In the near future, mobile phones with a changeable color on the back may be launched.
According to Report, a user named Ice Universe shared this information on Twitter:
"The owner of a mobile phone brand is developing a cell phone with discoloration rear case and adjustable color change speed. Maybe in the future, smartphones with only one color will be replaced by changeable colors."
Another video shared on Weibo shows that the phone with the discoloration rear case of the electrochromic glass is Vivo. Changing the color on that device is done by pressing a button. Also, in this video, the top of the camera slot is covered.
