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)
  • Slick, trendy design - with a punch-hole front camera, which is one of the smaller ones on a phone to date
  • The good bit is despite sporting the four cameras, the back panel of the V17 doesn’t look cluttered - the rectangular (vertically) quad-camera module on the top left corner of the back adds to the overall design
  • Amazingly lightweight, for a phone with 4500 mAh battery inside
  • Despite having the same screen size as the V17 Pro model, it very easy to use with just one hand - which was difficult with the V17 Pro
  • Both the in-display fingerprint sensor & Face Unlock are fast and unlock the smartphone quickly
  • Beautiful 6.44-inch, Super AMOLED display with a punch-hole, which gives it an amazing screen-to-body of 91.38 per cent - it’s a delight watching videos on the Vivo V17
  • The full-screen display also get pretty bright in all lighting conditions, exhibits very good viewing angles and punchy colours
  • The Vivo V17 also comes with an always-on display option, which is useful
  • Solid performance with the Snapdragon 675 at the core - every-day use to gaming - it’s all lag-free
  • Good quad-rear camera setup (48MP main camera + 8MP ultra-wide camera + 2MP macro camera + 2MP depth sensor)
  • Pictures shot in bright daylight show a good amount of details and decent colours - Vivo V17 doesn’t pop the colours too much and captures the right colour-shade
  • The ultra-wide-angle lens offers a new perspective - shots look decent (though they are less detailed)
  • The portrait shots also turn out to be good, but the edge detection could have been better
  • Super Macro camera mode shows great details and good colours - the macro mode works best in good lighting conditions
  • The low-light pictures with the V17 turn out well - the Night camera mode of the V17 especially captures better details and colours in low-light conditions compared to the default photo mode
  • The 32MP front camera on the Vivo V17 clicks great selfies in good light
  • The night mode also works for the front camera and again it works pretty well
  • Very good battery life with a large 4500mAh battery - you will easily get about 1.5 days of moderate use
  • 18W fast charging support: it takes around 1.5 hours (approx) to charge the V17 fully with its bundled charger
  • Overall, the V17 is reasonably good value - especially if camera and design are your primary priorities, the Vivo V17 is a solid choice to consider in the under 30k segment - it does well on both those parameters
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 Software continues to be a relatively weak point for Vivo, with a cluttered Funtouch UI (though it is quite feature-packed)
  • This is certainly not the best performing phone of this price bracket though - you get a much more powerful Snapdragon 730 with the Redmi K20 - in fact, there are the Vivo Z1 Pro and the Vivo Z1X that again cost less and come with a newer Snapdragon 712
  • Low light video though, is below average
  • If you are looking for an all-rounder though, you will have better options around especially in terms of software & performance - you will want to look at the likes of Realme XT, and Redmi K20
