Issue with Proximity Sensor during calls

No this is definitely a problem not a change and I'm sure we'll see a software fix for it.

The call screen command buttons seem activate without the screen actually lighting up.

I'm now routinely pressing the home button when I begin a call which seems to stop it happening.

This is so frustrating. I am "accidentally" hanging up on 80% of my voice calls. Earlier today, while on the phone with a university, I somehow with my cheek hung up on them and then started dialing one of my friends numbers.... This phone is currently unusable!

the guy who mentioned about placement of the sensor makes a lot of sense. I know I usually talk at an angle and the sensor is easily exposed and would other wise be covered up on past models. The only is that that is when I talk on the left ear as for the white ear on previous models the sensor would be exposed.

So I think its a combination between sensor placement AND over sensitivity of the sensor. may have to buy a hands free blue tooth. honestly not a bad idea anyways because its safer while driving.

Does not make it right and apple should fix this rather than us finding ways to live with it!!!

I am currently having this issue....

1st call I made I kept hearing as if someone was dialing a number...only later did I realize it was me hitting it with my cheek over and over again.

2nd call later that night i looked up my contacts and called a friend. Was talking with him and then when I was talking to him it started dialing somone in my contacts that is the least person I would want to call right now and made a three way call! I couldn't believe it.

Basically I can't risk this and can't keep ending calls or dialing numbers or hitting buttons....if there is no software fix for this....I may actually need to return this within the 30 day period. I'm not going to risk this potentially being a massive hardware issue and not software.

I'm also having this issue. I'm face dialing left and right. It's really quite bad at the moment.

I got my iPhone4 yesterday from Tesco in UK (Pay monthly plan). Though the bumpers look cool but if its to hide a design flaw then it would do justice to get it free for all the defective sets.

In between, I am left handed so tend to use my phone right handed and till now not affected that much. But the problem can be reproduced at will especially when browsing in general that the most common contact point with the phone.

Fingers x - Waiting for some official press release from Apple.

Thanks

Resetting all my settings fixed my sensor problem. Thanks for the advice.

I am facing the same problem with Iphone 4 proximity sensor i have initialized facetime / and also ended my phonecalls WHERE IS THE FIX for this 😟

I have the same problem with proximity sensor...I hung up 5 times and pressed keys accidentally...very annoying....I hope they fix it soon.....

I am also having the same problem. This is very unlike Apple. When are these problems going to be fixed?

Too bad they are messing up the little things....things that weren't broken before. I expect a bump in the road for new features but customers also expect old features to continue working.

I'm having the same problem. I'm talking and the person says they can't hear me.... I face-muted them. Also constantly pressing numbers with my cheek while on a call...not professional at all since I use this for business.

I have used every single model of the iPhone since 2007 and never ran into this issue. Until today. This was my first full day using iPhone 4 and I have hung up on people, put people on hold while dialing other contacts, and randomly dialed numbers from the keypad. I tried resetting the settings of the device as was discussed in this thread but I haven’t seen any difference. I did not have the device in a case during any of these issues. I did restore this phone from a back up of my 3GS during initial set up. I wonder if that’s causing the issue for some of us?

Unlucky for most of you that are having problems. Mines working perfectly I've spoken to mates and o2 using my phone since yesterday morning when I received my iPhone and I have no problems the signal goes down when I hold the left side of the phone in my house but if I hold my phone with my left hand in work it stays the same. If your having problems go to apple store tell them the problem they'll check it over, if there's a fault they'll swap it for you that's how great apple are!

I'm also having the issue and it's frustrating for me (as well as the person in the other side of the call). My face constantly is either initiating FaceTime, Mute, End Call, etc...

And I don't want to get an email from Steve J. telling me my face is fat because it's not.

Software update ASAP please!

I have the same issue.

Last night the screen kept turning on during a call, causing concern (and slightly blinding me in the dark).

Today, my cheek activated the Speaker-Phone while on a call.

This never happened with my 3GS.

I hope it's a software fix and not a hardware recall!
