Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

During call, face is hitting Mute, End, Contacts, etc. buttons.

I had the iPhone 3G for two years. After dialing a call, one brings the phone to one's ear, the screen goes black BEFORE contact with one's face, and the call proceeds. I never had a problem with this in two years - not even a single time.

The iPhone 4 I got early yesterday is consistently allowing my face to mute calls, hang up on calls, hold calls, etc. before the screen goes black. Of course I don't realize this because my cheek does it and I'm not looking at the phone, so it leads to repetitive dialing.

Anyone else having this problem? Any fixes? I may just have a dud and will have to return it.

Thanks.

iPhone 4, iOS 4

If your face is pressing icons on the screen, then it sounds as if your screen is not blacking out when using the phone. If that is the case, then it sounds as if your proximity sensor is not working. Do you have a case on the phone? Do you have a screen protector on the phone? When you put your phone up against your ear, the screen should blank out completely. You may want to check that it is happening.

I am also experiencing this issue. It's like the iPhone 4's proximity sensor is not tuned properly or is not as sensitive as was in the iPhone/3G/3GS models.

During a call, invariably, my face will mute the microphone if i'm holding it with my right hand. If I'm holding it with my left hand, it will mute the caller.

This happens every single phone call. I'm not holding it far from my face either. It's literally 1 inch MAX from my ear at all times (it being the top of the iPhone near the speaker, where the sensor is).

They need to adjust this and release this in the first update that comes out. It's a terrible user experience.

I, too, am experiencing this most annoying problem. On the older iphones, when you held the iphone to your face the proximity detector would register the contact and black out the display on the iphone. When you pulled the iphone away from your face all the buttons would become visible and usable.

Now, on the iphone 4 the exact opposite, and worse, happens. When you hold the phone to your face the buttons are visible and easily activated. I've hung up on my boss twice already! When you pull the iphone 4 away from your face the screen goes black, your call is disconnected, and the phone freezes, seemingly for about 45-60 seconds.

PLEASE fix this ASAP, Apple! It's maddening.

I emailed Apple on this topic this afternoon. I have an appointment with Apple Genius on Sunday 6/27/10. I can answer the phone and carry on a conversation. When I take the phone away from my ear ..... the screen is black and I cannot complete any other tasks (like access the phone book or keypad or initiate the speaker phone. When my caller hangs up at the end of the call ..... I have a black screen ..... If I press the home button ..... I get the opening screen and the but the slide to unlock slider will not function for about three minutes. Interesting when the Apple Center promptly called this afternoon to respond to my email ..... I answered the phone ..... but could not initiate the keypad to select "1" because I put the phone to my ear for the first two calls. The third call I just place the speaker on and was able to complete the call.

During call, face is hitting Mute, End, Contacts, etc. buttons.
