Symptoms: Within 5 or so minutes of watching videos stored on memory, the first symptom is that I can not stop the video or view progress, etc. If I touch the screen, the video just continues. The phone will not respond to touching home/back/power buttons, either. Then, after a couple of minutes of this, the screen stays lit, but blank, for about 10 seconds, and then the phone reboots. This is not limited to any one video style. I've also tried it having the bluetooth streaming for audio and with just earbuds installed. Though I had not installed any new apps recently, per suggestions on other forums, I removed Pandora to no avail. I tried battery pulls, wiped the cache, updating "roaming capabilities", and task killer. I've also had two instances recently where the phone freezes within 5 minutes of booting and the only way to resolve it is to just leave the phone alone for an hour or so. There was a system update a couple of weeks ago, and I'm wondering if this is the culprit. Suggestions?
