Hy, i have a little problem. When i make a call in normal mode ( speaker off ) my microphone works but when i put it on (speaker on) my microhpone wont works. It's a little bit strange. When the speaker is on i can hear what that person said but he can hear me.
Thank you. Sorry for bad english.

Try to clean the switch for external Speaker, Use a little alcohol isopropyl for to clean.
and try again. However you must test the speaker with a DVOM , normally the resistance for coil speaker will be around 8ohms.Replace if the value is Out under the specification
God bless you
