Link2SD Plus is an awesome app for transferring your apps into SD card. It helps you to get more space to store more data into your device storage. You also get more speed as your device doesn’t have that must data so it keep speed on standby mode.
Link2SD Plus App take minimum permission from the administrator to run on your device, they all are basic permissions which any app takes. Also, this app has some requirements to run on your device which you can find here.
Link2SD uses a secondary partition on your SD card and uses it as another segment of internal storage.
Link2SD moves apk, dalvik-cache (.dex), lib and internal data files into this partition, which the OS mounts on boot, and creates a symbolic link in the original location.
This retains the file structure that the system expects but with the bulk of the data moved to the SD card.
Linking obb and external data folders of apps and games
On devices that have emulated SD card, obb and external data folders are located in the internal storage, not in the external (real) SD card.
Link2SD moves these folders to the 1st or the 2nd partition of your external SD card (depending on your selection) and with the bind option of the mount command remounts the file hierarchy at external SD card while it is still available at the original location.
