How important is the ambient light sensor filter?
Heeey everyone :)
After looking around the net I haven't found an answer to my question, so here goes..
How important is the ambient light sensor filter (white square filter) and what are its functions?
Some people told me it's a optical filter and not necessary, while someone else told me it's a light diffuser.
On white screens it's a dot instead of a square.
Questa è una buona domanda?
