2-minute Review [Positives]
  • Stunning, beautiful design, that's a treat to the eyes - Vivo S1 is easily among the most well-designed smartphones to launch this year
  • There is a mesmerising dual tone finish on the metal frame, and a unique 'diamond lattice' design back, that reflects colors in the most interesting ways - this is the kind of smartphone that will definitely get you a lot of Wows from everyone around
  • It not only looks great but also feels great to hold and use thanks to the 2.5D design
  • Fast in-display fingerprint sensor
  • Dedicated Google Assistant button
  • Very good 6.38-inch AMOLED display - you will get deep blacks and punchy colors
  • Funtouch OS UI looks very similar to iOS, and is pretty feature packed, including a good gesture navigation system, and an 'Ultra Game' mode
  • Daily performance is smooth all-round with a Helio P65 processor (similar to the Helio P70, and Snapdragon 660), and most games run well too
  • Decent set of triple rear cameras - 16MP primary + 8MP ultra-wide + 2MP depth
  • The primary camera captures images with fairly good details
  • The depth camera helps with some decent portraits
  • The 32MP selfie camera is decent too, and does especially well with details (though the image softening algorithm is a bit too aggressive)
  • Outstanding battery life with a large 4500mAh battery paired with a low-power MediaTek Helio P65 SoC - you will comfortably clock 2 days of use
  • Bundled 18W fast charger
  • Jazzy, eye-catching back panel design with gradient finish and the unique diamond-shaped camera module
  • The slim profile of the camera module barely protrudes from the back
  • The in-display fingerprint sensor works well
  • Face unlock is present too, which is reliable (though, not as quick as on the other phones at this price level)
  • Vivid, crisp 6.38-inch full-HD+ Super AMOLED display - the colours are also very punchy thanks to the AMOLED panel, and text and icons are adequately sharp
  • The display gets very bright, making it easily legible even under direct sunlight
  • Widevine L1 DRM certified - you can watch Netflix and Prime in crisp HD resolution
  • Funtouch OS based on Android 9 Pie looks very similar to iOS, and is pretty feature packed
  • Decent performance powered by the Qualcomm Snapdragon 665 - it handles multitasking well and regular usage is smooth
  • Decent set of quad rear cameras - 48MP primary + 8MP ultra-wide + 2MP macro + 2MP depth camera
  • Close-ups are good, with good bokeh and details in objects
  • In bokeh mode, the Vivo S1 Pro's depth camera does a decent job of detecting edges, and blurs out the right areas - colours and details are also good
  • The macro camera is also handy at times, and lets you get very close to the subjects
  • Very good 32MP selfie camera - it captures detailed photos when shooting under ideal light - results are fairly good even when shooting against the light
  • The Vivo S1 Pro packs in a 4500 mAh battery, which easily lasts for 2 days of moderate use
  • Overall, the Vivo S1 Pro is a decent pick if all you want is a stylish design, good battery life, and a punchy display
2-minute Review [Negatives]
  • It's on the cluttered side though, and does have some bloatware - so the experience is not as clean and simple as stock Android
  • More complex games like PUBG though are not smooth at high graphics settings - and here the phone loses out to the best performing phones of this price bracket that pack the likes of Snapdragon 675, and Snapdragon 710
  • The ultra-wide camera provides for versatility in shot framing, but the quality is average - details are low, and the overall image is muted
  • Low light performance is average too
  • Overall, the cameras are decent for the price bracket, but not really comparable to the top camera phones of this price bracket, like Redmi Note 7 Pro, Realme 3 Pro, Realme X, and even the Vivo Z1 Pro
  • Uses the old microUSB port, instead of the modern USB-C port
  • On it's own the Vivo S1 is a pretty good device, but it faces some real tough competition at the moment - the camera and the performance are not the best for the price bracket, though if your main priorities are a best-in-class design, and excellent battery life, it could still make a lot of sense
  • The Vivo S1 Pro feels a little chunky at 8.68mm thick
  • The back isn't glass, as Vivo still uses laminated plastic
  • Having said that, the interface is unnecessarily complicated - swipe-up gesture to access system shortcuts is confusing, since it's in the notification shade in stock or other Android UIs
  • There's a lot of bloatware preinstalled on the Vivo S1 Pro (though the third-party apps can be removed)
  • Heavy games such as PUBG Mobile however struggle to run at a smooth frame rate even at the Low graphics preset
  • This isn't a bad processor, but it's typically now found in phones closer to the Rs. 10, 000 mark, such as the Realme 5i
  • In daylight, the primary camera manage to capture average-looking landscape shots - images lack depth, objects at the sides of the frame also have a bit of grain - HDR kicks in when needed, but the end result isn't always very good - some images have a very cool, bluish hue to them, which look unnatural
  • The wide-angle camera offered a nice perspective, but colours weren't very accurate
  • Low-light photos are just strictly average - focusing is a lot slower in the dark, and it takes a second or two longer to save each photo - there's no dedicated night shooting mode either
  • No option for a background bokeh effect with the front camera
  • Videos can only be recorded at up to 1080p, which is not great, especially at this price - there's no stabilisation either, which is a big letdown
  • Low-light video is not very good, from both primary & ultra-wide lens - has lots of grain as well as weak details
  • Overall, rear cameras are nothing special - you will get better outcomes with the Realme X2 or the Redmi K20
  • The single speaker doesn't get too loud and the sound is a little tinny
  • Vivo uses its Dual Engine Fast Charge feature, but the 18W charger isn't the fastest - charging the phone completely takes about two and a half hours
  • If you'd prefer a more well-rounded phone though, we suggest looking at offerings from Realme and Xiaomi instead, such as the Realme X2 and the Redmi K20, which have much more powerful SoCs
