How to repair phone speaker?

@tazz47881 not much repairing to be done since it is water damaged. I suggest that you replace the speaker. Since iFixit does not yet have a specific guide for this, use the one from here It was written in French, so use a browser that can translate it for you.

While you have your phone apart, do yourself a favor and check for water damage (corrosion). Clean the inside of your phone, board/etc. with some +90% isopropyl alcohol and some cotton tipped applicators. That way you may avoid any delayed failure cause by corrosion

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.

Repair is War on Entropy!
