I understand that you still want to change its sensitivity. However, from what you're describing it's more like an interference case than the sensitivity issue. I'd send it back for repair if it's still under warranty if I were you.
Good luck.
Good luck.

The way the proximity sensor works is that it emits ifrared light, which bounces off something nearby (like a face) and is detected by the other side of the sensor (that's why there is a dividing line down the middle).
Unfortunately, sunlight also contains infrared light, which is why it is triggering the sensor. Same thing with a lamp. This is an inherent flaw in any infrared proximity sensor, and not a software or hardware problem. Replacing it will probably not fix anything.

I do have a screen protector but it has a cutout so the proximity sensor isn't covered.

Anyway, a screen protector does not necessary inhabit the sensibility. I read from other forum that an anti-glare protector would actually help in some cases.
I didn't recommend this as a solution as I don't have a proof on that claim. I just want to say you may not need to punch a hole on the screen protector to improve sensor effectiveness.

It can do, but yeah, may not necessarily do so, and Nokia say the sensor shouldn't be covered by a screen protector, besides my protector came with that part already cut out and the reason I mentioned it was in case anyone thought it affected my results.

@9000 - I would send it back for repair but I don't have warranty . Anyway , I'm using unlock button when someone calls me or end a call . Thanks for your help 9000 .

Done , I fixed it myself , I put a little piece of diskette tape on a half of sensor , now it works fine .

That is a very interesting hack. You are genius.
