BigJapan somewhere we do not understand each other. And we are marking time in the same place, we are talking about the same thing, but the dialogue is still in dispute mode. Let's try without multi-quoting in question-answer mode. So, the “problem” is as follows: you think that auto-brightness should be turned on and off regularly. I offer you this simple exercise:
1. Turn on auto-brightness in a lit room. Remember the position of the slider
2. Enter the dark room. Fix that the auto-brightness has worked and the slider has shifted to the left.
3. Adjust the position of the slider manually, making the brightness, for example, even lower.
4. Go out into the lighted room again. Note that the auto-brightness (again) has worked, the screen has become brighter.
5. Again (yes, yes) exit to the dark room. Note that this time the auto-brightness worked, but it reduced the brightness to the threshold you set in step 3.
Convenient, isn't it? And now
one simple question : why a function that works properly, moreover, it is possible to make adjustments to its work (and it works too) needs to be permanently enabled / disabled? If it is even simpler - what cases that are unattainable with the function turned on, do you reach with it turned off? And I will try to understand you
You can not read below, the rest
Not really understand what four levels of nesting are we talking about? Settings ->Screen and brightness. Everything. At this level (I would say at the first, because in the settings themselves, except for airplane mode, no settings and changes are made. This is just a menu.)
