Anyone know why a third party cert cable is working on a mini ipad and an iphone 5C but not working on a iphone 5s. All have iOS 8.1.3, and I know since iOS 7 the software detects uncert cables, but this is supposed to be certified and is not working on the iphone 5S. Also the iphone 5s works normal with an original apple cable and I dont get the "this accesory is not compatible bla bla bla" pop up when I plug the third party cable. What gives?
