When you see the VIVO X21, you’ll think that this is just another in a long line of phones with notch displays. However, the telephone is literally hiding something in plain sight: an invisible fingerprint scanner that sits underneath the display!
This is brand-new tech developed by Synaptics (yes, the same notebook touchpad guy) and it requires the use of an amoled display since it takes advantages of the gaps between pixels to scan the fingerprint. It wouldn’t work with traditional LCDs because.
The very first question is why. When smartphone bezels started shrinking, most telephones shifted the scanner into the rear panel. You may even be utilized to it on the back. This technology brings it back to front so that you can unlock your phone whenever it’s on a desk. It helpfully exhibits a dim fingerprint on the display as soon as you get close to it.
The telephone is largely unremarkable except for that in-display fingerprint scanner. This is officially the very first phone to market with this kind of fingerprint scanner and this is probably the main justification for this price.
When compared with the more conventional capacitive type of fingerprint scanner (which was perfected over many versions today ), this is only the first generation. Which means you can find kinks. It takes significantly longer to enrol a fingerprint. As an example to read correctly, you need to press on the display fairly hard. Other hygiene features incorporate the dual back camera (with live picture, portrait styles ), curved glass back, 3.5millimeter headphone jack and fast charging. Fortunately, all of them can be uninstalled. If you want a stock Android experience, look elsewhere.
Price: ₹ 35,990
On the plus side, there are tons of options for customisation, call recording, OTG, navigation gestures (it’s possible to switch off the Android buttons), movement gestures, split screen, one-hand mode, dual apps and game style.
Camera performance is pretty good — quite like this Vivo V9 in fact. Except for the V9 prices just Rs 23k. Battery life is all about a day and it costs fast. All said and done, the in-display fingerprint tech is a big conversation starter and it looks really cool. However, it should not be your principal consideration (especially due to the caveats).
At around the same price as the X21, you’ll be better off using all the OnePlus 6. OnePlus is providing you with a flagship Snapdragon 845 chip, stock Android experience, a much better camera with optical image stabilisation and way better battery life.
