Chosen Solution
Autofocus can’t focus with rear camera. This results in blurry pictures and “shaking” pre-view. I have noticed that the lens in the rear cover has a scratch which probably causes this effect. Should I replace the whole rear camera (and includes this replacement also the outside lens?) or is there an option to replace the rear lens only ?
the rear lens is integrated into the back housing for a 6S. it is, by all means, possible to do, but much more difficult to remove than most people give it credit for. my suggestion would be as follows; order both pieces. (the lens would only be another 99c. or so.) but try starting with just the camera replacement, in hopes that it is a module failure, and check if that fixes the issue. if it doesn’t, move forward from there.
Thx for you quick response. one question left. Q: Iphone is remotly analysed by Apple Support and reported no hardware failures. Would you advise to skip the camera replacement and go for the rear lens only ?
