Re: 0.00b available internal storage
First, is it a memory problem? What happens when you try to install an app or copy a file to the phone (they're not the same thing)? We need the actual wording of any error messages you get. The make and model of your phone would help us to help you better. It would also help us if you looked at Settings/General/Storage and told us how much free storage you have (bottom of the Device Memory list).
