OK, I'm probably doing something wrong. I bought a brand new 32GB micro SD card for my Lumia 620 (last one turned out to be a counterfeit). I installed it, formatted it using the phone, transferred some music and movie files over to the music and video folders on the micro SD card. Lumia's built-in player cannot see those files. My computer sees them just fine, and was able to play them.
I downloaded Smart Player. It doesn't see anything on the micro SD card either. I tried Media Player. But it only plays streaming stuff from online sources.
Can someone recommend a media player that can see files on the micro SD card and play them?
