Hi,
I have this problem too. It is so bad I feel I cannot use the phone any longer. 7 out of 10 calls I make the other person complains and eventually hangs up! I read with interest many peoples issues in the "echo" area including the debate around the type of case etc.
My phones versions are:
2.3.3 / I9100XXKE7 / 2.6.35.7-I9100XWKF3-CL276555 / GINGERBREAD.XWKF3
I now believe there are multiple causes to this issue and that I know some of them but not all of them. A definitive answer from Samsung would be most helpful and appreciated. Otherwise I am going to send this phone back and seek a non Samsung brand!
What I discovered this Morning with the help of some work colleagues is that 4 out of 4 Galaxy S II's tested appear to have an undesirable low volume speaker phone ALL THE TIME!
To check if your phone is affected by this piece of the puzzle do this simple test:
1) Dial your phone from a landline or wait for a call to come in.. or indeed make a call to someone.
2) Ensure the phone is in normal mode (not speaker phone mode) and adjust the in-call volume to max (Any setting from 2 up seems to cause the issue but lets go for the max setting)
3) Put the speaker (not the normal ear piece now, the one from where music or speaker phone comes)... put this close to your ear as possible.
4) Notice that you can hear the other person talking, albeit at a low level.
So... this speaker is very close to the lower MIC and must be the source of feedback into the mic, depending on the transmission characteristics of your protective case or indeed the way you hold the phone (remember the saga over the iPhone4 antenna???).
While all phones tested appear to have this speaker phone trait, not all tested have the echo! So there must be a software or hardware noise cancellation issue contributing (or not alleviating) the issue.
For me, if I cup the lower part of my phone (as if to protect the mic from wind) this instantly produces the echo as my hand assists the feedback loop. If I then hold the phone up higher and keep my hand away from the mic/speaker area the echo vanishes. SIGH
It may be that noise cancellation is working on some phones and not on others.
But the big question on my mind is why oh why would you rely on noise cancellation software to cancel out a feedback loop that should not be there in the first place. i.e. why is the speaker phone active (at a low level) all of the time.
And.... what is the solution SAMSUNG?
I have posted my software version numbers above. I will get the versions of my friends / colleagues and post this as it may reveal clues ^ o &

). So I finally had to bring a friends phone that worked with all my cases without any problems. So they decided to take a closer look. Finally , after a week they have found that there was an echo issue and replaced a part (which as they told me it was all the front screen compartment that held the microphones too) I ll try to find and post the part number in case somebody needs a reference to it. At the bottom line it seems it is actually a hardware issue , I had updated to 2.3.4 before I went to Samsung and that didnt solved my problem. I am just posting so that you can take any necessary actions to fully enjoy your phone because in my opinion the Galaxy S2 ..rocks...
