I don't mean to resurrect an old thread, but I felt compelled to answer this, since this issue bugged me for hours. I'll just leave it here in case anyone else stumbles on to this.
If you are able to move apps to the SD card in G3, android v.4.4 Kitkat, whether by default, or by applying the SD Fix ("media_rw"...), then doing so will only move certain files to your SD (the .apk, I think), but not inside the /external_SD/Android/data folder. The files will instead be moved to the /.android_secure folder, which is hidden and cannot be viewed using a file browser in Android, even with root (tried ES Explorer). You can view this folder if you insert the SD directly to your PC via a card slot. The files moved will have the .asec extension.
In order to move the actual files from the data or obb folder, and save space, one would have to use an app such as FolderMount, although I haven't tried this myself.
