In the early days when USB Type-C was not prevalent, micro HDMI started to be used with some smartphones like the Motorola Droid X
Micro HDMI being a new technology, Motorola used this as its top advertising features
GoPro cameras were also using micro HDMI for some time and Apple using this for its Thunderbolt
But with time as USB Type-C became more popular and the standard for phones, micro HDMI was ditched by everyone.
