Issue with Proximity Sensor during calls

I'm having an issue with the Proximity Sensor not properly detecting when i'm holding my phone to my ear. I can confirm that the iPhone sensor is working by covering it with my finger, but when held to my face, the screen blinks as if it cannot decide to disable the screen or enable it. It results on me hanging up, putting calls on mute, and dialing numbers accidentally while i'm on the phone. This occurs on 90% of my calls. Is anyone else experiencing this issue. I would like to confirm whether this is a software issue (Proximity Sensor sensitivity too low) or a design issue (sensor now placed towards the end of the phone).

Macbook Pro, Mac OS X (10.6.4)

I am having the exact same issue where my face is ending the call, muting etc. The phone is not usable for me. Trying to get my old sim reactivated now and reverting to the 3GS.

I was having this problem, but I reset the settings like mentioned in this thread and it works just fine now

Resetting all my settings did not work for me. I am still having random dial, hang up, etc issues.

Same here. I reset all my settings and am still having the problem. My phone has a slight manufacturing defect too, there's a piece of rough plastic protruding from between the bezel and front glass. I'll be going to the Apple store for a replacement when things calm down, and hoping it solves the proximity issue.

If not, I'll be downgrading to the 3GS. While this phone is amazing for it's speed and looks, if it can't make a call without me hanging up on people or tossing them on speaker randomly, or entering numeric codes in their ear, it's useless.

Count me in for having the same problem. I did the "reset all settings" thing and I'm still having major issues. I hung up on someone 5 times, accidentally muted calls, tried to start a face time chat... This doesn't feel like something I can fix on my end... anyone else have a solution?

Same problem here. I just spent an hour on the phone, and muted or had some other issue five or six times. I reset the phone, but the problem persists. I hope Apple comes up with a fix soon!

I'm having this issue as well. I had no problem at all with my 3G but on the iphone 4 I keep hitting buttons with the phone against my ear.

I have the same troubles, in addition, when the phone is in bluetooth mode with my cars system, it will switch between the handset, the speaker and bluetooth.

Having the exact same issue. This is making phone calls very difficult. I'm hoping this is a software issue and not a hardware issue.

Yeah, same issue here. I thought I was going nuts because I was on the phone with my sister and somehow navigated to settings/ring tones and started hearing crazy stuff while talking to her. Never ever had this problem with my 3GS. Regretting being an early adopter right about now...

I'm also having this issue. It appears that the phone is too quick to assume I have pulled the phone away from my ear when it really has only barely, and accidentally, broken contact. One would believe this is relatively simple fix to make when 4.0.1 is released.

Yeah, I'm having this same problem. Unfortunately, the only remedy I see for the problem is to hold the phone differently, so that the sensor stays on your ear. Maybe they can release a software update to desensitize it a little, but I don't think that's there main concern at this point.
