Help Samsung Galaxy S keeps dialing while I am on a call

[ctatum500]

My Samsung Galaxy S dials random numbers the whole time I am talking on the phone. My sister has same phone and her screen turns black while she is on a call and then when she takes it down from her ear it gives her the screen again to end call etc. Mine constantley lights up and changes screens and dials in my callees ears. Very annoying. I am ready to smash this phone. Does anyone know why it would do this? Cellular South says the screen should go black during a call. This is my second phone in 5 weeks and both did this. The cell phone rep tried m y phone and it happened with her also but she had no clue why. Help if you can. Thanks

Bad proximity sensor? Maybe

Do you have a case on the Galaxy S? The case may obscure the proximity sensor, if it's not a well designed case.

I do have just a pink silicone cover on the phone. The same one my sister has on hers. You can see the sensor fine. I got a phone the day they were offered at my carrier and within a week took it back for this problem and also severe dropped calls. This 2nd new phone does the same thing and when i went back again... they were trying to figure out if this phone had a setting for sensitivity or something.. I REALLY want to love this phone but so far I absolutely hate it. Have not had a good conversation yet without someone saying what is all that dialing in my ear? UGH How do I tell if that sensor is bad? Thanks for replying.

If I were you, and just as a test, remove the pretty pink case and make a call to see what happens. It could be that what you are thinking is the proximity sensor is actually the front facing camera.

Hope this helps.

Dumb question but do you have a screen protector on?
Some screen protectors may cause proximity sensors to act weird.
If its not the pink casing or protector, then definitely sounds like a faulty proximity sensor.

Also if none of the above work, try a factory reset.
I have heard of these phones glitching on first boot and not enabling the PS
