I cracked the camera glass (housing) on the back of the phone. Is it possible to open the phone and replace without having to swap the entire back of the phone?
Hello sunsetblow, Sadly, you cannot just replace the camera glass on the back of your iPhone 8. Upon doing some research, it is not like the iPhone 7 where you can just pick it out, then put it in a new one, but the lens is attached the to entire glass frame meaning you would have to replace the entire back. Not only is this a very, very difficult repair, but it will get rid of its water resistance and possibly ruin your wireless charging capabilities if not done with extra caution. As much as I am into fixing phones, I would not recommend you do this repair yourself, but to take it to Apple or a repair shop you trust and have it fixed. Apple will charge you a lot, but it will guarantee and good repair and keep its water resistance. A 3rd part repair shop will not keep its water resistance, but maybe slightly cheaper. Hope this helps!
