Re: why i cant move my apps in sd card in lolipop version
Only apps that the developer allows to be moved can be moved. (Some libraries used in apps can't run from the SD card, so that app can't be moved.)
If an app can be moved, only small pieces of it are moved - at best links to those pieces are all that's left in internal storage, but Android looks for apps in internal storage (on the device named sd0, which is normally internal storage), so the entire app can't be moved or Android will never find it. (At worst, so many small pieces are moved that the total size of the links is larger than the size of the app, and you lose internal space by moving the app.)
