Vivo X21 comes as a progression from the Vivo V9. Priced at 23,299, the phone will not look any different from the V9 but does have one specific change.
Vivo X21 comes with the new In-Display fingerprint scanner which works brilliantly and is quite futuristic. However, it does not have many changes from the V9, making it more of a rehashed phone rather than a newer one.
