== Workaround to fix "Global Dark Mode" ==
Preamble: If you rooted your phone, I advise you to install "Termux" app (on Google Play Store) and open it (at least once) before installing the patch.
(You will understand why if you read "INFO" messages from zip installation)
Download and install this zip in TWRP =>
TWRP_Dark_Mode_Fix_v1.4.1.zip
It will try to fix the status bar color when dark mode is enabled.
IMPORTANT: You will need to apply this workaround again if you disable the dark mode option!
EDIT: You may still need to disable some apps in "Individual apps" menu in 'Dark mode' settings if some texts/images are not correctly visible.
EDIT 2: For "Google" app, please install beta version of this app and change "Theme" option in app's settings to "System detection" or "Dark" to fix status bar color.
Enjoy!
EDIT 3: v1.4.1 = Auto-close Termux when using 'dmfix' command (if the fix is applied successfully).
