I run the adapter to a Samsung Galaxy S4. At first I had a few problems. One must know the following (refer to my S4, possibly also on other models): - For the HDMI connection between the small adapter is needed and the power supply must be connected. - For connection to a disk must be used the intermediate adapter is not, and also connect no power supply. - For the HDMI button may have to be pressed until it is red, the BLUE disk (which is at least in the instructions). - The adapter can (of course) always use only one function at the same time.
If you do it all correctly, it works flawlessly and makes the smartphone an even more useful and flexible companion. Other compounds, such as external keyboards, external hard drives, etc. should also work, but I have not tested yourself. This is not the English manual of blockbuster, can get over it, especially XCSOURCE reacts very helpful and accommodating with questions and problems. Not least so full 5 stars!
