Lock screen display timeout

[Tapio]

Hi, something very basic, I always ignored the problem...

Setup:
Locus Map 4 operating in the locked screen. If I turn my Smartphone on via on/off button (so now it is still locked and Locus Map is up front), screen dims after 5 seconds without action and turns off after 8 seconds.

This is on a Huawei Mate 20 X.

I think Locus could keep my screen alive - Poweramp music player, also in lock screen, keeps the screen on.

Thoughts?

We're still in Systems lock screen.
I made an observation. If I use "Screen lock auto" (the Locus swipe/lock machanism) the screen stays on all the time.

Now after I unlock Locus, swiping the "Drag to unlock" bar (we're still in Androids lock screen) the short display timeout applies again!

In my relevant presets I had "Always screen on=Disabled"
