Link2SD

Even if many devices that are being launched today have one massive storage volume and no support for SD cards, there are still a lot of phones and tablets out there that do have this kind of functionality. If you don’t want to crowd the main storage of the device, you might consider using Link2SD.
 
There is a catch though. Because Link2SD uses a secondary partition on the SD card, it needs ROOT access. Most your apps can be moved to another location, and symbolic links are created. As far as the operating system is concerned, nothing has changed.
 
It’s also possible to forcibly move an application to the SD card, even if it’s not supported, to set the default installation location of an app, to check the available space on the card, and even to clear the system cache.
