Chosen Solution
I recently replaced an iphone 7 screen with no problem other than the initial adhesive difficulties getting started. Once everything was complete, I discovered the front facing camera is very blurry. It’s impossible to even make out what the camera is looking at. The rear camera operates perfectly. I took the phone apart again to clean the camera lens and the glass with no avail. Why is this happening and how can I fix it?
usually the camera lens has seperated from the camera’s circuitry, and exposed the camera to light. overexposure will fry out the camera and make it blurry. best option here is to replace the camera flex. (fixes it the majority of the time for me)
