Not sure if anyone has run into or dealt with this issue, but I have Moto X with AT&T that is mostly connected to our Home Wi-Fi. My understanding of Android based smartphone is that when connected to Wi-Fi it is not supposed to use your data. Even those at AT&T verified that this is supposed to be true. There is never any video used or anything like that when not connected to Wi-Fi; so I have not idea why it is sucking 1.6gb of data in 3 weeks. Any insight on this would be greatly appreciated... Thanks
PS I had a galaxy s3 before this with the same issue.
