For most Android based Samsung Phones, there is a special circuit used to detect various forms of accessories, including UART, and download modes (aka. JIGs) . The various modes are determined by a resistive load between ID_CON and GND. These are often controlled and described by a FSA9280A chip (or like it).
Also compatible with any Samsung phone that accept micro-usb coonector.
