As many speakers also I got a probably fake charger sent. After 3 times charging my Samsung Galaxy S2 was a surge and was consequently no longer fully operational, which is why I had to send it in for repair. The defect was confirmed by the repair services. Since the charger quickly became very hot and the charging process lasted longer than before, it seems likely that it is a forgery at the order unit. Pity! But in retrospect, I have to take at themselves. A device that is reduced from 17 to 4, may be no original commodity itself. Well that does not happen in any case again. Still hope that Amazon manages to avoid such Vorkomnisse in future!
