Today I have (mostly) successfully replaced my broken screen on the iPhone 6s plus. Everything works except for the back (main) camera, It’s not focusing. I think it might be because I might have been using excess isopropyl alcohol to clean the old adhesive. I have removed the camera, tried to clean it and put it back but for the moment it’s not focusing well. How can I clean this camera? It really looks like there is dirt on the lens and that’s why it’s not focusing. Or perhaps I should wait for the alcohol to dry completely?
if its the slightest bit smudged or has oils (from your hand; or anywhere else) make sure you clean the inside with a microfiber cloth Microfiber Cleaning Cloths
if its the back camera, has notting to do with the screen replacement , the camera is damaged and must be replaced. good luck.
