i just bought a 16gb pny class 4 micro sd card and my htc one sv wont detect the card when I insert it, just nothing happens its like it doesn't know theres a sd card in it, but when I put it in my brothers windows phone it work also along with my old android, I got this phone from my step dad so I don't know if the micro sd card port is broken and needs replaced (if you can even do that).so if anybody has any suggestions for what to do to help fix this it would be greatly appreciated. any help?
