Afternoon all - Long time visitor first time poster... I have a Galaxy S2 and use the Data Counter widget from the Market. I used this on my old HTC Tattoo and always found it was pretty accurate. Now on my GS2 it seems that it's missed about 100mb of data use. When I spoke to Vodafone (and checked on the My Vodafone app) they say I've used 400mb as opposed to the Data Counter saying about 300mb (it's a new phone hence the massive usage anyway - this would not be a normal month!). My question is - Could things like Backgrounds Syncing or Ads in Games be to blame for this? And if so how do I get rid? Anyone else had a similar problem?
