Detailed Information:
<br /> 
<br />For this receiver to work, your cellphone should support UVC function (not just OTG) which is capable of streaming video like webcams, digital camcorders, transcoders, analog video converters and still-image cameras.
<br />Most Qualcomm CPUs support UVC function, while only a tiny number of high-end MTK CPU do, none of the iphone support UVC. A quick way to tell is to connect a USB web cam to your tablet/phone.
