We know that upcoming Moto Z will support a different type of accessories called “Moto Mods”. After seeing some of the Moto Mods, this time, new accessories called “Style Mods” have leaked.
“Style Mods” are back covers that allow you to customize your Moto Z. However, unlike the regular cases, these style mods are attached to your phone via the smart connectors on the back of the Moto Z and maybe with some magnets.
