# To avoid get the quick settings and the notifications panel split horizontally on landscape phones run:

adb shell cmd statusbar flag lockscreen.enable_landscape off

# or

adb shell am broadcast -a com.android.systemui.action.SET_FLAG --es name 'lockscreen.enable_landscape' --ez value 0

# then turn off the screen and turn on again, no need to restart the phone.

/**
 * Concrete implementation of the a Flag manager that returns default values for debug builds
 * <p>
 * Flags can be set (or unset) via the following adb command:
 * <p>
 * adb shell cmd statusbar flag <id> <on|off|toggle|erase>
 * <p>
 * Alternatively, you can change flags via a broadcast intent:
 * <p>
 * adb shell am broadcast -a com.android.systemui.action.SET_FLAG --ei id <id> [--ez value <0|1>]
 * <p>
 * To restore a flag back to its default, leave the `--ez value <0|1>` off of the command.

# Deprecated: If you have root, you can run the commands below to avoid restarting the phone.

# adb root
# adb shell killall com.android.systemui



# Better would be some config option to switch that behaviour as asked in.
