The phone design
Vivo X21 is a mid-range device and it features a metal unibody design with a layer of 2.5D glass on top for durability and touch sensitivity. The top and bottom of the front side are completely flat and rest directly on the body. There is a small notch at the top of the display which houses the selfie camera, a couple of sensors, and earpiece. The only other sensors present at the back of the device are a single 16-megapixel camera and the fingerprint scanner. The back cover is glossy but it easily picks up fingerprints and smudges.

Camera quality
Vivo X21 can shoot up to 16 MP photos and there is an 8 MP selfie camera at the front. The camera performance is fairly decent and is pretty comparable to what other smartphone manufacturers offer. We were quite impressed with the camera, considering that it has a small single lens with dual pixels. The colour accuracy and dynamic range, as we experienced during day and night, seemed to be consistent. The colours did look good and the pictures had good exposure and we did not have to adjust the settings too much to get good shots. The performance at night was also good, the HDR quality seems to be strong and the white balance works really well. Vivo has also added a “flash sync” function that helps you take better pictures in low-light situations.
Battery life
We had a brief time with the phone and it seems as if this technology is still far away from widespread usage in smartphones. The Vivo X21, though, is up to par in this department and comes with the same 3,200mAh battery as the predecessor X20 Plus UD. Verdict The Vivo X21 marks a real step forward in smartphone design. It still has a premium feel in the hand, the screen is sharp and vibrant, and the new fingerprint sensor works without too much fuss. The phone will go on sale in India next week at a starting price of Rs 35,990. While the Vivo X21 certainly is one of the most promising looking smartphones this year, it does suffer from a few limitations that are hard to ignore.
