I have a problem when i use handsfree earphones, there is such bad distortion that people cannot hear me. It isnt the headset as i have tested another pair and it does the same and it works fine in my other phone. Im not sure if i did something in the service menu as i was trying to increase volume on my headset for music, but this resets with a soft reset so it cant be that. I recently upgraded to ICS and thought this would solve the problem but it hasent. I do not really want to do a hard reset as this will take ages to back everything up and put it all back to how it was!
I am also unable to access the Service Menu Audio setting now, nothing happens when selected, all the other options work, again i dont believe this is the problem.
Has anyone had this problem before and if so what is the solution. Thanks for your time and help.
