My Icon suddenly powered off and restarted several times since latest update. My wife's Icon has done it once as well. Seem to happen when on web pages. Any one else having this problem.
I have the same issue on all of the OS versions I had on the device since launch. (WP 8.0, 8.1 DP, 8.1 DP update 1) I wonder if I should send it in? Sounds like an issue that can be worked out with a new firmware, I think at least...
