I'm as familiar with an SD card in Android phone as probably most people are or at least common people. But this issue is driving me crazy and it began today. The files on my SD card are accessible I'm able to delete and move files from one folder to another on the SD card but I cannot move files from internal storage to the SD card at all. I'm getting the message cancelled. I think it may be a setting because I was playing around with the phone today and using third-party apps. Can someone please help me and please don't recommend formatting the card because I really would rather not invest that much time since it's almost two hundred gigs. Thank you.
