Same thing happened to me using Waze with Evo 7.8 last week.Anyone else been having issues with the phone randomly turning off? I think it's been happening since I updated to 7.7, and has continued to happen on 7.8.
To be more clear, it's not exactly the phone powering off per se - it randomly will completely shut down, not even holding the power button turns it back on - and I've only been able to get out of this state by holding power + volume up to force a restart. I haven't noted any pattern to it or preceding events; the screen just freezes for a few seconds before going off and then I can only fix it by the aforementioned method. It has happened both when on youtube, instagram, and many times when the screen is already off (I just notice I can no longer open my phone and have to restart). Doesn't seem to be related to the battery either. Generally it's not a big problem, as it's only happened like max 3x/week, but the biggest problem is when it randomly turns off in the middle of the night, thus making it so any alarms I have set won't go off.
I can't entirely say it's the ROM fault as I also am rooted, but I never had this problem prior to updating to 7.7 so the timeline certainly coincides. Just wanted to hear if anyone has had similar issues. I haven't been able to make a log or bug report due to the unpredictable nature to it.
I haven't had this problem yet with version 7.9.
