I have a problem of huge storage space missing in my newly bought Galaxy Tab 2 tablet.
It is the 16 GB version, but even after resetting twice to factory settings, the available storage space remains at about 5 GB, with the remaining 11 GB inaccessible, because it is "used for Android system files".
I suspect that there may be back-up or batch files from the previous installations that Android does not remove when I restore to factory settings.
Does anybody know in which directories I should look, and how I can delete the relevant folders to free the expected 6-7 GB of remaining storage space that I need for my applications?
