Help SF screen goes black when calling...

HI, I am using Modaco r12 version... and I have a problem when I try to make a call... as soon as I stick the phone to my ear... the screen goes black and I can not do anything i.e. disconnect the call... I have to wait until call is finished and someone disconnect himself... then screen comes back. Factory reset did not help. Does anyone know how to fix this? Or maybe three is better ROM to install that r12??
 
my best guess is you have an issue with your proximity sensor. It may be the rom (i have no experience with r12). you may want to flash a different rom or go back to stock and see if the proximity sensor works then. If not i would bring it back to the store and see what they have to say

I have tried different ROM... still had the same problem, well it was even worst... so I started reading about proximity sensor as you suggested and I found:

Proximity sensor - sf screen goes off when calling:
Go into the Dialer an press *983*0#
Go all the way down to Sensors.
Hit"testing light" and then hit "testing proximity".

I give it a try... plus I did calibrate (additional option next to testing)... then a message 'proximity sensor OK' appeared just for a while and it works now!... although this soft still is saying proximity sensor fail on this page. I hope this will help someone who has experienced similar issue, too.
Cheers,
 
Wife's got the san francisco phone and The screen timeout is set very low like 30 seconds etc and thats still kicking in when on a phone call.

so screen goes off until you press power button again
 
Yea, as said above. It does it to me as well, when you want to hangup, press the home key, or the power key and it should come back to life :P
 
i've had this same problem since rooting and installing CyanogenMod 7. I didn't notice it at first, maybe because I don't really make that many calls, but when I did need to it quickly became annoying. I had to pull the battery at the end of every call.

I've tried various different Cyanogen ROMs, with the most recent nightly (CM7 Build #120) running at the moment and I still experience this.

Is this something that will be fixed in Cyanogen 7.1?

Cheers,

Ian
 
I've tried CyanogenMod 7 nighlies 105, 113 and currently 104 (pre-battery drain nightly). I've not had issues with my proximity sensor (yet).
