I've been working with my wife's phone and it requires 19gb out it of our 20gb plan. I ended up pulling off a few videos sizing around 7gb in size and the photos now reflect the 7gb drop. The problem is, backup does not, and after the automatic update, increased a little in size. Can someone explain why this is working this way. I'm assuming wiping and doing a new backup will solve this problem, but I'm curious as to why he backup won't decrease in size.
