Display timeout

My A02s on occasion, changes by itself. I usually have it on 30min. It changes to 20sec by itself whenever it feels like it. Is there a way to stop this annoyance?

You could try a factory reset

I tried that months ago but that did not work. I am thinking the issue is in the OS 11.

I've used this before and worked well....

Thanks. I will try it.

Odd coincidence I ran into a similar problem with my OnePlus when it was running 11. I'd set the screen to go off at 5 minutes and that worked out well for a bit. Then a few hours later or even a few days later, the screen would go asleep after 15 seconds. I'd set it back to 5 minutes, and the bizarre cycle would repeat. Turns out there's an obscure option buried pretty deep in the Settings menu that I needed to just disable so my preference for 5 minutes would stay that way. It was in the Settings >> Battery >> Power saving mode >> Default optimizations menu and the option was 'Change auto screen-off time to 15 seconds'.
There's likely to be a similar option in your Samsung but in a different menu hierarchy and/or using slightly different naming. Use the Search feature at the top when you first open the Settings menu, that can save time trying to get to some lessor options buried really deep in a contextual menu inside another contextual menu.

Mine says power saving mode which is off. Then there is adaptive battery which limits battery usage for apps that you don't use much. Nothing about default optimizations.
