I can't use my usb even after getting developer options on. Not yet inserted sim in my new "Samsung Galaxy Grand Prime 4G"(model - SM-G531F) want reverse tethering for using PC internet in mobile. Although I have developer options on still PC is showing usb device not recognized. I don't have wifi any tips?
