Screen still goes dead.

Anyone find an actual fix to this?

Info 2

I had pretty much the same problems with my Galaxy Nexus running CyanogenMod 11 M12.

It got better by doing the following :
  • Blowing dry air in the earpiece… though the proximity sensor is clearly beside it. Can't do any harm though, I guess.
  • Settings/Applications/All/menu/Reset applications preferences (or whatever that's called in english) : that seemed to do a lot of good to my phone ! However, it's a very unsatisfactory answer on a technical point of view, as I still don't know WHAT was precisely needed. It's a "magic wand" solution for which I can't give an explanation.
  • Not specifically related, but greatly helped my phone in the responsiveness area : Trimmer (fstrim) (, an updated version of LagFix that you may already know

Hope that helped !

(I wanted to try as well, but apparently, /sys/class/sensors/proximity_sensor/prox_cal does not exist on my phone…)
