Iphone 4 people cant hear me during calls.

Team. I hd the same problem and I belive that willable1 had the fix for this problem. I closed all my apps and made several calls and it seems that the problem was solved. In my case i beleive the app that is causing the problem is iheartradio. My problem started after an update. Hope this is a fix and helps you. Kudos to willable1.

this is very depressing reading - at the end of September My 6month old iPhone 4 started crackling when I was talking to people, making it impossible for them to hear me. took it to the apple store and after attempting to restore it without success they replaced it. That was on the Sunday, by the following Thursday the new phone was playing up, people couldn't hear me after a minute or so - I could hear them perfectly, if I turned it off it worked for a minute or so and they couldn't hear me again. took the phone back ant they replaced it again. now on 3rd phone ... But they said if it happened again to contact carrier O2. It happened almost immediately, contacted O2 they sent out a new micro sim - it's installed - yesterday - still got the problem - driving me nuts.

will try head phones, pinching etc and will go back to the apple store again and show them all the posts.

This is hardware issue, audio controller shoud be rebold. If your waraty is valid go and get to replace it.

My waranty was void and I fix my for 100Uusd at here at cell metro.

This is only fix!!

found the answer on youtube, ten year old kid!!! its the noise cancelling microphone issue. The small hole next to the headphone socket. I used a very thin safey pin and gentle pushed a couple of mm into hole. I also used a couple of strands from a tooth brush. I am not sure if it just cleared some dust but it worked straight after. I also gave a couple of blows for good measure!!. Youn can tell if its the mic issue by pushing down on the hole area when making a call and the sound should come back on, if it does try the safety pin.

WOW, that's a very good find, I'll try to clean it right away with a thin wire, I'll keep you all posted

Whats up guys,

My iPhone 4 has this exact same problem, no one can hear me during calls. I smacked the phone around just a bit and after a couple hits it works, but only for a minute or two, then it goes back to the mic not working.

I tried cleaning it and everything like you all did, still no luck.

My apple warranty has expired, I wanted to ask all of you that If I take it to apple, and the tech screens the phone, and he/she finally comes to the point of replacing it, will I have to pay for it?

I find this widespread problem ridiculous to say the least..

Took it to the genius bar (third time, third phone) and they took the back off and tightened up all the screws and so far so good......!

I bought my iPhone 4 almost a year ago. After one month people told me they couldn't hear me during the first 30 seconds. They said it was like I was in a kind of basement. I didn't dropped it, it didn't get wet, ... no explanation at all.

Yesterday, I installed iOS5 and did some test calls. Till now, all my calls were great! Everybody heared me well!

Hopefully installing iOS5 is the solution to this problem for the rest if you too. Let's hope it will keep working now.

Wannes

Installing iOS5 did not fix the issue with my phone. However I think my issue is different than wannesc because no one can hear me at all.

The genius I've talked to said it was an issue with the sim card functions (either the sim itself or the sim reader - which kind of made sense since the issue with the mic is only when making call) and I should swap the sim to see if it fixed the issue.

It didn't.

I wasn't the only one with the issue at the bar too

I purchased a 4S on Monday and the first call I made wasn't able to hear me until I was on speakerphone. Then things seemed okay until this afternoon; it's very hard for callers to hear me (although I can hear them well) unless I'm on speakerphone. Went back to AT&T just now and they would have exchanged the phone but are out of stock. They called a few other area stores, but no luck. The rep suggested going to the Apple store for an exchange since they have a good supply of phones. I just made an appt. for Saturday morning, since that's the first chance I will have to get there. Hopefully I will get a new phone with no problems.

i have an iphone 4 and have the problem people cannot hear me when i make a call 😟

got an appointment with an apple genius tomorrow... lets see what that title entails!

use my phone for work and dont know what i'll do if it doesnt work anymore!

do apple always offer you a substitute if they cant get it working?

Same problem, I have tried every suggestion except the pin hole thing and nothing worked

been cleaning my iphone with a toothbrush for an hour but still no improvment.

really hoping it gets sorted out tomorrow!

Did you clean the small hole at the top?, introduce a thin wire and try to take some dirt from inside. It helped a little, but at the end I ended up with a galaxy S II. Quite happy right now with the new phone

My problem is fixed (people couldn't hear me but I could hear them) this is how

Phone that had been ok for 5months suddenly started to crackle and people couldn't hear me

(didn't know at the time but the sim card hard become 'dirty' and wrecked the phone)

Got a replacement phone but put the dirty sim card in = another wrecked phone

got another replacement phone put the dirty sim card in = wrecked that so still a problem.

Got a new sim card and put it in the phone but the phone was already damaged so no improvement.

Finally got another new phone put the new sim card in and bingo it worked.

So new sim card in a new phone is the answer. thanks apple genius bar in Cardiff. it took a month and six visits with six geniuses, but we got there in the end!
