Microsoft Corporation (NASDAQ:MSFT) has resolved an issue that they had with Windows Phone 7. The Windows Phone 7 devices were mysteriously uploading massive amounts of data over 3G. Microsoft was investigating claims that the operating system was sending up to 50GB of unidentified data per day by at least one account. This was even when the phone was connected to a WiFi network. This inflated the phone bills by users.
Below is a statement from Microsoft regarding the matter:
We have determined that a third-party solution commonly accessed from Windows Phones is configured in a manner that potentially causes larger than expected data downloads. We are in contact with the third party to assist them in making the necessary fixes, and are also pursuing potential workarounds to address the configuration issue in case those are needed. At this point in our investigation, we believe this is responsible for most of the reported incidents.
We are investigating additional potential root causes for the remainder of the reports.
A small (low single-digit) percentage of Windows Phone customers have reported being affected.
We are continuing to investigate this issue and will update with additional information and guidance as it becomes available.
