When I transfer the files from old device to my new Galaxy Note3, the Divx / AC3 format files is not played in Galaxy Note3. What’s the problem?
Sorry for your inconvenience.
But your Galaxy Note3 doesn’t support the Divx and AC3 format file, and it’s normal concept.
Please download and use available player which is enable to play Divx / AC3 files from Google PlayStore or Samsung Apps.
