Had bought the battery from SlashTec GmbH (no recommendation). When he arrived he was not in a Samsung-packaging, but in a plastic bag. Had I actually have to do already suspicious, but I wanted to give the whole a chance because the battery from the packaging and labeled inferior to the original in every way. So pure battery, mobile phone. As far as everything OK. Battery ran without problems. But after a few days, the NFC has struck me, not working at all. For testing the old original battery again reingemacht, NFC goes. Thus, in the new (alleged) "original" battery pack is apparently no NFC, although even it says on the battery itself!
