What's the perfect internal storage preserving technique? Does link2sd and data2sd interfere?
If you are using the Pro Version of Link2SD, then you will be able to move everything of the APP(Apk,Dex,Lib,Data and Cache) onto the second partition of the SD card.And thus you won't be using any internal memory. My Phone has 157mb internal memory and I have apps that would have allredy filled it installed on my phone without losing space.
