A year after washing my iphone 5 (and having it all work just fine- except some camera smudges) the external speaker stopped working.
So- I watched a few hours of YouTube and thought- !&&*, I can do this. And yes- I can. In fact- anybody can. Super easy.
I abandoned the iFixit steps and went straight to the speaker area. Found a YouTUbe video that covered the short version- It went great. No issues at all.
From the one time I opened my phone- I'd say do the short version.
Here's the video I found most helpful.
It's like 5 steps vs Ifixit's 25 steps. And- it's working.
I also need to replace the rear camera but that's a bit deeper so I'm holding off for now.
I think there are cheaper parts out there than iFixit but it all went so well, I'd use them again.
