Serious issue with sudden turnoffs
I've noticed that my device has suddenly turned off on several occasions; I only notice because it does not respond to the power button and to use it I must take out and reinsert the battery.
I am running the latest installer build. Is this an issue with CM, the phone or something else? I need it fixed quickly because I am missing important text messages and phone calls. Should I flash M9 over the installer build, or is it something serious enough to merit a deeper change?
