you might try out transaction of files via another pd or might try out with another otg cable for the same
there is a possibility of these two things being faulty or incompatible with one another
if the problem still persists then there is slight change with your read/write permissions to the folders/files
might try out the above and let me know
hit thanks if i solved your query
just a bit confused here.
are you copying files from your pd (pen drive) to your phone via a otg(on the go) cable. or are you interpreting the data transaction with a pc.
also would like to know if your phone is rooted and are running a rom /kernel?
happy to help
