I think Amazon should consider a careful look at the auto brightness feature, which works just the opposite way it should.
The Kindle device screen technology is different from a smartphone screen. It is light reflexive, not light emissive. Because of the e-ink technology, it works reflecting part of the environment light (just as real paper does), the opposite way of a phone screen, which throws light (radiation) directly to our eyes.
Hence, the brightness control should do the opposite job as well.
In a phone screen, you need more luminosity in a brighter environment and less screen luminosity in a dark room. In a dark room, going zero brightness makes it impossible to see anything on the LCD/LED screen.
The Kindle device the opposite way: you don't need brightness at all in a bright environment! You could turn it zero. The screen reflects the environment light just as a real book page does. On the other hand, in a dark room you need some artificial light to read, again, just like a real book.
To sum up: auto brightness control should reduce brightness in clear environments and increase (not too much because it blinds you) in a dark room. Just the opposite way of the auto brightness control of a LCD/LED phone.
I can't understand why Amazon who created the e-ink technology haven't noticed such a mistake yet. Many users are complaining about the auto brightness feature, saying it doesn't work, but they didn't realize it is working, but the opposite way people expect. But you set up the auto brightness feature as you do in a Kindle Fire and smartphones.
At least Amazon should consider including an option to invert the way the auto brightness feature work. They'll see lots of people say: 'Wow! It finally worked well!'.
P.S. please forget any language mistakes I might've made. I'm not an english native speaker.
