I've read alot of discussions that suggest auto brightness isn't active on arc s. Is this true? If so, what is the purpose of the ambient light sensor (camera)? Is there a brightness setting (e.g., 80%) that enables auto bright /autodim?
It seams like it very's some in between different units, a bit unclear though if it's depending on software's or on markets. To be able to get it to work by 100% you have to set the light to 100% also.
Try it out and let me know!
