Extended information:

In terms of photographing, the front and rear 12-megapixel sensors of vivo X21 all adopt dual-core pixel focusing (with 24 million photosensitive units), and the pixel unit reaches 1.28μm, which basically ensures the photographing quality, fast focusing in 1.13 seconds, and an aperture of F2.1 (the front is F1.8).

In the rear position, a 5-megapixel depth-of-field camera has been added, which realizes more gameplay on the camera function of the rear portrait. In taking photos, vivo's X series and Xplay series focus on front and rear photos respectively, and this time the full-screen vivo X21 is even better before and after taking photos.

The front and rear 12-megapixel sensors all adopt dual-core pixel focusing (24 million photosensitive units), and the pixel unit reaches 1.28μm, which basically ensures the picture quality, and the quick focusing in 1.13 seconds, plus the aperture of F2.1 (F1.8 in front), will also perform well in low-light night scenes. On the rear side, a 5-megapixel depth-of-field camera has been added on this basis to achieve more gameplay in the camera function of the rear portrait.
