Why the speaker and microphone are not working
Hello, this is my first question on this website, first of all I am verry glad that we "phone technicians" we can find this awesome place to change our experience and to improve it as well.
So now back with my question... I got an iPhone 7 after a screen replacement(in another shop) and I am just wondering what could be the reason for not working the microphone, ear speaker and speaker, all in the same time, the button is also off when I make a call...
I have already replaced the ear speaker but no effect, I also analyze the flex cable and looks ok.
Some hints from better technicians?
Best Regards,
Razvan
