Iphone 4 people cant hear me during calls.

I'm now on my third iphone 4 with this problem. I'm starting to go insane. Nothing helps.

Same problem! Not every time but often enough!

i went into the apple store today, AND OF COURSE IT WORKED WHILE I WAS THERE. now i'm back at the office and it's like every other call that it functions.

FML.

my iphone is also having same problem, have tried resetting it, havent tried restoring yet. It was working fine for last 6 months. What else can be done?

Also my facetime works fine. so i dont think there is a problem with mic...

Don't worry I'm having the same problem 😟

My wife is having the same problem with her iPhone 4. She did drop it however. I have taken it apart to investigate and I believe its the sim card connector. No one can hear her at all when she calls and mine works fine. I swapped our sim cards and her phone worked perfect (with my sim card) until 5 minutes into talking. I figured there must me a loose connection in the sim card connector. I ordered a new one online and will see how it works. If I have any luck I will tell.

This may work. It worked for me. Go into Settings, then choose Sounds. On Ringer and Alerts, I put the volume down to zero and then all the way up. This solved the problem. (At least for now)

Thanks Bluerunner. It worked for hers too for now. Hopefully its permanent.

Unfortunately same issue also for me 😟
It seems to be ok after a restore, so it was software problem not hardware.

I would like, and pretend as costumer, to have a GOOD software update without stupid alarm clock bugs, and stuff like this one.

Same issue, problems here. Apple has replaced iP4, worked for an hour, then back to same prob. AT&T says needed new SIM card; took it today to AT&T, replaced SIM, they called me in the store, they couldn't hear me. Sending me back to Apple today (70 miles roundtrip).

I'm a longtime Mac owner, Apple customer. This may be the final straw.

I am having the same issue. I had to replace my iPhone 4 due to the GPS not working and the brand new phone had this issue the minute I started using it. I am going in there tomorrow and getting a new phone. If the issue continues I am switching to Droid. I was the biggest iPhone fan just 2 weeks ago, but am now very anti-Apple.

me 2... my iphone bought from hongkong on AUG. i tested my mic and found it is work..i dont know why, but i searched forums in China, and i think there are so many ppl are facing same thing as us. Any news reported this problem? and i think it is not about the software.

im having the same prob... went to an apple store, had a meeting, they said they fixed it, worked for a few calls then stopped again, this is b.s.. i've restarted, restored, all the things on this topic, phone hasnt been out for a yr yet and the apple site wants me to pay to have someone look at my phone for the prob.

I have the same problem since last week. When people cannot hear me, I turn on and turn off the speaker immediatly, then they can hear me and the the phone is good for a day. And the second day have the same problem and i did the same thing again........
