    Does anyone encounter after updating to iOS12.0.1 the auto brightness features does not adjust the brightness smoothly and consistently? E.g. when I am in a dark room the iPhone screen brightness is still set at just below half of brightness bar even when I turn on and off the screen.

    I could never get auto brightness to work the way I think it should on my X or my current XS Max. I'll go out into very bright sunlight and it would dim itself. In the car I would be using navigation during the day and it lowers the brightness.

    The worst thing is it would lower to what looks like 30% but the setting shows it's maxed out and wouldn't change until the slider was moved down until around 30%. Then when I would slide the setting back up, it would still max out at what appears is 30% even though it's set to the highest setting. I got tired of messing with it and just turned it off.

    Calibrate it properly. Be in a pitch black area if possible, have auto brightness on, then manually slide it the brightness you want in that dark scenario (or all the way down). Same for max brightness in the brightest areas.

    It's an issue for me on my Xs. I'm guessing it will be fixed in 12.1.

    When issues like this happens, i like to go into Settings >> General >> Accessibility >> Display Accommodations, slide "Auto-Brightness" to OFF, then turn it back on again..

    Software Updates happen to sometimes break things ? *shrugs*
