With a drop in light, the photos start showing grains, unless you have enough light sources to help the camera even out the irregularities.All-in-all, the Vivo X21 is a tough option to recommend, especially when the OnePlus 6 — one of the most powerful smartphones out there, is shockingly close to the same price tag.Bokeh shotThe bokeh effects in portrait photos are good, with a well-managed distinction between the subject and the background. The upside to this setup is that it unlocks the phone in an instant, even when there’s not enough ambient lighting. many-a-times it does not detect at first try, needs to be firmly pressed down, and cannot be used with wet or dirty fingers. Once you tap on it, it brightens that patch, throwing as much light possible as it can on the finger&OEM 20L knapsack agricultural battery sprayer39;s surface.
The 9V/2A charger topped the battery from 50 per cent in around less than an hour, which was impressive. It looks good, has a playful OS with multiple features that most serious performance-oriented phones don’t consider offering, and has all the essentials measured in the right amount you expect from a premium smartphone.Overall, the X21’s camera is good for casual users, but don’t expect an equivalent of Google-Samsung performance here.Cons: Slow fingerprint scan, midrange chipset, bloatware and expensive.(source) # . To the rear are 12MP + 5MP dual cameras, with the second sensor meant to assist bokeh.Pros: Performance, in-display fingerprint scanner, camera and design.8 and has a 1/2.Battery:While being packed to the brim with one of the latest technological achievements, Vivo’s flagship also impresses us with its battery life. The details are well-captured too. The camera app offers several AR stickers and iOS-inspired live photos as well, which is certainly not a bad for the shutterbugs looking to update their social media timelines.The technology sounds promising, but it’s still a first generation product. The sensor also has other limitations too — the success rate isn’t accurate. In fact, throughout our time with the X21, we seldom got the opportunity to rely solely on the fingerprint sensor. Under broad daylight, the camera performs really well. It also offers flagship specifications with an almost-stock Android UI.Camera:Vivo focuses on camera’s performance a lot and the X21 is a shining example of that. All this time, we have been pretty happy about OnePlus’ Face Unlock system, praising it for its fast response and accuracy. We can safely say that the Vivo X21’s face unlocking as fast as the OnePlus, making it one of the only smartphones with the fastest face unlock out there.
However, the end result still cannot match up to Google’s Pixel 2 or Samsung’s S9. The 3200mAh reservoir manages to stretch out for a day, with 20-30 per cent of juice left. The camera can scan faces using 3D depth mapping, which is certainly better than the 2D face unlock system seen on a majority of Android smartphones. It is a perfect example of what an Android phone can be when the developers are given a free hand. The X21 is more than the sum of its gimmicky features, delivering on where it matters for the casual smartphone seeker — aesthetics, performance, camera and battery.However, the Vivo X21 is a smartphone that will probably bring out the 9-year-old in you. The 12MP front camera is also efficient in snapping good looking selfies, with Vivo’s camera algorithms trying their best to deliver edit-free shots.
The photos contain an impressive amount of colours with the right balance of contrasts. What pulls down the Vivo from beside the OnePlus is the difference in core chipset performance and operating system gimmicks. Compared to this, the Vivo X21 could only brag about the in-display fingerprint sensor, which is still in its early developmental phase. There are drawbacks for sure — Though optimised, the OS is unnecessarily complicated and modified, and the presence of a micro USB port irks those who want the latest in their premium smartphone. Since it’s a premium smartphone, Vivo has packed in fast charging capability to please the backpackers. The primary sensor has an aperture of f/1. Vivo’s Face Wake takes it a step further by utilising an IR fill light for helping the camera to unlock in dim lit scenarios. The reflected light carries the pattern of the fingerprint back to the sensor, which is then used to authenticate the unlock request. Details are also lost in such situations.Conclusion:The Vivo X21 is definitely a well-engineered smartphone. Therefore, it’s noticeably slower than the capacitive counterpart one would find in other phones today.In this case, the X21 always highlights the patch on the display where the sensor is placed.5-inch sensor, assisted by PDAF.However, the Face Wake facial recognition system is a gem of a biometric verification system. We assume it will better in time.However, the biggest drawback with X21 is its price and puts it up right against its mighty cousin — the OnePlus 6, which currently prides itself to be one of the fastest Android smartphones on an affordable price. Vivo should be proud of their Face Wake system and should surely invest more behind it to bring it up to the benchmark
