When put phone on loudspeaker, mic does not work. I have updated to orieo but the problem doesn't solved.
Did you mean that your mic doesn't recognize your voice when the loudspeaker is working or making sound? If that's the case, then it may be because of the sound... both the mic and the loudspeaker is situated at the bottom of the phone so the mic will pick up whatever sound is playing on the loudspeaker, hindering other sound such as your voice.
Try pausing or silencing any noise that the microphone may pick up.
