iPhone camera not focusing well after screen replacement
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?
