http://forum.xda-developers.com – Ok.I am in a totally crazy situation.When i call somebody they won't be able to hear me and i can't hear them.Basically in a call my mic and ear piece do not work. However if I put it on Speakerphone,both mic and speaker phone works.Also I can't play music through the speakerphone but I can play it through the headsets that I have.I am guessing that this is a problem with the chip which fails to understand when a headset is plugged in and when it is not. Now my issue.I don't reside in US from where I bought this device. Right now I am using an app called Soundabout that manually changes the s (HowTos)
