This is a two part problem. One you need a better input capabilities than what a normal touchscreen keyboard provides. For this there are only a few options that are mobile. Either whip out a blue tooth keyboard, which is hardly applicable if you're standing, or use a chording keyboard such as the twiddler[0]. The later take some time to learn, and are still somewhat awkward, in that you look like you're carrying a detonator device in your hand at all time. The second problem is that most mobile devices are walled gardens that don't allow you full access to your pocket computer's sensors and filesystem. This makes piping the output of one program into another (even say an editor, to email or a compiler) difficult, to say the least. In this case you really need to jailbreak your phone, or purchase an open option such as a PinePhone. [0](https://twiddler.tekgear.com/ https://twiddler.tekgear.com/)
