Had my doubts.

My Problem

I had my iPhone 4s in my pocket and fell into the pool while I was cleaning it. After that, as other users have described, the camera flash stayed dimly lit and the battery life was extremely short, but the phone worked fine. I tolerated this for a little while and then got an iPhone 6. My 10 year-old son was always a fan of my 4s and now it was his to keep but the battery life was awful.

My Fix

I found fixit.com with a simple Google search. I surfed through it and decided to replace the rear camera and battery. For a little over 60 bucks I got the replacement parts and tools along with the liberation kit. I followed the instructions on the site and now my son has a functioning 4s!

My Advice

Be very careful and deliberate while doing the repair. Make special places beforehand for all the little screws that have to come off. I'm almost 50 and I wish I had some magnifying spectacles or something to magnify the whole situation. Everything you are dealing with is extremely tiny.
