MS says Windows Phone 7 ghost data an outsider bug
Microsoft responded on Wednesday to complaints that Windows Phone 7 devices were chewing up large amounts of normally undetected data. The company explained that at least one of the flaws was sparked by a "third-party solution" often reached from WP7 was triggering the larger downloads. It told the Post-Intelligencer that it was both helping the unnamed outside firm get the issue fixed and preparing workarounds "in case those are needed."
Only a "low single-digit" percentage of users were affected by the problem, Microsoft said. Despite having isolated one problem, it promised to check into other claims that didn't fit the pattern.
Stories have surfaced of WP7 phones, regardless of the manufacturer, downloading far more than other phones with no explanation. The flaw has led to some users running over bandwidth caps on AT&T and, in extreme situations, as much as 50GB per day. WP7 doesn't have multitasking beyond Microsoft's own apps and doesn't have the excuses of third-party background apps creating the flaw.
