Vivo announced the X21 in two variants, one with a normal fingerprint sensor, and the other one with an under-display fingerprint sensor, but both were powered by Snapdragon 660 along with dedicated Qualcomm AIE Artificial Intelligence Chip. Now the vivo X21i has been certified in China, after a recent rumor, which will be powered by MediaTek Helio P60 12nm SoC. This also has a 24-megapixel front camera.
