Thank u it fixed all the dark mode problems not just status barA solution has been given, page 14, by @Mikanoshi (Thanks to him):
It requires "root" access:
1) Install "Termux" app, on Google Play, and open it
2) Type: su
3) Type: settings put system smart_dark_enable 0
4) Done! You can type exit and exit again to cleanly close Termux
Warning: If you go in "Dark Mode" settings, you will need to set "settings put system smart_dark_enable 0" again.
EDIT: Created TWRP zip package to flash if you don't have root => TWRP_Dark_Mode_Status_Bar_Fix_v1.0.zip
