Chinese smartphone brand Vivo is working on a new smartphone that comes with a colour changing glass. As per a report by Android Authority, the phone comes with electrochromic glass at the back that changes colour with a push of a button. Vivo has not made this phone official yet and nothing much is known about the device apart from the colour changing glass.
A electrochromic glass backplate changes colour when the voltage is changed. It is not yet clear as to whether this will affect battery life of the device or will it increase the temperature of the device. A similar technology was earlier seen in the OnePlus concept phone, where it used the electric to change the opacity of the glass to hide the rear camera when not in use.
