Not everything being sold as the R36s is able to use ArkOS (although I think there’s been progress on getting the other ones to use that OS), more deets here. Also, not every micro SD card works in that second slot, but yeah, just get a Samsung Evo Plus (I’m running dual Microcenter cards, don’t do this lol). There is a huge enthusiast community doing cool things with these devices, there’s a bit of tinkering to get them set up but it’s easy enough.

Alpaca, got anything set up through PortMaster yet? I’ve been meaning to get Stardew Valley and Half-Life on there.
