Chosen Solution

Hello guys, I got iPhone 7 and i clean rear camera and it’s now working perfect. But, front camera is blurry. (if you want I’ll send image). I opened iphone, clear glass and camera itself - nothing. I changed iPhone 7 front camera with new one original from other iPhone 7 (iCloud locked only for parts) and results are same.

Any help please ? Thanks.

If you replaced your screen, it can be excess of glue( If was a aftermarket Screen), you can try the camera without installing it on the Screen and if is clear, the Front Camera hole/windows is the problem.
