Not sure if people are still dealing with this but I have the problem on galaxy S5. Has anyone noticed that even if the files move to the SDcard-android-data-(corresponding app) folder, they don't necessarily get deleted from the device storage-android-data-(corresponding app) folder. I experimented and simply erased the folders of the apps I knew I had moved. This cut the data stored on my device in half, seemingly without affecting the apps performance. Since then, I've noticed that each time the app updates, I have to repeat the process. Does anyone with android knowledge understand what's happening there? I read somewhere about android maintaining a link between the two folders, but haven't been able to find that post or anything similar since.
I would really like to try this before I get into changing crap thru emulater.... Autocorrect might get frisky with my luck

You just checked .folders for duplicates?
Thanks much!
