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	Eye-catching colorway (plastic) design that is unapologetically flashy - this one is sure to turn heads Dedicated Google Assistant button on the left side Fast, accurate in-display fingerprint scanner and face unlock options Beautiful, full HD 6.38-inch Super AMOLED panel - you will get punchy colours, deep blacks, and good sunlight legibility It also has Widevine L1 support which means you’ll be able to stream videos in Full HD on video streaming platforms like Netflix and Prime Video An interesting addition to the display on the Z1x is the new low brightness anti-flicker mode - when switched on, it reduces screen flicker to alleviate visual fatigue - particularly useful during late-night gaming sessions Funtouch OS is an iOS-look-alike that is filled to the brim with customizations It now also packs a useful Dark mode There is also a dedicated PUBG feature (apart from the separate dedicated Gaming mode) that helps users make the most of their time while in the waiting room (Users can quit the application while waiting for the game to start and the game timer is displayed as a chat bubble in the UI) Very good performance backed by the excellent Snapdragon 712 SoC that powered its predecessor - gamers too won’t be disappointed - the phone is more than capable of playing heavy games, at top graphics settings Thermal management is pretty good too and the phone does not warm up easily Very good set of cameras - front and back - you will get good detailed pictures in all lighting conditions On the rear, the Z1x houses a triple-camera setup that consists of a primary 48MP sensor, an 8MP ultra-wide camera and a 2MP depth sensor The pictures from the primary camera are visually appealing, generally saturated, and the colours pop The wide-angle camera also takes images good enough to be shared on social channels The camera application is also pretty comprehensive and houses a dearth of other features like Fun Video and AR stickers There is also a a dedicated night mode present which does help in balancing exposure and getting a bit more detail in low-light scenarios Portrait shots come out reasonably well - with good subject separation The selfie camera is a 32MP snapper and takes really good selfies, especially in good light - there’s an AI Beauty mode too that lets you change just about any feature of your face - you can also play around with a bunch of different portrait effects and edge detection on these portraits is pretty decent too Decent video recording quality - 1080p videos are stabilised well and colour reproduction is also decent (though focus lock can sometimes be jittery) - 4K videos, on the other hand, are a bit jerky Overall, this is a very good camera setup for the price - perhaps only a shade behind the top camera phones of this price bracket - the likes of the Realme X and Redmi Note 7 Pro Reasonably loud speaker (though, of course, as usually expected in this price range, it lacks depth) Very good battery life with a large 4500mAh battery - you can easily get 1.5 days of use Vivo has amped up charging speeds on the Z1x too, compared to the Z1 - the phone now supports 22.5W vivo FlashCharge that takes about 1 hour and 20 minutes to completely charge the phone from the 15% mark Overall, Vivo Z1x presents itself as another excellent all-rounder alternative from the Vivo camp for the mid-budget segment after the successful Vivo Z1 Pro - it stands up to the likes of Realme X, Oppo K3, Redmi Note 7 Pro, the Samsung Galaxy A50 - all great phones on their own accord
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	On the bulky side It still continues to be one of the more cluttered Android UIs however, and can prove to be overwhelming for someone coming from a lighter/stock UI
