2-minute Review [Positives]
  • 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
  • Beautiful, attractive, premium glass design (Gorilla Glass 5 on the front and back), with a modern gradient finish at the back - identical to the Realme XT
  • The phone is also marginally smaller than the Realme X and is lighter too at 183 grams, which gives it a very balanced in-hand feel
  • The glass on the back is of the glossy kind, but it barely registers any fingerprints or smudges and it isn’t very reflective
  • The in-display fingerprint sensor is snappy (the fastest in this price bracket), as is the facial recognition
  • Excellent 6.4-inch FHD+ (1080x2340) Super AMOLED display with a dewdrop notch - again same as as the Realme XT - it has vibrant colours, deep blacks, good sunlight legibility, and good viewing angles - one of the best displays of this price range
  • Also comes with Widevine L1 standard, which means videos on platforms like Netflix and Prime can be seen in crisp HD resolution
  • ColorOS is fairly streamlined, and packs fast animations that help the phone feel snappy - there are of course several add-on features too, compared to what you would get in stock Android
  • The UI also isn’t ad-strewn as recent Xiaomi phones have tended to be
  • Excellent, butter smooth performance backed by the powerful Snapdragon 730G (15% faster than the Snapdragon 730 in graphics performance), which makes the Realme X2 one of the best-performing phones in this price range, especially for gaming - even ahead of the Redmi K20 in benchmarks - the Realme X2 breezes through pretty much any task you throw at it and is also an excellent smartphone to game on - even heavy games like PUBG Mobile, COD Mobile run consistently smooth
  • Very good quad-camera setup at the rear - 64MP primary + 8MP ultra-wide + 2MP macro + 2MP depth sensor
  • The primary 64MP camera works (by default) on a 4-in-1 pixel binning technology that combines four 16MP shots to offer one bright and detailed photo
  • The primary camera capture some really attractive photos in daylight, offering good brightness and clarity - with HDR enabled, the camera offers a wide dynamic range
  • The ultra-wide-angle camera comes in handy if you want to capture a wider frame of view or want a different perspective on the subject (but there is some noise even in daylight conditions)
  • The camera also supports Nightscape (Night mode), which comes in handy in low-light conditions, and helps improve picture clarity
  • The Realme X2 also does a very good job when using Portrait mode - edge detection is excellent thanks to the dedicated 2-megapixel depth sensor and details are crisp
  • Good video recording quality - image quality is good, and there is also stabilisation at 1080p (but not at 4k) - video bokeh feature also works very well and it can maintain a very accurate edge detection with busier backgrounds (low light video recording could have been better though)
  • Very good selfies from the 32MP front camera - it captures very good portrait selfies with crisp edges and background properly blurred - there is also night mode for selfies and it works pretty well
  • Overall, Realme X2 has one of the best cameras under 20k category, arguably right behind the Redmi Note 8 Pro & Redmi K20
  • Good speaker - verbal audio sounds clear enough even in max volume, and the audio is loud enough for you to hear the phone ring from another room
  • Good battery life with a large 4000mAh battery - you will get about 1.5 days of moderate use
  • There is super-fast, class-leading 30W VOOC 4.0 fast charging support - you can charge up the Realme X2 from 0 to 100% in an hour with the supplied charger
  • Realme has yet again managed to craft an excellent package with the Realme X2, especially if you want to do heavy gaming - Realme’s strategy of bring high-end features like the 30W VOOC Charging & in-display fingerprint sensor to a mid-range phone makes the Realme X2 a very compelling phone to buy
2-minute Review [Negatives]
  • 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
  • There is, as usual, some bloatware that comes pre-installed (but most of it can be uninstalled)
  • The macro lens is ordinary - you will be able to get really close to the subject, but detail levels in the images are low
  • Having said that, the competition is neck-to-neck - there is Redmi K20 which offers a full notch-less display, even more polished design and slightly better camera at a similar price (at the cost of slower 'fast' charging) - and if you are on a tight budget, the cheaper Redmi Note 8 Pro is also a very good option as long as you don’t care about the AMOLED display and an in-display fingerprint sensor
