Right
after OPPO teased its upcoming R15 and R15 Plus, Vivo X21 has received the
official Chinese 3C certification. According to the listing, the upcoming
handset will be released in four different variants: Vivo X21, X21UD, X21A and
X21 UD A. We guess that the first two variants will be the most powerful and
expensive ones, while the third and the fourth one will be their affordable
alternatives.
The two UD variants will feature an under-display
fingerprint scanner just like the Vivo X20 Plus UD, thanks to the chip launched
by Synaptics around the end of 2017. So, with the Under-Display versions of the
Vivo X21, it will be possible to unlock the phone just by touching the display.
According to the latest rumours, the device will have a custom borderless
display supplied by Samsung. At least the first two variants of the handset,
i.e. the X21 and the X21 UD, are expected to come with the octa-core Snapdragon
670 SoC by Qualcomm.
This processor is still not official, but given that
Qualcomm has just announced the Snapdragon 700 series at MWC 2018 we guess that
SD670 too will be unveiled soon. Vivo X21 is also tipped to come with 18W fast
charging, but it was expected given that Snapdragon 6xx usually support
Qualcomm’s Quick Charge technology. We do not know whether the X21 and X21 A
will come with a notch.
