Microphone and Earpiece not working in-call, unless loudspeaker on.
I have inherited a second-hand Note 3. During a call the earpiece volume is very feint and the person on the other end of the phone cannot hear me at all (akin to being under the sea).
When Loudspeaker is put on, everything works fine.
I have completed a factory reset, I have checked all settings, I have performed all updates. Nothing seems to work.
Is this a case of changing the components? Are they linked together on the board?
Thanks for that.
I have completed a tear-down and found that the earpiece was blocked with brown gunk - likely to be dust and sweat. This has rectified the issue with the earpiece.
What I can'y understand thus far is why the Microphone works in Loudspeaker Mode but not in normal mode.
Do you have any idea why this would be?
Is this a good question?
