Microsoft said today it has determined what is causing some Windows Phone
8 devices to spontaneously reboot and said it plans to issue a fix next
month.
"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."
However, the company declined to identify the cause of the reboots. http://news.cnet.com/8301-10805_3-57555282-75/microsoft-plans-to-fix-rebooting-windows-phones-next-month/
