ios 7 proximity sensor not working

Really? Then why does it work perfectly, as it always did on my 4S.

Lawrence, either you are very lucky or you are a genius, but being a smart alec does not make for nice play on these boards. Get a grip, OK?

My two 4s are messed up. Never had a problem before iOS 7.

I'm sorry you didn't get my point. 200 million people have updated so far. If it was a problem with i OS 7 you would see tens of thousands of posts about it. There are a few dozen. It's unfortunate, but it is not an iOS 7 problem generally, and if you are planning to wait for a fix to iOS 7 for what is not a generic defect you have a very long wait. Try the suggestions in this thread that have fixed it for other users, and if none of them resolve it take it to an Apple store.

Hi Lawrence, i've many Apple devices from many years. Never i discovered a trouble when updating OS. But this time i think to give my contribute writing of a possible bug. However i will take my device to an Apple store as you suggest.

Turning off Siri and resetting all settings fixed it for me. iPhone 5.

Settings/ General/ Reset/ Reset All Settings. Hopefully, this will be mentioned as a bug fix in iOS 7.0.3 or 7.1.

Thanks! That worked for me!

Thanks chotti1! That worked for me too!!!

I have been having the same problem,

I keep putting the phone on loudspeaker, dialling numbers or making a facetime call when using the phone,

I made or recieved 58 calls today and this happened on nearly all of them, its driving me nuts.

Just like a previous poster, it starts off ok but then the screen reactivates while I am still on the call and then its beep beep beep beep beep as I dial with my cheek.....

Tried a few resets, also re set all settings just now, hope this sorts it!

Checking in. iPhone 4S, 7.0.2, proximity sensor is failnig. Worked OK with 6.1.4

# temporary solution of this bug (on ios 7)

when you receive call, slide "slide to answer" and wait 1~2 second.

and move your phone to near your ear. and receive call.

# appear again this bug

1. sleep your phone

2. when you get a phone call from

3. slide "slide to answer" and quickly move your phone to near your ear (almost sametime do that)

or

3. lap proximity sensor by finger and slide "slide to answer"

you lap proximity sensor and calling, but screen on and can touch it.

Having the same problem quite annoying. Regardless of the 200 million downloads it is an issue after the iOS 7 update. Apple needs to sort it out.

Same problem for me and my wife. Both have new 4s iPhones that were just replaced a month ago at apple store due to defective sleep button on one and screen problems on another. Both phones worked fine on ios 6.1.3. Since ios 7 every call gets messed up by proximity sensor not working. Actually just happened as I got a call in the middle of typing this post! Placed someone on hold with my ear. Have tried above solutions with no success. Seems like this should be an easy fix for apple. If the settings were changed they just need to revert to ios 6 settings. Hope to see this resolved soon. Very annoying

A fix was posted above. Turn off Siri, then Reset All Settings under General. The Reset is not as drastic as it seems. Doesn't even affect assigned ringntones.

Duffy, that is not a fix, I have tried all the suggestions listed and I am still having the same problem,

If anything it is worse since re setting the settings, plus I actually use Siri so hardly a fix having to turn off a useful function. Come on Apple, sort it out!

Tried turning Siri off and also doing the reset as suggested but this has not fixed the problem. Apple really needs to address this issue as it is quite annoying that your speaker phone suddenly comes on during a call.
