"Changing brightness will crash settings" did not issued on my device.
Changing language does, however, crash settings.
Also the battery seems to be draining faster than stock OS, for some reasons.
The number display format issues is still there I have no idea how to change it.
In messages, use dark theme setting is ignored.
I also after half day of usage noticed my phone keep unlocking in my pocket, I don't have any special unlock features enabled like home button or so, is this normal?
Later edit: Quick-toggle for brightness will not always work - I cannot reproduce, there was one time that ignored now works fine after many tries and flashes. Safe to remove.
