The iPhone-ish notch has recently become increasingly common, with the smartphones of Huawei, OPPO, Xiaomi and several others copying the Apple designs. The latest in the list is Vivo X21, and we received info on its launch date and several specs. Vivo X21 is set to launch on March 19 at an exclusive conference. We as well know that it will have four variants: X21, X21A, X21 UD and X21A UD (or X21 UD A). These smartphones are supposed to bear Super AMOLED full screen. This will, of course, include the narrowed chin and forehead as found on iPhone X. The phones are also to consist of a vertical layout for dual camera setup, again like iPhone X. Other features include 18W fast charging, Snapdragon 670 or 700 chipsets, and Funtouch OS based on Android 8.0 Oreo. 4GB RAM and 64GB internal are expected, likely in the Vivo X21 itself. Storage capacities for its three other variants are yet unknown. Vivo X21 is likely to have a 6.43-inch screen.
