Chosen Solution
I recently purchased the screen replacement full assembly for my iPhone 6, I followed all procedures but it seems like the screen does not fit completely into the phone, its edges are up and the camera does not function except for the video. The screen seems to be forced, when I barley add any pressure the side acts as if im adding too much pressure.
You could have a low quality replacement screen or your housing is dented. See the attached image for an example.
It’s a minor dent but it pushes the screen frame down by almost 1 mm. If your housing is damaged, which is not uncommon when a screen is broken, then you need to hammer it (very gently) back into place. I like to use a metal spudger like this . You can use the round end for the corners and the flat end for the straight edges. Be gentle as the aluminum housing can break very easily.
You can get a High-quality iPhone 6 LCD screen replacement in Etrade.
