Critiques pour le/la Vivo X21

vivo X21 Review: A taste of the future
Source: Unbox Anglais EN→FR
That’s a tough question to answer, simply because the X21 is one of those phones that tries to do something new. There is no doubt that there will be more under-display fingerprint capable phones released in the near future as the tech becomes cheaper and more accessible. The X21 is on the cutting edge, though at this point in time the tech isn’t perfect yet.

80% Vivo X21 Review: A surprisingly good package for its price
Source: The Indian Express Anglais EN→FR
Overall, Vivo X21 is a great smartphone for its price. It has 6GB RAM and 128GB storage, which is further expandable using a microSD card. X21 also sports a great design and display, though not ideal for one-handed usage. Hardware, camera and battery performance is decent enough as well.

92% VIVO X21 review – cool in-display finger print technology
Source: Anglais EN→FR
VIVO does really well in offline segment and there OnePlus 6 will not be that easily available, but even if it is, the offline customers are really not interested which one is powerful, which one can shoot better (especially when the difference is minimal), they really don’t care about the hardware but this in-display finger print technology will definitely catch their attention.

Vivo X21 Review
Source: Fone Arena Anglais EN→FR
The Vivo X21 is priced at Rs. 35,990 and is available exclusively on Flipkart online. The X21 smartphone with under-display fingerprint scanner is a welcome change in tech industry and a critical milestone for the company, that eradicates the need for an extra hardware component in the phone.

80% Vivo X21 Review
Source: NDTV Gadgets Anglais EN→FR
The Vivo X21 is the first smartphone with an in-display fingerprint scanner to launch in India. It has decent hardware coupled with Vivo's software, which you might or might not like. The in-display fingerprint scanner works well but isn't in the same league as the physical ones we now have on most smartphones. It is slightly slower to unlock the phone, but not painfully so. This is acceptable considering that the X21 is a first-generation product. On the other hand, opting for a Micro-USB port instead of USB Type-C on a phone priced at Rs 35,990 is a strange move.

Vivo X21 First Impressions
Source: NDTV Gadgets Anglais EN→FR
To keep the smartphone going, Vivo has dropped in a 3200mAh battery which is non-removable. You get a fast charger rated at 18W in the box, which we hope can top this phone up quickly. We will be putting the Vivo X21 through its paces and will be thoroughly testing the new in-display fingerprint scanner as well as all the usual details including performance, battery life, software, and build quality in our full review, coming up soon.

60% Vivo X21 review: The ‘what could have been’ smartphone
Source: Gadget Show Anglais EN→FR
Many a times we see a lot of companies erring big time when sticking a price tag on their devices. It seems like Vivo has fallen in the same trap as the Vivo X21 would have been a good option if the company would have priced it under Rs 25,000. But with a hefty price tag of Rs 35,990, the smartphone is certainly not a great buy. In our opinion if you want to spend this much then you can either go for the OnePlus 6 or the Samsung Galaxy A8 plus smartphones. Both the smartphones offer better processor and have same or more RAM capacity. However, they don’t come with in-display fingerprint sensor. But other than this, both the smartphones are better when compared to the Vivo X21. A better price point and the Vivo X21 could have been a far better smartphone than it actually is.

75% Vivo X21 review: Through the looking glass
Source: India Today Anglais EN→FR
The Vivo X21 is a device straight out of the future. There's no denying that. Its in-display fingerprint scanner is a technology to marvel, in 2018 when no-one else is doing it (at least not yet), and even though it isn't perfect, the X21 sets the stage for the future. That's saying a lot about Vivo, a company that has for long been called, a cheap iPhone rip-off maker. While it's still blatantly copying the iPhone, phones like the X21 show that, it is also forward-thinking. And in the world of technology, that is all that matters.

Not so long ago, the Chinese smartphone manufacturer, Vivo showcased their innovation on the Vivo X21 UD, a smartphone that comes with an under display fingerprint scanner. Now the same smartphone has been entered in India as Vivo X21. Vivo X21 (known as Vivo X21 UD in China) is the world’s first smartphone to feature an in-display fingerprint scanner.

Vivo X21 review: Fast and fun, but not without compromises
Source: Android Authority Anglais EN→FR
The Vivo X21 is a fun device that gets a lot of things right. The display is a joy to look at, performance is solid, and the fingerprint sensor and facial recognition work well. It looks great, and most of the times it works just as well. It’s let down by the software, which lacks polish and attention to detail, and comes with several UI elements that just don’t make sense.
