Android and more specifically Google has yet to offer an install to SD Card feature. Since this is an OS limitation you may have to re-think all this.

Once in a while you encounter some one new to Android devices and lash out about this area but what can you do but uninstall what you can to run what you can and then look around for a move to SD option. That option did vanish for a time and Samsung had nothing to do about that. Google controls this OS and most of the polish you see is in the apps the device maker provides.

Hope you can wrap your head around this.
