2-minute Review [Positives]
  • Looks nice upfront with a dewdrop notch display with almost no bezels on the sides (however, it does have a slight chin at the bottom)
  • Light, compact and easy to hold
  • Decent 6.3-inch FHD+ display - the LCD panel comes with HDR10 support, which is pretty good considering the price range - it also produces nice, punchy colors, and works fine in outdoor light conditions
  • Lenovo's ZUI is pretty close to stock Android - which is a good thing - it keeps things nice and simple
  • Good performance from a strong Qualcomm Snapdragon 710 SoC - the phone performs comfortably, and handles moderate multitasking well - gaming performance is good too
  • Triple-camera setup at the back includes a 16-megapixel primary camera sensor, an 8-megapixel telephoto lens with 2x optical zoom (a rarity in this segment), and a 5-megapixel depth sensor
  • Performance of the 16-megapixel primary camera is good, especially in daylight - background colors come out quite richly in the pictures
  • Good focus speed
  • Good portrait mode photos (with good edge detection)
  • Overall, the K10 Note has capable cameras for the price bracket, though it's no quite there at the top of the pile
  • The smartphone comes with a single speaker, but with Dolby Atmos support, which improves the overall audio performance
  • Good battery life with a large 4050mAh battery - you will get around 1.5 days of moderate use
  • Stylish, slick, premium looks (looks more expensive than it is), good build quality
  • The rear camera module has a copper accent on the edges, which further adds to the premium-ness
  • The front is modern with a 6.53-inch FHD+ IPS display with a dewdrop notch, and minimal bezels
  • Both the fingerprint scanner, and face unlock are quick
  • The IPS display is crisp, and boasts good legibility and viewing angles
  • Very good performance for the price category with a powerful Snapdragon 675 at the core - it delivers smooth performance not just in daily use, but high-end games like PUBG
  • Decent triple-camera setup at the back: 16-megapixel primary lens + 8-super-wide-angle lens + 2-megapixel super macro lens - in good lighting conditions, the images shot offer good exposure as well as good color production
  • Fast focus speed
  • Good portrait mode - blurs the background quite well and gives you good bokeh effect
  • Good 16-megapixel front facing camera - works well in both day-light and low-light conditions, and has a good portrait mode too
  • Overall, the camera setup on the U20 is pretty decent for the price bracket (but not the best)
  • Excellent battery life with a large 5000mAh battery - you should get a comfortable 2 days of use
  • Fast charging support (18W) - you can recharge your phone's battery in about two-and-half hours
  • If you value performance, battery and design in your phone, the the U20 is another excellent option from Vivo, after its popular predecessor, the U10 - the only area where it lags a little behind the competition from Xiaomi and Realme is the cameras
2-minute Review [Negatives]
  • The back design is a little bland however, and the shiny plastic body attracts smudges very easily
  • But given the fact that the only changes are to the look of the notification shade, and the task switcher, and no major features are added, the ZUI layer could have been easily skipped, which would have resulted in an even more responsive feeling UI
  • While the telephoto lens sounds impressive on paper, the quality is average - you will find that you can get comparable results with digital zoom on competing smartphones
  • The cameras are also average in low light - there is a dedicated night mode, and it does help a bit, but not much
  • Video recording quality is average - audio is also a bit of an issue too, as it generally sounds tinny
  • Average selfie camera - skin textures look a bit sharpened and colours aren't always accurate - there is no flash either for night photos
  • While it does technically 18W fast charging, the actual charging speed is not too great - the battery charges about 63 percent in an hour and takes almost two and half hours to fully charge
  • While the K10 Note does have some aces up its sleeves - Snapdragon 710 SoC, 4050mAh battery and a reasonably capable triple camera setup - it also enters a market segment where the competition from the likes of Xiaomi, Realme, Samsung, Oppo, and Vivo is ruthless - it's worth considering if you want an HDR10 supported device for entertainment purposes or a lightweight device with near stock android experience - but otherwise, the competition is certainly better
  • Somewhat bulky
  • Vivo's Funtouch UI is one of the heavier Android skins around, and packs plenty of bloatware - which means that if you like your phones simple and fuss-free, it's not the best option around
  • The super-wide angle camera, and the macro camera, while offering some interesting framing options, are not that good in terms of image quality
  • Low light camera performance from the rear camera setup is average (the Night mode does help a bit though)
  • Uses the old microUSB port, instead of the modern USB-C standard
