1. The easiest way to play the audiobook is to use an audiobook app. We recommend the free Smart Audiobook Player app in the Google Play store. You may be asked to upgrade to the paid version but the free version will work fine.
2. Once an audiobook player has been downloaded to your phone, allow app to access the media files on your device. If prompted to set up the root folder, select OK and choose the Download folder. If prompted to allow m4b files, select OK. When the app scans for the file, it should show up in your Library. If it does not show up after the initial scan, refresh the library again to look for the m4b file.
3. If you are unable to play the file from within the app, you can also try to play the audiobook file directly from your downloads.
