I always use about 10-11 GB of space in any phone that I have had. Even when I had a 32 GB I only used about 8 GB. So whats my problem? Why aren't I happy with the 16 GB. I don't know...I think I just liked the idea that there was a whole bunch of space just sitting there even though I won't use it. But at least I am sitting here with my 16 GB space grey So it doesn't make sense to have a 32 GB if you aren't going to use it right?
