Just got my Galaxy S 2 a couple of weeks ago and everything is almost working perfectly…
When I am calling someone the phone sometimes does not turn on the speaker and mike. The call always goes through no trouble with that at all.
The phone is ringing to whoever I am calling, but the one I am calling cannot hear me and vice versa. I noticed that every time I make a call that actually works and goes through without any problems, the phone makes a little dialing sound and then I can hear it is ringing with the normal ringing sound. When the call does not work, the dialing sound and I am not able to hear anything, I can however see when the person I am calling answers the phone because the phones shows the small clock indicating how long I have been talking to person. So the problem lies in both the mike and the speaker because the one I am calling are not able to hear me either.
I tried to see if I could provoke the problem so that I might be able to send it in for a repair, but the mistake is very random and comes and goes as it pleases. Sometimes it works perfectly for days and other times it makes the mistake many times in a row.
I tried to test the phone to see if I could solve the problem by calling my girlfriends phone. At one time the mike and speaker actually started working 30 seconds into the call by just pressing all the buttons I was able to… but it only worked that one time.
Does anyone have an idea towards what this problem might be and more important - how do I fix it?
