My z fold 3, had a back glass change after which all the pictures I take have blurry (like potrait bookeh) at the edges. This persists even when I am using expert raw app. If anyone with the same issue know a solution, I would appreciate it. I expected the software to sharpen all the pixels, but this is strange experience to me.
Looks like it's the hardware they replaced with, you should make a complaint and ask them to redo to replace. Probably they did not use original parts. Not the phone's fault software far as I can tell.
Thank you @Star_girl. I have to confess that I just changed the back glass myself with the camera module not touched. Initially guessing it's some kind of dust, I cleaned the inside of the lens glass but still no impact.
