Recently, my iPhone 6's camera lenses cracked. I plan to use my phone for another year, and since I need to sell it, I figured it is a good idea to repair it. My understanding is if I take it to Apple for repairs, it'll cost $300+ CAD It doesn't affect photo taking that much, unless you shine light directly into the sensor.
Here's a sample shot with the cracked lens with no light shining directly at the sensor:
As you can see, the difference is probably not noticeable at all. Here's where you're going to start having problems though:
The angle of the lines around the light sources correspond to the angle of the crack. Also, you can see the effect of it at the bottom right hand corner.
There are tons of tutorials on the internet on how to do it. The one on heating up the back and replacing the ring seems like a terrible idea, since it's questionable on whether it works or not. Another way is to take the phone apart and poke out the old lens. However, I still need to buy replacement parts, which will probably run me about $10-15 (Plus the cost of whatever glue to use). It seems that all the replacement lens on eBay and Amazon are cheap Chinese plastic parts and not quality glass. Also, all the parts are shipped from Hong Kong or China, which will take 4-6 weeks to get to Canada. Therefore, I held back, and since I am in Hong Kong, I decided to go hunting on the streets to see what I can get.
On the streets, I cannot find anything that I want, which is unfortunate. However, there are tons of shady repair shops on Apliu, so I asked to see how much they want to replace the lens only. After all, if they can do it for half an hour and they probably repair hundreds of phones per day, they probably won't wreck anything lol.
One shady shop was willing to do it for $100 HKD (About $17.50 CAD at today's exchange rate) and was willing to do it on the spot. I stood there and watch him do it, in case he steals some of my OEM parts for fake ones lol. I was also curious how he's going to do it, and what parts will he be using (After all, fake Chinese parts are better than a cracked lens). What he did was he ripped a lens off a wrecked iPhone 6 and put it on mine, so I guess he is using OEM parts Curiously, he only took the lens out with his tweezers, and did not punch out the ringed part. Anyway, $100 HKD and 15 minutes later, everything was repaired perfectly.
That's a photo I took to test the camera after he gave the phone back.
