Change A Upper speaker

@manankhurana iFixit does not yet have a guide for that. For now, use the guides from here you can use the one for the internal or the external speaker. You did not specify this but it sounds like you are meaning the internal speaker.

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 the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
