Before I sell off my otherwise well functioning iPhone 5 in favour of something shinier and pinker, I'd like to replace the rear camera which has a large amount of dust accumulated, making photos unusable. Replacement cameras range in price from $10-$40. Reviews are all over the board. The repair itself is straightforward so I'd just like to hear from people who have done this repair themselves, have a discerning eye and are happy with the quality of the photos taken. Which camera did you buy? Are they all from the same manufacturer and simply marked up to different amounts?
