Camera quality after housing replacement - sensor issue? (Pics inside)

Hi,

I replaced the outer housing on an iPhone 6 Plus that was severely bent, Other than the fact the whole right side of the LCD is much darker than the left (issue related to being bent?)... The camera is exceptionally blurry and out of focus.

What have I done wrong? It looks like I installed the sensor? wrongly and it doesn't seem quite right... Would this be causing the issue?
