My Lumia 710 reboot by itself, often
My Lumia 710 start reboot random after upgrade tango by Zune. I always use the core ROM, only update by Zune.
So, I read a forum that a fellow disabled the option to "my location" in settings, and the phone stop reboot. This fellow have a HTC with Tango, but I tried do the same on my Lumia 710.
Nice result... 2 days with no reboots. Seems work for me.
I configure all languages the same (keyboard input, search and SO) at same time.
Maybe this help to.
I hope help you guys.
Best regards.
