I have a Galaxy J3 V, running Android 6.0.1. I have an external micro-SD card (32 GB). I THOUGHT I understood the difference between the "fake" SD card (actually a part of internal memory) and the "actual" SD card (the actual card). I've moved a bunch of music and photos to the actual card. I THOUGHT I'd moved a bunch of applications to the actual SD card, and the Android Application Manager shows that they're using external storage. But now when I try to move more apps to the actual card, I get an "insufficient storage space available" error. Same thing happens if I try to download new apps (which I'm doing because i just got an Android watch). There's definitely space on the actual SD card -- about 15 GB left. Any thoughts? Thanks.
