head-to-head with excellent camera phones like the Redmi Note 7 Pro
  • Very good speaker - loud, with fairly rich and deep sound
  • Very good battery life with a large 4030mAH battery - you will comfortably get 1.5 days of use
  • Fast charging (Quick Charge 3.0) support, with up to 18W charger
  • Overall, the Mi A3 is an all-round good Android One phone, that does well on most counts, and additionally packs a stock Android experience (plus promised updates) - for a lot of users, who value a stock Android experience, and whose main consumption on the phone is images & video, it will be a good bet
2-minute Review [Negatives]
  • 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
  • The 720p resolution is on the low side though for a PenTile AMOLED display of that size, and this is the only weak-ish point of the Mi A3 - the screen is not the most ideally suited for long reading or browsing
  • The phones ships with a lower 10W charger though, that gives still decent, but not the quickest charging speeds - it recharges from 0 to 28% in 30 mins, while a full charge takes about 150 mins
  • But if you tend to do a lot of long reading on your phone, then you might want to consider higher resolution phones in this price bracket (and there are many good ones out there)
