Hi!

since a few weeks I have a problem concerning the display behaviour during and after calls. When I do a call (does not mind if I start it) and I activate the prox. sensor (e.g. when taking the phone to my ear) the display goes off as it should, but most of the time, when I take it back down, it doesn't turn on again. I read about some problems with uncalibrated prox. sensorsand some issues with CM Mod but all these threads finished with the problem beeing solved by a recent version of CM. Therefore I am not sure what to do now and so far, I didn't find a solution.
When this happens, I always try to switch it off to standby and back on... after several tries it usually works again until the next call.

So far, I tried to flash different roms... all of them more or less recent nightlies. Right now, I am using CM Nightly 258.

Would be very glad if someone can help!

Hi there. You may have the same issue that I have. My proximity sensors do not work. My screen goes off when I answer a call and it can be a nightmare to get it on again. Sometimes I had to pull the battery especially when checking my voicemail.

I work around it most of the time by going to settings>CyanogenMod settings>Input and ticking Trackball wake. If I make or answer a call I can usually get the screen to come on again if I press and hold the trackball for a couple of seconds.

There is a small app available for free from the market called "sensor test" . Get it and run it and it will show the outputs from your sensors.  

Mine shows
LIGHT
CM3602  Light sensor
0:10.0
1:0.0
2:0.0

PROXIMITY
CM3602 Proximity sensor
0:0.0
1:0.0
2:0.0

These values never change on mine which I think means they are not working. If the values change on yours when you cover or uncover the sensors then you have a different issue. Hope this helps.

Hi!

thanks for your answer!

the proximity sensor values change: from 0:0:0 (dark) to 9:0:0 (bright), but not in steps... just the two values.
the light sensor also works... values change significantly when I hold the device below a lamp e.g.

So your sensors are working, have you tried wiping the dalvic cache in recovery. Sometimes it will fix glitches and it will not break anything.

...no... wiping the Dalvik cache doesn't help

I have the same problem since I used s2e to move everything but /data to sd ext . Do you use the script to ?

Try to disable both Screen-on animation and Screen-off animation
Settings->CyanogenMod settings->Display

This works for me
