It's written in the android settings. I'm not sure how it's working because it have to points where it set. One is android settings. Other is in home-screen settings.
Seems it works more or less correctly. But i wish there were more then 2 levels of brightness. Lowest level for night. Middle level for evening/morning and highest level for sunny day.
Not sure how it could be handled... But i wish it could be automated.
For example. As we have gps based sunset, we could calculate sun position above ground. And set the highest level when the sun is higher the 20 degrees for example.
Other option is read from can from twilight sensors. But i don't think it's is universal level... So gps/sun position is more realistic.
Yep, another option is external USB light sensor, so anyone could buy it and install.
