My iPhone 4S keeps switching to speaker phone when I make a call...

Something is blocking or interfering with the proximity sensor, remove any cases or screen protectors and see if the issue goes away.

I have te same problem. My iPhone i swiching to speaker when i make a call and I can't get out of speaker setting. I have to power off my iPhone to reset it then after 2 or 3 calls it is back to speaker. I have no case nor screen protector on my I phone.

same problem here now. iphone 4s and ios 5.01. after one or two calls my iphone switches to

Bluetooth Headset

Headset

Speaker *

and i can't choose my headsets anymore. when i still take the call it locks on the speaker but i can't hear or speak since it's all blocked

any solutions?

I am having the same problem, so frustrating and am keen to know how to fix it as it's extremely annoying....

I have used both iPhone 4 & iPhone 4s. I can confirm it seems to be only a problem with iPhone 4s. The only way to over come this issue temporarily when making a call or receiving a call cover the sensor. This needs to be resolved by Apple quickly, unfortunately the iOS 5.1 doesnt seem to be fixing it so far. Will hope for the best.

Hi,

Are you talking about the Proximity sensor? Can you explain to me where exactly it is please? I want to test if this makes any difference.

Thanks 🙂

The proximity sensor is directly above the ear speaker. Unless it is blocked by a case or screen protector it should be working.

Basic troubleshooting is reset, restart, restore. One of those should rectify the issue if it's not a hardware issue.

If it is a hardware issue, take it to Apple.

i was after posting following another thread here. tried the answer:

"My 'Settings/General/Accessibility/Physical & Motor/Incoming calls' setting was set to default. I figured this meant it would go to an active bluetooth device if it found one since the choices were Default, Headset, and Speaker. Apparently this assumption is incorrect. When I changed the setting from Default to Bluetooth it resovled my problem. Incoming calls now connect to the headset if it is active and to the phone when it's not.

'Bluetooth' is not an option. Do you mean 'Headset?'"

and currently it works - that's a iphone 4s issue i guess with headsets and with backups from iphone 4 or even 3g. apple should have a look into this. it's a but, not a feature. will post new experiences here...

Its the same old issue, dear me they still not sorted it out on the 4s, had this issue on the i4, and tried two different phones untill learnt to live with it. It is the proximity sensor and no Apple dont admit a problem. Test it by calling a number and moving finger close to the ear position, screen shouldgo black about 1 cm from phone, if not its to sensative, you will mute calls put people on hold etc as screen becomes live. Many of my friends have the same issue on the i4, so I guess its ongoing. Good luck with any resolution, if you find one drop me a line or wait for the i5 maybe, just maybe the re-designe may sort it out once and for all.

my (or paul's) solution did not work for a long time - same problems again. where is 5.0.2? where is apple?

Me too.

No case

No bluetooth

I make a call and it goes to speaker directly. I try to turn it off and it won't go off speaker but the icon is no longer blue.

Oh, and the person I'm trying to talk to can't hear me.

If I have the head set (apple standard delivered with the phone) it doesn't matter. Putting it into or out of the phone doesn't make a difference.

And it happens sporadically.

Funny thing is, -everyone- and their mother said it was hardware issues, or otherwise something that was -my- problem. Then, strangely, there was an iPhone update and it was fixed to never happen again. That speaks software issues to me.

Just had this same problem and found that I had to go to Settings, accessibility, call routing and select 'automatic'. Mine had set to via speaker.

Hope that helps someone.
