iPad storage full
An elderly friend has been given an iPad - also elderlyh - which is showing 'storage full'. Having tried various ways to free space, I eventually did a total reset. Before setting up it showed 11Gb free. After doing the basic setup with the 'obligatoiry' apps there was juts 105Mb left! I added up all the apps under the m,anage storage section and it was less than 2Gb.... so where is the other 9Gb and why?
All suggestions welcome before I do a total reset and start again.
