General - Storage Usage help - numbers don't add up
I am confused how the numbers are adding up for my storage. Maybe someone here has some ideas.
I am viewing Settings - General - Usage to find out my storage.
It says I have 11.9 GB used. However, I manually added up all the GB and MB for my apps and it comes to 7.6 GB of storage being used (yes I 'showed all apps'). What's up with this? Why is my Ipad showing I'm using more than 4 Gbs that I actually am?
I have a 16 GB Ipad 2. The ipad says I have 11.9 GB used, and 1.9 GB available. This gives me a grand total of 13.8 GB. Where did that other 2.2 GB go (to make 16 GB)?
Thanks for you help,
