Even if you have Android 16 it's not guaranteed the terminal works. It's disabled by Samsung on my Galaxy A55 for some reason. Maybe the hardware doesn't support the feature.
I'm just as baffled. I went to the comments to better understand but I still don't get it.
I've coded on my phone on several occasions. If you use Android, you don't even need a server or a home computer since Termux works really well as it is. It can run node.js and a bunch of other development tools easily. Or you can just ssh into a server with a development environment and do your stuff their (AI or not).
I pretty much already use my Steam Deck as my main Desktop computer at home (I have a laptop for work). If I wanted to upgrade, this would be a no-brainer.
