Anyone found a solution to this issues? If manually lock my screen with the power button sometimes the phone will shut off. Not when I lock it but shortly after. If I let the OS screen timeout lock and never has this issue. Sadly I've gotten in the habit of never manually locking to make sure my phone stays on and this take a bit of a hit on the battery. It's not critical just annoying. I've seen similar issues like this reported but they were checking out the battery and other things and it seems to be completely software related. I'm sure it will be cleared up when CM9 is released and I updated. I'm just running stock OS right now.
