I did the 2024.08.06 update, and no matter what I do the screen brightness slider is gone from my notification panel. It shows only when I drag down a second time to expand the quick panel a second time, then I can adjust the brightness.
I've rebooted the phone. I've restarted the launcher/home. I've turned "eye comfort shield" off and on again. I've turned dark mode off and on again. I've turned auto brightness off and on again.
I have "show brighness adjustment always" turned on , and I've turned it off, then on again. I've gone into adb and done:
a35x:/ $ settings put system pms_notification_panel_brightness_adjustment 0 a35x:/ $ settings put system pms_notification_panel_brightness_adjustment 1
Nothing seems to work, to get the screen brightness adjustment to show up.
Nobody ever wants to do a factory reset. At least with the backup available, it's pretty painless (except if you use Samsung Pay). Like I said, you could always wait for the next update. It's not like you can't adjust the brightness at all.
In case anyone should ever read this in the future, this is the command that fixed it (run the command, then reboot): ~$ adb shell a35x:/ $ pm install-existing com.samsung.android.mdx.quickboard Package com.samsung.android.mdx.quickboard installed for user: 0
