I've never used a Samsung phone, but I think their DeX environment might allow you to do the same things that the "terminal" app supplies.
If you can't get either of the above to work, give Termux a try. It's not full gnu/Linux, but it's pretty close.
The first is Termux, which provides a gnu userspace atop the Android kernel. This app is pretty old, and well-tested. There is an active and helpful Termux community. But it has some downsides: 1) The version of Termux in the Google Play Store is not the preferred and maintained version, although the Play Store version does work. The preferred version is in F-Droid, but the future of F-Droid itself is uncertain in the light of recent Google policy decisions. 2) Termux does not have access to directories such as /proc, /sys etc, which prevents some gnu/Linux utilities from working and 3) The Termux filesystem layout is very non-standard, so unless a program has been packaged explicitly for Termux, installation will probably be messy. I was able to get most, but not all of the Python packages I use frequently, to run within Termux. I could not get astropy to work, for example. Termux has nice usability features like pinch-to-zoom to change the font size. Termux requests a wakelock, and if you grant the wakelock then the OS will not throttle the app when your phone is locked.
The other option is the relatively recently added "terminal" app. terminal runs a plain-vanilla Debian Linux OS within a VM. Its file system is laid out exactly as you would expect, so if you want to get iPython and lots of libraries, you can just run the Anaconda Python installation script, and it will run unmodified with no errors. Nice! You can also install other nice desktop-style apps like VeraCrypt. There are a few downsides: 1) The OS will throttle the app, and occasionally kill the app, when the app is not actively being used interactively. 2) I have found no way to change the tiny font. 3) It's a Google app, so it might disappear for no good reason, as so many Google products do.
Both of these options work especially nicely on a foldable phone, because then the tiny phone keyboard is much less of an issue. A foldable phone plus the terminal app really is a pocket Linux computer.
What's going on is AI fatigue. We see it everywhere, we use it all the time. It's becoming generic and annoying and we're getting bored of it EVEN though the accomplishment is through the fucking roof.
If elon musk makes interstellar car that can reach the nearest star in 1 second and priced it at 1k, I guarantee within a year people will be bored of it and finding some angle to criticize it.
So what happens is we get fatigued, and then we have such negative emotions about it that we can't possibly classify it as the same thing as human intelligence. We magnify the flaws and until it takes up all the space and we demand a redefinition of what agi is because it doesn't "feel" right.
We already had a definition of AGI. We hit it. We moved the goal posts because we weren't satisfied. This cycle is endless. The definition of AGI will always be changing.
Take LLMs as they exist now and only allow 10% of the population to access it. Then the opposite effect will happen. The good parts will be over magnified and the bad parts will be acknowledged and then subsequently dismissed.
Think about it. All the AI slop we see on social media are freaking masterpieces works of art produced in minutes what most humans can't even hope to come close to. Yet we're annoyed and unimpressed by them. That's how it's always going to go down.
Americans were glued to their seats watching Apollo 11 land. Most were back to watching I Dream of Jeanie reruns when Apollo 17 touched down.
