Please and thank you
It does work, I have been using it for a long time now in context of my interest of using a phone as a PC.

Thing is that with just termux, you get just the android/termux environment.
There is a way to get more familiar Linux environments running on your phone by using proot from within termux.

For example, using that you can install ARM version of Manjaro, which is basically the same thing that you would run on Raspberry Pi.
But everything in there runs a bit slower, because Proot is some layer that takes up a bit of performance.
Benefit of that is that you can run some Linux software that is not found within Termux packages, but is available in the repositories of other distros. Libreoffice is one such example.
