Not all of USB3.0 Type C android phone are all real USB3.0
eg: SONY XA1 is just USB2.0 type C
Some USB3.0 Type C android is real USB3.0 mode
eg:samsung S8, Note8, LG G5, G6, V20, V30, and Pixcel2 we tested.
The real USB3.0 mode can use device and charge at the same time
If your "real USB3.0 " android phone connect USB3.0 HDMI capture card, it maybe not work
it is USB3.0 compatible issue!!!
How to let USB3.0 hdmi capture card work on "USB3.0 mode " android phone?
1. Connect TYPE C OTG line
you need "add " usb 2.0 line
if not, the video will be error!!!
you need add the "usb2.0 extend line" to become USB2.0 mode
