4. Turn the phone upside down, adjust the brightness to the highest level, place it in the carton, and align the light source with the lens.
When fixing the magnifying glass on the carton, make sure it is sealed and no light will leak out. When you turn on the phone and close the carton, you need to fine-adjust the position of the phone so that all the heads can be projected onto the white wall. .
