I teied using termux as a “linux” on androis before, but tbh I dont quite see the use case.
Termux as it is is great for ssh-ing into my headless server and executing commands. But everything else i do on my phone / tablet is something that a phone/tablet can already do, so idk what to do with (a bit clunky) x intterface. I tried programming via termux on my tablet, but that wasnt that great either since for text files a proper vim setup would have worked as an ide for me, and graphics accelerated stuff (ie opengl vulkan etc) are (ofc) not supported with this termux linux.
