Get rid of CRT screen off animation in 4.2
For some reason the CRT animation always has felt slow as sin, so I usually keep it off. Changing animation settings in developer options no longer works for some reason.
Put debug.sf.electron_frames=1 in either local.prop or build.prop.
echo "debug.sf.electron_frames=1" > local.prop
Remove this to re-enable. Default is 24 frames.
Root required to do this. This assumes that you have no local.prop. If you do, you probably don't need this guide.
1) Get into adb shell
3) cd /data/
4) echo "debug.sf.electron_frames=1" > local.prop
