The back is amazing but there are some elements not quite sure the functions, apart from the cameras, the dot matrix and the touch button for the dot matrix interaction. Some of them looks like buttons, a slide or looks like for a purpose. Anybody can help to explain a bit more in details?
Update: looks like I will be disappointed. I saw some tear down video about phone 3a and those fancy thing on the back are just decorations.
I would rather remove them and just expose anything inside.
