If I understand your first point correctly, then I have great news. I guess my wording could have been more clear, but PocketBook devices do NOT run Android.
As for the second, if that is a requirement then at least the Era doesn't have an ambient light sensor. I don't have any issue without it because I just have the front light off entirely by default since it is e-ink. Obviously if I need to use it in the dark I turn it on, but that is easy without having to navigate a screen I can't see since you can configure a hardware shortcut to toggle the front light (it is set to long press on the home button by default). While it does support automatic screen brightness and temperature (individually toggled), these are driven by a schedule based on the set timezones.
