Back Camera not sharp after replacement.

Hello,

I have a problem with im iPhone 6. I damaged my original lens and camera so i replaced it. But now its not working correctly. I can't focus on things that are closer than 2 m.

Everything else seems to work correctly (colors, sharpness in the disctance)

I have no clue how to fix it. I also tried a new camera to see if my camera got damaged by UPS.

Anyone got this problem and fixed it?

Greetings
