hello everyone, i'm having a strange issue with the data usage app on ICS (4.0.3, 3 UK, stock rom, updated via Kies). As you can see, the little lines on the bar chart have vanished. Same on Wifi and Mobile data chart. Tried rebooting phone, formatting cache partition etc. No joy. I can't find an option anyway to completely clear the data usage monitor, is it even possible? I'm not too fussed about starting again, but the missing lines on the chart are a bit annoying. Any ideas?
