Haha I didn't even notice it. But you made me realize how incredibly inconsistent the feedback "button" is in the used-to-be-AOSP apps

• Clock has it in the three dot menu on the main screen AND in the three dot menu in settings
• Phone only has it in the main three dot menu, but it's completely missing from settings (oh and the Settings->Accessibility screen ignores Material You colors for some reason)
• Contacts has a decoy three dots menu that only contains Select and Select all buttons, the feedback option is hiding in the account switcher (and is once again missing from settings)
• Messages once again hides the feedback button in the account switcher, but it doesn't have a three dots menu so it makes sense. No feedback in settings
• Calculator has it in the three dots menu and doesn't have any further settings
• and finally, Camera: tap the quick settings button, tap More settings, scroll to the bottom and boom, the feedback button.

I know this is completely useless information, but I was curious and thought it would be a shame to just forget my findings 5 minutes later
