Samsung Micro-USB-to-HDMI adapter (eleven-pin) The Samsung Galaxy S III, and later Galaxy Note II and Galaxy S4, use an adapter and Micro-USB socket with six additional connector pins in order to achieve functional improvements over the 5-pin design: It supports the use of USB and MHL simultaneously. (Note that the new Samsung 11-pin MHL-HDMI adapter also has a USB On-The-Go port).
