The thing with phones is that they are tricky to work with, because their systems is quite closed. I have in mind a couple of strategies, but please take into consideration I am not expert in mobile development, so maybe there is a solution I don't know about. I am just brainstorming, please take what seems better

>jailbreak an old phone, install Termux on it and try to program something that could communicate under TCP/IP
>use an android emulator like Nox and research if is possible to load the virtual image into a mini pc computer

What I see is that it is necessary to build a customized user interface. Read about Raylib, it supports web development.
