Android 11 brought the new power menu, to quickly change and use payment cards and to have useful quick toggles for smart home devices. Samsung should 100% add this feature and I think it's one many will want as well, as it got high praise from Google Pixel users
They could integrate smart things into the power menu. I really think they need to start embracing Google services more tho. like everything Google does, Samsung has to add a version into their phones.
