Proximity sensor problem - Galaxy S I9000 Q&A, Help & Troubleshooting

During a call, the screen randomly turns on and so the call gets notoriously disconnected because End Call button is getting pressed with a cheek or hair or whatever.
Is there some way to either fix it, or just disable it so the screen remains off during a call, unless Home button is pressed?
I tried several roms and it's always the same.

Power Button

is teds tools or noled the only kinda sorta way around pressing the power button to turn the screen on while talking on your phone after it goes dark? i press my power button while on the phone during a call and it drops the call.
you should just have to pull the phone away from your face, or turn it flat while on a call to turn the screen on.
The captivate has a proximity sensor that has the screen turn on when it pulls away from your face. If the screen is not turning on, there could be a problem with the sensor.
how about when using a bluetooth headset or headphones? i just called myself and set the cell phone down until it went dark, picked it up and not even teds would pop back up so i pushed the power button and it cut me off again.

WTH is teds???
guess it was a bug with the cognition rom. i started getting process errors during phone calls when i dialed out. removed the rom, reset to factory and the problems are gone. i can now push the power button to light the screen up during a call without it cutting the call. but im still planning on taking it back to trade it for an atrix

Cant unlock while incoming call

Since i installed CM9 nightly, occasionally i cant swipe pickup/unlock while incoming call.
Screen lights up, all the icons are there, but frozen until incoming call ends...
Phone has been wiped multiple times after CM9 upgrade...
Any ideas what's happening ?
yup its known bug and for me locking and then unlocking screen at the moment of incoming call does the trick
Screen off and on does the trick
yes pressing the power button which turns the screen off, then turning it back on makes the button respond again.
Good luck

Proximity Sensor Error?

Whenever I make or receive a call, the screen shows the "incoming" or "outgoing" screen for a second, then the screen turns off.
Upon turning it back on, it turns back off after about half a second and won't turn back on, I tried pressing power and home button, putting my finger over the non-physical buttons at the bottom and applying pressure along the edge of the phone.
This is a major flaw since when I'm making a call and they don't pick up, it stays on the "please leave a message" portion of the call and I am forced to shut the phone off just to continue using it. The same happens when I get an incoming call. The accept and reject buttons don't appear so I have to wait until it rings to call them back. What is the point of I can't simply make calls on a smartphone?
I have already disabled the proximity sensor via the call settings, but it didn't make any difference.
This is very frustrating when I have to make many calls.

Do you have a case on it? The case might be blocking the sensor.. Also, sometimes an app causes problems with the sensor.

No screen off during phone calls

I could swear their used to be a setting in the phone app to automatically turn off the screen during calls. I can't find it in the version with this device, and although the proximity sensor works when I'm holding it to my ear during a call, when it's in my pocket the screen stays on, (or if receiving a call/connecting while driving it turns on), leading to the mute, bluetooth, or end call buttons being randomly pressed during calls and causing issues. Am I just not finding the setting, or is it gone, or is there some other way to shut off the screen automatically when a call is connected? ( I know, don't leave the phone in my pocket by driving, but looking for something a little more functional here). Thanks!

How to leave on screen during phone call so I can control buttons?

When I'm on a phone call the screen turns off. This messes me up if I have the mute button or speaker phone (accidentally) enabled. When the other party picks up or asks something I'm unable to get the screen back quick enough and they assume the line dropped. This is really annoying. I use the power button on the phone to hang up so pressing it wouldn't work. How can I fix this problem? The easiest way I can think of is if there's an option to just not have the screen turn off?
When this happens I try tapping on the screen but it usually just comes back momentarily before I can unmute.
