A smartphone is not an exploratory device. Its tiny form factor and lack of keyboard input are forbidding. Even a lower-end unit is a relatively sealed package. I can get a command prompt on my 'droid unit via termux, but it's not going to show much, or easily integrate with the OS, for security reasons. The kicker is that, from a risk-management perspective, I don't want to jack around with my (non-cheap) 'droid unit and risk bricking or destabilizing it.
