Hi folks, I,m currently using a galaxy S4 and have accumulated a few movies, so I decided to purchase a 64gb usb stick with the mini usb fitting on one side and a standard usb on the other.
After watching a movie I transfered it to the stick and noticed instead of a movie pic icon it changed to a purple icon with a play sign on it. Not all have done this but all the files are the same kind mp4's. I tried to watch it on the tv using the stick but it didn't work (the ones with the purple icon). I transfered it back to the phone and it still won't play even though it work beforehand. I noticed when plugging the stick in knox comes on asking for my password. Is knox interfering with the file? or is there an app that can help transfer it so I can plug it into the tv to watch.
I have done this many times with a standard usb stick via the pc I.E phone to pc then to stick and the movies work.
Any suggestions welcome.
Thanks
