Vivo is one smartphone brand that is always bringing new innovations ranging from in-display fingerprint scanner to lightning-fast charging tech to placing a gimble in the camera module. The latest addition to their list of innovations is a smartphone rear glass that changes colour, unlike other phones (Samsung Galaxy Note 10, OnePlus 8 and others) where you have to change the angle to experience the colour change.

In a video spotted by Android Authority on Weibo, the mystery phone’s rear glass changes colours with a press of a button. According to a tipster, Vivo has been able to achieve these results by using an electrochromic glass backplate which tweaks colours according to the voltage with the help of a colour-morphing material. As observed in the concept video, the phone’s colour is sapphire blue at the start but it changes to a more silvery finish when a thumb is placed. However, one big question is whether it will affect the battery life of the phone or not. The machine translation indicates that it was designed keeping power consumption in mind so that it does not drain the battery.
