As the title says, when someone is talking with me on the phone he hears himself in a way that makes talking very annoying.
Its not the first time i have this problem, a month ago i had the same problem i tried everything i can but only restore solved the problem.
Now, a month after, the problem is back. I can solve it by restoring again but i hope some1 have a better solution then restoring my iphone every month.

thanks.

Update: some1(that have the same problem on other forum told me that lowering the volume solves this, and it did. i just cant understand this, its not a cheap crappy phone, why dose it happens?!
