I have a Galaxy S3 AT&T phone which is supposed to support playing of wma and wmv files. I cannot figure out how to play wma files. I download audio book files from various libraries using Overdrive Media. Overdrive Media has an app for the Galaxy s3 which I have loaded onto the phone. Overdrive downloads files from the library and then I transfer them to my phone. The files are listed on my phone, they are wma files and I assume not protected since they are designed to be played so the book may be listened to. That's the way it is supposed to work. If I connect the phone to my computer, open windows explorer and find and click on the files they play on the computer, but they won't play using Music Player or Google Play on the phone. I get a message saying the format is not supported.
