There has been lot of talk about a glitch in the Windows Phone 7 operating system. However, Microsoft has pinpointed a third-party software developer for unusually high data charges for few users.
The unnamed third-party software is believed to affect only a small fraction of users. It caused the devices running on Windows Phone 7 to transmit “phantom data” unknowing of users which increased the data usage. The users were then left with hefty data bills. The seriousness of the flaw can be judged from the fact that in some cases usage hit upper bandwidth cap on network.
A poster named Julie G writes on Paul Thurrott’s Supersite for Windows that she got a notice from her carrier, AT&T, that she was about to exceed her monthly data limit of 2GB. Among the unusual activity on Julie’s phone was on December 23 when she put the device on airplane mode to stop the data stream. “I turned airplane mode off briefly on December 23rd and the phone sent 400 MB of data,” she noted.
A Microsoft spokesman said: “”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.”
Microsoft may fix the problem without actually releasing a fix for system software update.
