Android Insufficient Storage Available error and Solution

Even on the new android smartphones presents the following problem  that there are insufficient SD Storage available to move the applications from the internal memory to SD memory card. Also the same problem comes up when someone try to download an android app from Google play store.In both cases comes apps the error message about insufficient memory even though there is plenty of gigabytes free capacity in SD
 
when these error messages appeared tried to delete all the data from my external SD Card, then I made a format then I selected the preferable storage destination to be the SD card and I also tried to disable the antivirus program.

From the actions above I succeed the in doing nothing..

Many say that you have to make a factory reboot with the SD  card emptied and inserted  in the android phone while you do the factory reboot. Then of course you have to install all the applications from the beginning.
