2-minute Review [Positives]
  • Premium front and back glass design, with a metal frame sitting in between (similar to Galaxy S8 and Galaxy Note 8)
  • IP68 certification for water and dust resistance
  • Beautiful 6 inch edge-to-edge display with 18.5:9 aspect ratio - you’ll love playing games, watching videos or web browsing on the screen - the display is gorgeous, and the color reproduction is pretty good - sunlight legibility is good too
  • Samsung's UI over Android is pretty lean and includes useful stuff like Secure Folder, and Samsung Pay (which comes with UPI, Paytm and Mobikwik integration)
  • The Bixby AI functionality adds useful stuff like Bixby Vision in the camera app, which lets you point the camera at an object or place to offer relevant results - you can also use Bixby Vision to scan QR Codes and point at text to translate in any given language supported by the assistant
  • Good speed/performance in daily use, as well as in high-end games
  • Decent (though not exceptional) front facing dual camera setup - has a good bokeh effect, especially in daylight
  • Good battery life - lasts the whole day even with heavy use
  • Decent 'fast-charging' support - charging from empty to full takes about an hour and 45 minutes
  • 'True' dual SIM experience
  • Refined, understated design - the phone is sleek and features an all-black aluminum frame and a glass back with tapered edges, which make it very comfortable to hold
  • Surprisingly easy to handle, especially considering the 6.28-inch screen - the tall 19:9 aspect ratio helps a lot, and it also gives the front of the phone that modern bezel-less look everyone craves these days
  • Fans of minimalism will enjoy the Vivo X21 too - with the fingerprint sensor hidden under the screen, the back of the phone is very clean
  • The key USP of the phone, however, is the world's first under-display fingerprint sensor - the sensor works well most of the time, although it can be buggy now and then
  • In case you are not into that, you can also opt for the infrared-based facial recognition, which is fast and accurate, and pleasantly works in all kinds of lighting conditions
  • The Vivo X21’s display is otherwise beautiful too with the characteristic vibrant color palette and inky blacks of an OLED display - it has excellent brightness levels, and outdoor visibility too
  • The Vivo X21 also features an always-on display that looks pretty similar to Samsung’s implementation, with a clock and other notifications on screen
  • Good speed/performance backed by the solid Snapdragon 660 processor and an ample 6GB of RAM - mostly, in actual use, you will be hard pressed to see any differences in performance even compared to the top-end Android flagships like the Pixel 2 or the Galaxy S9
  • Decent dual camera setup at the back - does well especially in good lighting conditions, and with bokeh effects - it's not quite to the level of the Pixel 2 or the Galaxy S9 - but for its price bracket, it does a decent job
  • The front 12MP camera is decent too, and can also do (software based) bokeh images
  • Good audio quality via headphones
  • The single bottom-firing speaker also gets pretty loud
  • Good battery life - will last the day with medium to heavy use
  • Fast charging support
2-minute Review [Negatives]
  • A little bit on the thick and heavy side, compared to its main competitors - the OnePlus 5T, and the Honor View 10
  • As in case with all the smartphones with glass panels, it is slippery and a bit of a fingerprint magnet (luckily Samsung has bundled a clear case along with the smartphone)
  • Face unlock is iffy and not too accurate (you are better off using the fingerprint sensor)
  • Samsung's Experience UI, while decent, could do with less of bloat
  • Rear camera is decent but falls behind it's main competitors - the OnePlus 5T, and the Honor View 10 - handling of details and exposures is ordinary, video recording is average, and low light performance is not great either
  • On the whole, seen in absolute terms, the Galaxy A8+ is a pretty decent all-round phone, but compared to the likes of OnePlus 5T and the Honor View 10 (the prevailing leaders in this price segment), it falls behind - the OnePlus 5T has a distinct edge in terms of software & performance - and the View 10 in terms of camera
  • No water resistance - a feature thats now present in most phones in this price bracket
  • One area where the X21 loses out is the refinement of the UI - the OS which is basically a copy of the iOS, can often be un-intuitive, and sometimes buggy - the devil is in the details - and details are not very well done here
  • Uses the old microUSB standard, instead of the modern USB-C port
  • On the whole, the Vivo X21 is a good all-round phone, and has an innovative under-glass fingerprint sensor, but it's let down to some extent by its UI - everything considered, unless you are into the cutting edge fingerprint sensor tech, you are likely to find better overall value devices in this price segment, like the OnePlus 6, or the Honor 10
