Earpiece not working after screen replacement

"Here's a few steps you can try to resolve your issue:

- reseat the earpiece so that the contacts line up.

- check for any visual damage to cable or ear piece.

- if this doesn't work, you may have to try and replace either of the parts.

- also, try cleaning contacts with 99.9% isopropyl alcohol, as oils from your fingers can interfere with things."

Try reseating the earpiece. As there are gold connecter on the proximity flex and gold connectors on the earpiece that need to be lined up.

I had this issue today, After changing the screen multiple times trying to figure out why I couldn’t get any sound out of the earpiece- I tried reseating the ear piece and figured I just kept installing it wrong I finally cleaned the connectors and the issue was solved! It’s Amazing how sometimes the simplest things is all that matters!
