link2sd not linking properly
Link2SD can't put the whole app to the ext partition. There's always a little part that takes the memory.

Use simple2ext. There you can select which folder to move to ext. After rebooting the whole dir will be placed at ext, and linked (mounted) to the internal memory. (mount has a mode when you write into the shared folder it will be mergred into the mounted folder) It seems like it's internal but not. :)
