So I see a ton of these very nice looking leather cases w/ the magnetic close tabs on them, I almost feel as if thats bad for the phone in some way but if that would be true why are there SOOOO many of them being sold and advertised? Am I safe to use one of these cases for my Galaxy S3?? I tried looking all over for a nice leather case with the old style snap button flap or something but they must not use those anymore, lol.
