5 Why others cannot hear me when I am on speaker?
I searched and I found the same problem but vice versa.
When I hear the other party through the earpiece all is well. When I turn on the speaker (speakerphone) the other party cannot hear me.
I know that the opposite happens a lot.
Any suggestions on this one?
Do you have a case on the phone?
