ctiruvuru got the same problem, "the internal speaker, speakerphone or headset does not work while making a call - I can't hear the other person but they can hear me fine. Also, when I receive a call and after I answer it, there is a delay of 3-4 seconds before it's actually answered. The headset and speakerphone work fine if I use media player etc."
The IMEI number had changed into 004400003501112. I tried flashing all the rom I've found but the problem still remains.
Does anybody know how to solve this?
