Microsoft have now completed their investigation into Windows Phones that have been leaking data. It was first reported at the beginning of January that some handsets were transmitting between 30 and 50Mb of data every day. This was even happening when the phones weren't being used at night.
Most complaints about the data leaks were form the US and Microsoft said it was affecting on a "low-single digit" percentage of customers.
Now the company has completed its investigation into the leak and has reported that it's a "third party" service that's responsible.
Microsoft are refusing to name the culprit, though they are saying that "We are in contact with the third party to assist them in making the necessary fixes." and that in the interim they were looking at "potential workarounds" to the problem. One workaround for instance could involve the developer of said app coming clean and users uninstalling it until a new, bug-free, version can be released. This could cause a company tremendous harm however in the long term which is what Microsoft are clearly trying to avoid.
It's still also possible at this stage that the offending app has been written and deployed either by a carrier, AT&T have been mentioned, or by a handset manufacturer.
At this stage though it's anybodys guess and its unlikely that Microsoft will ever spill the beans. A software update for the offending software will appear and it's possible that only if its a carrier's fault will we find out. They would do this to make sure that none of their customers are billed for the excess usage.
Either way it's good to know the fault has been found and better to know that it's not a serious flaw with the operating system itself. We'll keep you updated if and when further news about this is released.
