The article was received pretty quickly (about one week) The article seems not new: there is tape around the USB socket, it is not very serious. But for the price, I will avoid to /. After trying to configure my smartphone by any means possible, it turns out that this cable, like other OTG cable, probably, not necessarily this one only, do not work with the Wiko GOA. My smartphone is not explicitly provided this functionality not being free either, he had to take the test. For cons, the cable works fine with HTC. Tested with a 4GB USB key.
