After the X20 Plus UD, the Vivo X21 is the second Vivo’s smartphone to feature an in-display fingerprint reader. Thanks to a very innovative chip released by Synaptics, if you own this phone you can unlock it through fingerprint recognition by simply touching the display. So, the sensor is embedded right into the display as there is no space for a Home key due to the full bezel-less design. However, in-display fingerprint readers are slower and less efficient than the traditional fingerprint readers which often put them at an operational disadvantage.
A new update which has just been rolled out on the Vivo X21 is now improving the fingerprint reader experience by making it safer and more efficient. According to the official changelog released, the new update will improve the fingerprint reader processing logic, improving the security and efficiency of the authentication process. The improvements to the fingerprint reader are not the only ones implemented through this new update of Funtouch OS (the customized Android fork made by Vivo). With this update, the company has added sticky notes and made some optimizations to the driving mode making it more user friendly.
Further, the update brings Funmoji, a set of customized emojis working through AR. In a similar way to Apple’s Animoji, the user can create emojis based on its facial expressions. The update rolled out on Vivo X21 also contains optimizations to the system layout and to the icons’ priority in the status bar. There are also some improvements with regards to the system resource scheduling mechanism and the system stability and efficiency. Given its size, we suggest you to download the update while you are connected to a Wi-Fi network.
