Hi! I tried to run auto brightness settings tuned for Nokia N900 on Droid 4, and results were not nice.
So I tried matching brightness between Nokia N900 and Droid 4, and I have a reason: Brightness 1 on n900 corresponds to brightness _50_ on droid 4. | n900 | d4 | | 1 | 50 | | 2 | 70 | | 6 | 100 | | 8 | 120 | | 20 | 130 | | 30 | 140 | | 40 | 150 | | 100 | 180 | | 128 | 190 | | 150 | 200 | | 200 | 210 | | 255 | 220 | Values are very approximate, I did manually. (Light sensors are funny, Nokia seems to have calibscale on intensity input, which should be unitless, but not on illumination input, which should be in lux. And I'm not sure... is value_in_lux = illumination_input / illumination_scale?) I'll get some sleep now, if you know what is going on there, let me know...
