Outgoing sound (internal and optional mic) drops out on iPhone 4
Hi Guys!
This one is probably for an iPhone 4 expert.
The problem:
Outgoing sound (my voice), suddenly and unprovoked, drops out during calls. There is a small static sound, and sound is gone. The person in the other end goes "Hello, hello.." and then hangs up.
This will happen no matter what mic is used. I tried all 4 sources:
Main mic (bottom right)
Speakerphone mic (located in headset jack) Bluetooth
And of course, an ordinary minijack headset
Solutions already tried:
1. If I bump the bottom of the phone on a table, or another hard surface, sound will be back for a while, but usually not for long.
2. I have tried to change the docking module, with the standard mic attached to it = NO LASTING CHANGE!
3. I have tried to take the phone apart and assemble again = NO LASTING CHANGE
Both solutions seemed to work for 30 min or so. Then, sound gone again!
I have tried to "irritate" the jack plug, to see if it was stuck somehow, but it didnt seem to change anything.
I have checked all ribbon cable connectors with a microscope, and they seem fine. I could understand, if it was in the big dock-connector at the SIM tray that was causing this, but the coming and going of sound, with bumping the phone don't lead my suspicion to a bad connection in that sort of plug. Especially not since I changed the whole dock module, and thereby also the plug.
Edit:
It records LONG memos without any problem, so the problem has to be in the "transmission/sending" part of the phone, rather than in the "mic department".
Unfortunately, I bought this phone 2'nd hand, and didn't get a reciept so warranty exchange is not an option. Futhermore, I had in laying on my shelf for a month before I got around to use it, so it's useless to complaint to the previous owner (who, I am pretty sure, knew about this problem, based on the fact that the problem is constant and persistant).
I REALLY hope some iPhone expert can help, as this seems to be a problem that seems hard to solve.
Thanks in advance!
Ist dies eine gute Frage?

Hello! Did anybody end up getting this fixed? I've been having the exact same problem and it's been driving me crazy. I'm also in the same boat in that the Recording program works without fault, but only on calls will it drop out. I called my landline to test and it will cut in and out.

Does anyone know any repair centers for this kind of issue in the MA area or via mail order elsewhere in the US?
