PHONE FREEZING WITH SCREEN OFF, REQUIRES HARD REBOOT
I've got a Nexus 4 running CM12, currently on 2-28 nightly, though this issue was present on the 2-24 nightly as well. Also running the Xposed Lollipop Alpha, with App Settings, ChromePie, SwypeTweaks, and GoogleOfflineVoice modules loaded and enabled.
What appears to be happening is that, at random times, I'll go to turn on my phone and the screen won't turn on. No response, nothing. Holding the power button to turn it on doesn't seem to turn it on in the normal amount of time if it had just been powered down. Instead I have to hold the power button down for about ten seconds as if I'm doing a hard power-off during a crash, and then press power again to turn it on.
Checking the battery stats, I'm seeing that the battery is definitely still draining, though the system is not running (the gaps are times when the phone froze, stopped recording battery stats, but you can see that when it was turned on again the power was lower than before .... around 12:30 I tried again and the battery was drained, so I plugged it in).
Has anyone else seen a similar issue?
