This controller is WITHOUT AN APPROPRIATE China app not to run TO BRING! Have IT skills and the key combination for PW on Smartphone without key assignment does not crack. This app has all the time running in the background so that the controller with my HTC M8 remains connected while producing advertising without end and of course offers a lot of Chinese games for purchase ..! In addition a miserable Chinese / English instructions. HAVE THE CONTROLLER ONLY IN ONE GAME FROM run to get, and non that of any emulator So do not touch !!!
