Do this while driving in bright light.
- Have music playing.
- Swipe up from bottom to show Bluetooth etc panel.
- Swipe to swap to sound but accidentally move brightness to nothing.
Phone is useless. Display is too dim to see in daylight. Reboot won’t help. Siri won’t adjust brightness.
Need to find dark bathroom at gas station to enter passcode and adjust.
I think I might also have had some iOS “night shift” state confusion and a miscalibrated auto-brightness that made things worse.
Would be good to have a fix of some kind…
