Vivo X21 Review

Extra highlights of Vivo X21 are Funtouch OS 4.0, 32-bit/192kHz sound, Active clamor wiping out with committed mic. Vivo X21 has GPRS, EDGE, 3G, WIFI, Bluetooth, GPS network choices on board.


With Vivo V9 out in showcase only for two months, Vivo chose to dispatch yet another of their lead gadget. This time, one which accompanies some minor redesigns from past models, and a component we have never observed on any cell phone gadget, an in-screen unique finger impression scanner. Telephone is valued near OnePlus 6 and Huawei Honor 10, so the inquiry remains, is it worth its cost and is it worth an overhaul from past Vivo V9 which seems to be indistinguishable to this one? How does in-screen unique mark scanner tech work in everyday utilization? We should discover.


Vivo X21 appears to be like Vivo's V-arrangement lead, Vivo V9. Telephone includes an all-dark aluminum outline and a glass back with decreased edges, which make it exceptionally agreeable to hold. It's around 7.5 millimeters at its thickest point, yet it's shockingly simple to deal with, particularly considering extensive 6.28-inch screen. It has a glass and metal outline, which clearly is strong to hold. It is thickly assembled and glass back feels solid as well. There's almost certainly that telephone looks like Vivo V9, yet there's not a single unique mark scanner in sight on back. To be completely forthright, if Vivo would've named it V9 Pro, that would've had no effect.

Front of gadget is fascinating, as it was on Vivo V9. Its majority is secured with edge to edge show, which has a score. Score holds earpiece and sensors, together with forward looking camera. There's a slight button at base and insignificant bezels at sides, yet rest of front is altogether secured with screen.

At back of gadget, you'll locate a double camera setup vertically put on upper ideal with a LED streak just underneath. It's very little contrasted with other vertically put sensors. There's a sharp, thin edge around camera, however it's very unobtrusive and shouldn't get scratched when put on harsh surface Vivo gives a plastic case to ensure body in any case. Back is secured with glass, giving a top notch feel and look to it. It sparkles well, however not as much as Mirror dark complete on OnePlus 6. You'll see some Vivo marking in center of telephone and some minor written work on base part, with rest of back kept perfect and straightforward.

One thing that numerous individuals will see is that there's not a single unique mark scanner to be seen on this telephone, and this in light of the fact that Vivo X21 accompanies an in-screen unique finger impression scanner, first in any cell phone.

An appreciated plan choice is consideration of 3.5 mm earphone jack which is currently found over telephone. On right half of telephone, you'll discover a power catch with volume keys with left side kept clean. At base, there's a solitary base terminating speaker, sim plate and a Micro-USB port, which is a bummer as most telephones currently accompany USB Type-C rather, particularly at this cost.

All things considered, generally speaking look and feel of the telephone isn't terrible at the cost. On the off chance that you take a gander at the OnePlus 6, there's a ton of likeness between the two and even the quality isn't imperiled. Be that as it may, this plan is dull and the vast majority will expect something new in outline branch of Vivo X21.


Vivo X21's show is straight out excellent. It's a 6.28 inch Full HD+ AMOLED show with a goals of 1080x2280p, angle proportion of 19:9 and pixel thickness of 402 ppi. Screen is an OLED board which implies it has dynamic shading palette and inky blacks. Symbols simply pop, particularly when you utilize a pleasant dull foundation.

A vital point about Vivo X21's show is that it is splendid. Indeed, even telephones like Google Pixel 2 truly battle with no attempt at being subtle, particularly while showing darker pictures or UIs. Interestingly, I could utilize Twitter's dim UIs without stressing my eyes on Vivo X21. At some occurrence, Vivo X21 looks considerably brighter than Samsung Galaxy S9+.

Something else to discuss is score on screen. It breaks all-screen hallucination, however in any event it's genuinely little. It frequently vanished into dark outskirt around it yet notwithstanding when it didn't, I scarcely saw it. Just issue is that it takes land from status bar, which makes it substantially less valuable and shockingly, you don't get a choice to turn it off as you do on some other Android cell phones conveying indented shows.

Vivo X21 likewise includes a dependably in plain view that looks really like Samsung's usage. It even offers a Side Clock variant, however telephone doesn't have bended edges of Samsung's leaders. You can redo shading and foundation of dependably on clock, yet you can just pick to see notices for missed calls and messages, not messages, or different sorts of warnings, which is very frustrating. Regardless of whether you empower Always in plain view or not, Vivo X21 dependably demonstrates a unique mark symbol when screen is killed. This is so you know where installed unique mark sensor is. Symbol likewise flies up when you have to confirm in applications that utilization unique mark scanner. I am interested to perceive how the Vivo X21 passages inevitably, in light of the fact that that dependably on unique mark symbol could cause consume in. I haven't seen any issues up until now, however it's something to watch out for.

In show Fingerprint scanner

Vivo X21 is the primary business cell phone with a unique mark sensor underneath its screen. It doesn't seem like a major ordeal, as most non-nerd individuals aren't inspired, yet it is.

Telephone producers and part providers have been chipping away at this innovation for quite a long time. Presently, Vivo and Synaptics have at long last broken the issue, far and away superior, Vivo beats enormous young men too, for example, Samsung and Apple, who still can't seem to discharge telephones with in-show unique mark scanners. Huawei just did it on amazingly costly Huawei Mate RS, declared not long after the Vivo X21.

Put essentially, Vivo inserted a thumbnail-sized sensor on back of telephone's OLED show. Light from OLED show ponders minute edges and valleys of your unique mark and achieves sensor through little holes between show's pixels. It likewise works incredible more often than not. Simply contact it like a standard unique finger impression sensor and telephone opens itself in a brief moment. It's solitary insignificantly slower than a traditional scanner and you don't have to press harder than common, however it helps in the event that you put your entire unique mark on screen, not simply tip.

Be that as it may, this is unmistakably first-gen innovation. It doesn't generally take a shot at first attempt and every so often it requires numerous presses to enroll and open. A few times, telephone even requesting that I enter my PIN, after different fizzled endeavors to utilize enrolled unique finger impression. It's likewise conflicting, as once in a while telephone opens super-quick, while different occasions you have to press and hold for over a second.

Vivo will no uncertainty fathom these issues inside a few years, yet at this moment, inserted unique mark innovation isn't as dependable as regular sensors. In the event that you purchase Vivo X21, have a little tolerance.


Vivo X21 is fueled by Snapdragon 660 processor and Adreno 512 GPU, combined with 6 GB of RAM with shrivel 64 or 128 GB of on-board stockpiling. Telephone likewise underpins outside memory extension through Micro-SD card space, so coming up short on memory on this telephone won't be an issue.

For most part, Vivo X21 figures out how to convey astonishingly and functions extremely well. To the extent every day errands are concerned, things feel smart and there is actually no slack anyplace. Execution is like that of Nokia 7 Plus, which includes a similar processor. Be that as it may, additional 2GB of RAM on Vivo X21 gives it an edge over Nokia 7 Plus. With respect to illustrations serious undertakings, Vivo X21 is certainly not the best telephone out there, but rather it's not awful either. Telephone could deal with PUBG on medium settings and a higher framerate, which is very great. Likewise, while I've already had inconveniences on Vivo V9 drive stopping applications in foundation, I confronted no such issues on this telephone, which to me is again incredible.

On equipment level, Vivo appears to have settled on some great choices and some awful. While telephone holds 3.5 mm earphone jack, it trench USB Type-C port once more, for an obsolete smaller scale USB port. This gives contenders of this gadget and edge over it as they will have the capacity to exchange information and charge considerably quicker than Vivo's most recent leader. There's no stereo speaker bolster discovered either, and in the event that you get your telephone wet, you will be up the creek without a paddle as it doesn't accompany residue and water safe.

Indeed, even without stereo speaker bolster, speaker on this thing is quite uproarious also and is useful for amplifier calls and in addition not too bad media utilization. It isn't the loudest out there, yet in any event the levels are adjusted, which, as I would see it, is the thing that issues more. Vivo additionally gives a couple of headphones inside the crate, which is something I truly respect.

In general, it appears as though Vivo focused on the vital equipment highlights, for example, a quick processor and sufficient RAM and forfeits on different highlights which you may see on other Android gadgets in this value go.


Vivo X21 packs in a non-removable 3,200mAh battery, which appears to be just about right. Because of intensity effective Snapdragon 660 processor locally available, I could get a tolerable measure of battery life. In my testing, gadget effectively figured out how to last a whole day of normal utilization, which included playing a touch of PUBG, browsing my messages, including heaps of stories Instagram, and tuning in to some music on SoundCloud.

Likewise, with regards to charging, in spite of wearing a smaller scale USB port, it supports quick charging. Telephone charges from 0 to 100 % in less than 110 minutes, which is really great. While it's not the speediest charger out there, it unquestionably draws nearer to enormous mutts in showcase.

In the event that you depend vigorously on your telephone are a stuck to it then you may require a charging point following 8 to 10 hours. The great part is that the cell phone accompanies quick charging help which implies that the gadget can energize before long. Be that as it may, it would have valued significantly more with a bigger battery.


Vivo X21's camera setup is like what you will discover on Vivo V9. It is a double camera setup comprising of a 12 MP principle sensor and 5 MP optional sensor with f/1.8 and f/2.4 opening individually. Camera is a minimization in the event that you consider megapixel check however it's an overhaul for better low-light photography.

Amid my underlying camera test, results end up being persuading. I tried it in light and it demonstrated guarantee, be that as it may, on occasion pictures looked falsely upgraded. Telephone utilizes a monochrome focal point to click picture photographs, and enables alteration of obscure to reinforce or help the impact. It utilizes AI to isolate foundation from subject in forefront while utilizing representation mode. Edge identification may not be flawless but rather it is still truly great. Camera shot some respectable and tasteful pictures when I took representation shots. Bokeh impact isn't that awesome and on numerous events camera obscured both the subject and foundation. Picture nature of pictures caught in sunlight ended up being great however they ended up being grainy and loaded with commotion when light gets diminish. Additionally, Phase discovery self-adjust isn't up to the stamp and I frequently moved precarious shots of subjects.

Raise camera took great pictures in respectable lighting conditions while astonishing me with its HDR mode. HDR mode figured out how to deal with complex scenes with greatly splendid and dull zones figuring out how to adjust the whole scene. There was some clamor and Vivo X21 is no Samsung Galaxy S9 or Google Pixel 2 with regards to catching surfaces, however it was by and large great. A positive side to see was that screen speed and picture handling stays smart on Vivo X21. Dissimilar to other Chinese gadgets, including some from Vivo, that just makes the pictures delicate for reasons unknown, the Vivo X21 figures out how to deliver incredible outcomes.

Vivo X21 shoots recordings up till 4K at 30 fps, which is genuinely better than average at a telephone at this cost point. Camera needs Optical Image Stabilization and Electronic Image Stabilization so film turns out quite temperamental, particularly in 4K. At 1080p, however, Vivo X21 figures out how to catch some better than average recordings with exact shading multiplication and great powerful range when contrasted with more seasoned Vivo leaders.

Front of Vivo X21 houses a 12MP selfie camera with f/2.0 opening. Camera application on telephone has an exceptionally basic UI. As it is a Vivo telephone, it is compulsory that it accompanies a marvel mode and with it, you can catch a selfie or a representation and afterward improve it by smoothening skin or evacuating wrinkles. Camera programming manages to give a scope of choices to control camera and watermark pictures. Both the front and also back camera bolster representation mode and HDR modes. Clients can likewise shoot 'Live' pictures utilizing 'Live Photo' mode.

Generally speaking, it's a not too bad camera, something you will expect on a midrange cell phone gadget. While it's not awful, there are a lot of different telephones in showcase with better cameras in this range so Vivo needs to address this issue in their next cycle.


Coming to programming, Vivo X21 keeps running on Android 8.1 Oreo finished with organization's own layer of customization by means of FunTouch OS. Telephone has indistinguishable User Interface from other Vivo cell phones. Vivo has taken a few parts of iOS, for example, shape and look of symbols, nonattendance of application cabinet, brisk settings at base of screen, and so on. I'm by and by not an aficionado of brisk settings on Android telephones and on Vivo X21, fast settings menu was not effectively open. Ordinarily I needed to swipe three to four times to get hold of menu.

Vivo X21 accompanies a motion mode which enables clients to explore through it with the assistance of signals simply like on Apple iPhone X. In motion mode, screen is isolated into three sections: Swipe up on right side to open control focus, swipe on focus to return to home screen and swipe up on left to return one screen. In the event that you swipe on focal region at that point screen enables you to look through dynamic applications. Status bar is somewhat chaotic as score covers a considerable measure of territory and remaining isn't been used extremely well. Notice bar has an extremely shortsighted UI and one needs to tap on it to peruse finish data which can be a mood killer for some clients.

Launcher is additionally truly fundamental and there is no application cabinet which implies that all your applications will be set on numerous home screens. Aside from this, it has every single standard element of Android 8.1. With Vivo X21, organization is additionally concentrating a great deal on the Music and sound involvement of cell phone. Gadget comprises of a "Hello there Fi" DAC on board and has a mono speaker situated at base of gadget. Sound is acceptable, however, and nothing awesome.

It is a product encounter which most Vivo clients and fans know about and they won't be overwhelmed with anything on Vivo X21's product. For stock Android fans, programming on Vivo X21 is a gigantic no go region.
