Brother, I found the solution, or good in my cell (LG Optimus L5) worked
A few days ago look truthful in applying Link2SD move a configuration for the installed applications on the SD or external memory (which is impossible in this cell and the L7)
Today I remembered, and turned to put configuration and internal memory, and it worked !!! Restart
Wait serve you and if not maybe your installed application Link2SD like to do the same
I'll help just tell me your device and help you
Luck and hope you work!!!!!
