2 - 5 minuten
I have had my company-supplied iPhone 4 since 2011. I did not take the best care of it and thus scratched the back panel (and camera lens) to the point that the camera was no longer useful. My company would not provide an upgrade because email, etc worked fine. So I took it to the local Apple store where the associate was not very helpful. I guess he was disappointed to have to work with a dumb customer that still had a iPhone 4. He gave me a quote of about $150 to have the back panel replaced and could not guarantee that would fix the camera. So, I checked on eBay for a replacement phone and found the same type of price gouging. I finally did a web search and found a simple YouTube iFixit video that convinced me that a simple back panel replacement would solve my problem so I bought your very reasonably priced kit.
No problems at all. It took all of 5 minutes and my phone now takes non blurry photos again. What a simple solution which I could have avoided had I just protected my phone to begin with.
No real advice about the repair as it was so simple. For those who need it, make sure you have a second set of hands to hold the magnifying glass as those screws are tiny.
