Bottom left speaker broken.

Hello,

Does some one know if the bottom left speaker/(microphone?) is fixable?

Since a month when i call people they hear me verry silent, like i am far away from the microphone. This is with normal calls and calls on whatsapp. Even when i put myself on speaker it does not work. When i check ifixit i only see the replacement for the bottom right speaker.

I have been to an apple store and they tested my phone, the diagnostic said that there is a problem with thebottom left speaker. Now they wanted to fix this but since the i got a small shatter of broken glass at the back of the iphone XS the warranty failed… They still can fix it but i had to pay 591 €…… That’s why i’m posting here, to see if some one else got this problem.

Thanks.
