A:AnswerIt will if the phone/tablet is OTG compatible. I use it with my Spark and a Verizon Ellipsis 8 tablet. It also works with my Moto Z using a USB-C adapter.
A:AnswerSamsung and others used to make a HDMI cable, but I'm not sure if it's still available. A better choice would be a Chromecast device then cast from the phone to the TV.

A:AnswerNo. This is USB, not HDMI. Can you use it with a USB to HDMI adapter? It depends on the make, model and specs of the other adapter. This OTG adapter works as advertised.
