This month, some users of Windows Phone 8 devices began reporting problem of spontaneous reboots and problems syncing their emails with other accounts and devices, CNET reported Tuesday.
"We're continuing to investigate some reports of phones rebooting and have identified a cause with our partners," Microsoft said in a statement.
"We are working to get an over-the-air update out in December," the software giant said, although it declined to identify the cause of the reboots.
Windows Phone 8 devices were apparently the only ones suffering the problems. Windows Phone 7 handsets were not experiencing the issues, CNET said.
