Vivo X21, the smartphone with an in-display fingerprint sensor, is now official. The X21 is the first commercial device with an in-display fingerprint sensor to become available in India. The smartphone has been launched at Rs 35,990, and will be available exclusively on Flipkart.

With X21, Vivo is showcasing how it has taken a leap in terms of technology and is not shadowing other tech players in the smartphone industry. While Vivo had first showcased the in-display fingerprint sensor at Mobile World Congress in Shanghai last year, the first product came out in the form of X20 Plus UD early this year. However, the Vivo X21 is the first device to go on retail sale, and it is the one that will make the technology mainstream.

Since Vivo X21 brings a new technology to the forefront, it is priced slightly on the higher side of the price spectrum. However, when seen from a technology perspective, Vivo is offering a feature that is set to become commonplace on smartphone from Chinese brands as well as mainstream brands like Samsung and Apple. If you plan to invest on that technology then here the top five features that you need to know about:

Vivo X21 in-display fingerprint sensor

This is the unique selling point of the smartphone. The Vivo X21 is the only smartphone in the country to feature an in-display fingerprint sensor. As smartphones are getting bigger displays with thinner bezels, smartphone makers have been finding new ways to accommodate the fingerprint sensor. While rear-mounted fingerprint sensor is a viable solution, it often comes at the cost of design. With an in-display fingerprint sensor, smartphone makers can offer standard experience without any hindrance to the design.

Vivo X21 uses an optical in-display fingerprint sensor placed below the surface of the display. It captures reflected fingerprints between and through the pixels of the OLED panel. There is no word on the resolution of the reader, but Vivo says it has less false rejection rate compared to conventional technology.

Vivo X21 notched display and ergonomic design

Vivo X21, being a modern smartphone, has very thin bezels surrounding the display. The smartphone features a 6.28-inch AMOLED display with a resolution of 2280×1080 pixels, and supports a taller 19:9 aspect ratio. Vivo has achieved the taller aspect ratio by adopting notched display design, which allows for thinner top bezel and hides the front facing camera, microphone and other sensors.

While the Vivo X21 does not feature an edge-to-edge display design like the Apple iPhone X, it does have smaller chin than conventional smartphones in the market. It also features a 3D curved back design for ergonomic fit, and a clean design with vertically stacked dual rear camera system at the top-left corner.

Vivo X21 dual rear cameras

Vivo is known for cameras, and the new X21 features dual camera system at the back. There is a combination of 12-megapixel and 5-megapixel sensors. The primary 12-megapixel camera uses a dual pixel sensor with f/1.8 aperture. The dual pixel system allows for faster auto-focus, and is a feature not available even on flagship devices. Vivo is using the secondary 5-megapixel sensor for depth-sensing which will help in portrait mode and producing bokeh effect.

There is also a 12-megapixel selfie shooter with dual-pixel sensor. The sensor should allow for faster autofocus and sharp selfies even in low-light conditions.

Vivo X21 performance

While one would expect a Snapdragon 845 chipset in this price segment, the Vivo X21 is using a Snapdragon 660 SoC instead. The Snapdragon 660 is one of the first in the Snapdragon 600 series to use Qualcomm’s Kyro design for individual cores. It has four Kryo 260 power cores and four Kyro 260 efficiency cores. It also offers 6GB RAM and 128GB storage as standard, which should handle most talks effortlessly.

Vivo X21 software

The Vivo X21 also comes with Android 8.1 Oreo layered with Funtouch OS 4.0. The latest operating system ensures secure experience, and protection against new malware. While Vivo does not have a proven track record for software updates, the Vivo X21 should be one of the first to get update when the company rolls out Android P.
