[Q] CM10 Phone's Screen Stays Black When Unlocked

[Slacker101]

So what happens every so often when I hit the unlock button is that my phone screen won't come on. Everything else works fine but the screen isn't on so obviously I can't see what's happening. Is this happening to anyone else or is this a possible hardware malfunction? It's been happening with several CM10 based roms over the last month and a half. It's gotten progressively more frequent.

Sounds like you're getting what they refer to as SOD. Its buggy software in CM10 that will hopefully be sorted out soon.

I agree, likely SOD. If your kernel allows control of CPU voltages, I would bump them up for the lower clock speeds. Seemed to help for me.

Which "unlock button" are you hitting. It's a common issue with the CM10 ROMs that if you hit the home button when the phone is locked and the screen is off that it doesn't bring the phone to life as it should. I have it happen all the time and just have to hit the home button several times or hit the power button to unlock it. I haven't tried seeing if the phone worked with the screen off like you mentioned I've always just tapped the home button till it lit up finally.

This drives me crazy and it has me considering using another ROM. Is it fair to call this "stable" release so if this keeps happening? Just food for thought.

Realize this post is over a year old but it helped me fix my issue. I used Benchmark and Tuning (available for free on play store) which allows you to choose a few types of governors one of which was on demand. hasn't black screened since. Thank you guys.
