Related crash with iOS. I say related, because it's not reporting setBrightness as the crash, but _userInfoForFileAndLine, after setBrightness. If interested:

Significantly, this one tells me: 94% In background.

Please let me know if I can provide any additional details to help get this fixed. Thank you!

Hi there. Just adding more details. By a stroke of pure luck, I produced this on Android Pixel 6XL with Android 14. My actions were:

uninstall the app
fresh install the app
drag to home from drawer
launch the app from home screen
app crashed

But it's not every time, and I have tried 10x in a row to reproduce without success.

Device brightness is about 33%. Extra dim disabled. Bluetooth disabled. Internet and Location services on. Network was unthrottled. No instant permissions prompts for this app.

Hey! I'm experiencing the same issue on various types of devices and Android versions. Any updates on this?
