If I go into the Storage option under settings I see that my internal storage has 577mb free with 1.7gb in use. If I go into apps and show all (vs downloaded) after a minute or so the total down the bottom, which started out matching the other numbers, changes to 870mb free and 1.4gb used. Any clue how that discrepancy happens? I keep getting low space warnings about the 577mb free and trying to figure out what's up because when I add up my app usage, it is nowhere near 1.7gb. Thoughts?
