I bought a 64gb sd card from Bestbuy. I inserted in my phone and hit format and it showed 58gb. But when I put it into my computer it would only read the card if I formatted it in fats32. I did that, but it only gives me 26.5gb's. The card works fine in my S5 that way. But I obviously want the full 64gb. So I reformatted it again in my phone. This time, when I inserted it into my pc, it didn't make me format to fat32. I thought great, i'm good to go. I download my old card on to the new 64gb card and it works fine in my computer. But when I insert it into my S5 it freezes, doesn't recognize it. A solution would be much appreciated. I did read online that you need a third party pc app that can format 64gb, but the one I tried didn't open for me.
