When I make a call the person doesn't here me well. I recorded the call and when I listen the record, it sounds like crap.
I recently replaced my screen, did I brake something?
Which part do I need to replace? Is it the big black part in the bottom?
When I put the speaker on to play music everything is good..

Thank you
