I bought in January 3 of these cables, because it was shown that it is original Samsung cable. The battery is charged so that, no problem. But the phone was not recognized by the PC. Two days I've been researching, reinstalled, trying forums and was already on the verge of passing the phone to be repaired. Until someone gave the tip, but the original Samsung to use cables of purchase - and it worked without problems. So rather buy the same a real "original", which saves time, money and hassle.
