( HELP ) K750i front speaker working but no sound when making call.

[kuniosti]

My K750i have white screen of dead, after update/flash Main+FS version R1DB001.
After recovery, the phone is working now.

But the front speaker/earphone no sound when making call. Wired hand-free and Loud-speaker (back) work fine.

Enter test mode with *>*<<*<* and do Earphone ( front speaker) no sound...but when I do mic test, I can hear the play back at front speaker.
I also able to hear start up tone and shut down tone at front speaker when on/off the phone.

The front speaker only no sound when making call, any idea? please guide.
Thanks in advance.


SOLVED, Thanks
