A:AnswerHi, Jess.
This Adapter would not work with your Motorola Z3 since it requires a USB Type C connector. You can check out our model NS-PU369CH-WH.

A:AnswerHi Paula.
Doing research on my own I found that the Samsung S6 does NOT have a Micro-HDMI port built-in. My best suggestion for you would be a Micro-USB to HDMI adapter, or a Micro-USB to Micro-HDMI adapter and then use this one on top of it.

A:AnswerThis will absolutely NOT work. The connector on this cable is -micro HDMI-, NOT micro USB and NOT USB type C. This is not a cell phone connector, please ignore the response given by Insignia Support!
A:AnswerIt will not work. I am aware that the LG K20 has a mini USB port on the bottom of the phone, this adapter is for a micro HDMI port. They are made mainly for GoPro cameras.
