Hi, I have an iPhone 7 in which I plan to replace the logic board. I was wondering whether it was necessary to replace the waterproof/display adhesive when putting the phone back together. Thanks
It’s not strictly necessary, the screen fits nicely on the housing even without it, it will just be less splash resistant than it would be with adhesive. However, unless the adhesive is machine installed under controlled factory conditions on a perfect housing, the original out of the box water resistance will never be restored again.
