I have bought a 3 meter charging cable from ebay, but my sister said that those were bad for your phone, and I thought that every cable has the same purpose: sending signals. So can someone tell me if they are bad for your phone. I don't know if this matters but I have an samsung galaxy s3.
Btw here is the ebay link http://www.ebay.com/itm/281310056608?var=580350457121&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
