A:AnswerThe charger is made for Samsung Galaxy 4 and newer. So if you product falls into these specifics it should work just fine. You could also check on Samsungs website to make sure your phone is comparable with the charger.
A:AnswerI got that message often, so often that I brought the charger back to the store. The idea of having a wireless charger is to be able to walk away from it while it's charger. I felt like I had to babysit this one, hence I returned it, with no problem at all, to Best Buy, in the return period. I don't really miss it. I'll just go back to my cord charger.
