I self-repaired the external and internal screens on my own device, but since doing that, one of the mics doesn't work anymore.

I can talk on the phone normally, but video calls and speaker phone is a no-go anymore. I think it's the top one, but I want to replace both just in case.

So, which parts am I needing here?

The mic-holes are, when looking at the back, left of the USB-C Port and the only hole on the top of the back part of the fold.

Thanks!
