X Neo Dark Mode

Hello.I bought a new X Neo but I can’t achieve the Dark Theme from the Settings > Display > Advanced > Device Theme.  The result stays the same in Light or Dark Theme.

Please advise.

Thank you in advance!

Hello, I’ve got your same problem.
I hope that there is a simple solution for this.

that setting doesn’t seem to work correctly.
What works on my X neo: setting to dark AND use a dark wallpaper (I’m actually using pure black).
