I often find myself issuing a quick fix or something by pulling out my phone, opening Termux, remoting into a server with SSH, and editing a text file with something like Nano. That is, for all intents and purposes, coding. And it works well enough for that. I am generally familiar with the project via my time with it on desktop, so I know what small change I need to make and can do so quickly with just about any text editor. And even if I want to create an entire small script from scratch via my phone, I generally have the whole process mapped out in my head and just need to use the phone to type it out.

But anything that requires a lot of typing or screen space is generally better to do on desktop. Even though something could technically be achieved on a 6” screen using an onscreen keyboard, many things are simply more streamlined and effortless using multiple windows and a physical keyboard.
