Hi! I've got a htc one A9. I used the otg many times in day, with flash memory or a memory card in a reader and then put in otg. After so many times that I use; someday it didn't works for memory card! In flash memory it's ok just like past but memory card didn't works. I do anything to fix this like: reset factory, formating the card in computer and phone, changeing the otg and memory card reader, trying diffrent memory; but nothing changes! Flash doing great and memory not working!
Please tell me how to fix this.
