The problem only happens when I use a phone cover (currently using the Case Mate Tough case). I think it has something to do with the noise reduction, as the problem stops when I turn this off.
Does anyone know if this is normal or if the handset is faulty? I've tried different phone covers but the same thing happens.
I'd love to be able to switch off the noise reduction permanently but there doesn't seem to be this option.
I had that same problem too. No case cover or anything. Everyone I called complained about that same thing.
Updated my two weeks old I9100 with Gingerbread 2.3.5 to ICS 4.0.3.
No voice echo problem anymore and ICS works fine. Flashing custom ROM can void your warranty though, but there is a solution too.
