Question regarding screen dimming

[12wallstreet]

Hi Everyone,

So far I am really enjoying the S22 Ultra but one issue I have is keeping the "home screen" from not dimming when I have it charging on a charging stand. If an app is open screen remains bright while charging but not when I am on my home screen

I have developer mode on and set it to screen always on while charging, also, Adaptive brightness is set to off.

When I put the phone on the charging stand it remains bright for about 15-20 seconds and then it goes to what looks like half the brightness.

Any idea what setting I need to select to keep the screen bright constantly while charging?

Thanks
