iPhone 8 Plus with iOS 11.0.2 issues.
I have an iPhone 8 Plus, Space Gray, 64 GB. I upgraded to iOS 11.0.2 and soon after noticed that my brightness was not automatically adjusting to my lighting conditions.
I did some poking around the settings and found that I no longer have the TrueTone toggle under Settings->Display &Brightness.
Also not present in the control center:
I also do not have the auto-brightness toggle under Settings->General->Accessibility->Display Accommodations (although I do see the tool tip text for auto-brightness).
It's like the auto-brightness and TrueTone features are not present on my device any more.
I spoke with Apple support and the issue persists even after a clean iOS install from iTunes. It's been escalated to engineering and I am waiting on feedback.
I haven't tried downloading and installing 11.0 or 11.0.1 yet. I may try that when I have time.
Also, my "Hey Siri" functionality is not working. Regardless of whether or not the screen is on or off.
