Microsoft is looking into a puzzling issue with Windows Phone 7 whereby the operating system appears to be sending mysterious chunks of "phantom" data.
Some WP7 users who hardly use their 3G connections have been reporting that their monthly data usage is being eaten into by their handset sending this phantom data. Some of these folks say small chunks of data are being used up, and others larger amounts.
One member of the Microsoft Answers Windows Phone 7 forum noted: "My data usage has skyrocketed since getting a Samsung Focus.. There is something wrong with these phones. I have large data usage occurring after midnight on most days on my phone. I have wi-fi enabled and I am at home. Is anyone else experiencing high data usage?"
Other forum members think that this may be an issue with the setting that allows the handset to send feedback to Microsoft, and that this should be turned off. Another poster also recommended turning off searching for updates, and said that taking these two actions cured his problem.
A BBC report also mentioned that it could be the fact that the phone is using a 3G connection even when a wi-fi one is available.
Another WP7 handset owner on Winsupersite.com was quoted by the Beeb as saying: "I received an e-mail from AT&T saying that I was close to my 2GB data limit which truly shocked me as I feel I do not use data that much."
"I went and looked at my AT&T account online and noticed that my phone was sending huge chunks of data seemingly in patterns."
Microsoft said it is now investigating this issue to determine the exact cause, with more information due as and when they discover it.
