I'm running a custom MM ROM on my SM-T320. Everything is smooth and stable except when I insert a micro SD card. I know the pros and cons of "format for internal storage". That's not my issue. I know that you can have the T320 reformat a micro SD card to make it readable external storage. That's not my issue either. I can't figure out why, when I insert a working micro SD card with readable music and video files on it, the music and video apps on my device can't see those files. I know that the DEVICE sees the files. When I pull down the notice in the system tab about whether to "format or explore", if I select Explore, the utility sees every file on the drive and can play every one perfectly. So, why won't my media apps see those files?
If all I wanted to do was to plug that micro SD card in the T320 and leave it there for storage I'd have the device reformat it and be done with it. That's not what I want. Before this, I could have different micro SD cards with different selections of media and other files and plug those cards into whatever device I wanted to use to read the files. All of the devices would recognize and read all the micro SD cards. With Marshmallow that seems no longer to be true. Am I doing something wrong or is there a work-around?
