Ever noticed what data sense does?

[Athanville]

Most of us have updated our lovely Lumias to Amber and above, so we know what Data sense is, the app works fine until you set your data to unlimited, it will count up to 2GB data then start counting back down and mark you mobile data hasnt moved, like mine for the last 2 months mobile data has been at 16mb and my WiFi data at about 2Gb but its counting down then back up, anyone else have this issue?

Also dont you think transfer my data would be nicer if you could send data to another phone and create a local backup? sometimes cloud may not always cut it.
