A Samsung Galaxy S26 Ultra can handle practical coding tasks in a Termux-and-DeX setup: Oluwaniyi Raji reported using Git, SSH, Python and Node.js scripts, and browser-based code editing during a one-day test. He also found that longer compilations slowed as the phone heated up, and Docker did not run directly in his stock-phone setup. Raji’s account for Android Police was published October 12, 2026.
That makes the setup a plausible fit for repository work, scripting and remote server tasks. It is a narrower answer than a general laptop-replacement verdict: the reported results describe Raji’s workload, not a controlled comparison.
What coding worked on the Galaxy S26 Ultra?
Raji used Termux for development tools and Samsung DeX to work with an external monitor, Bluetooth keyboard and mouse. He reported cloning, editing and pushing Git changes; connecting to a server over SSH; running deployment scripts and monitoring logs; and running Python and Node.js scripts. Package installations also completed in his test.
For editing, he installed code-server through the Termux User Repository and opened its VS Code-like interface in Chrome. The setup took about 10 minutes, according to his account.
| Development task | Reported result | Practical boundary |
| Git changes | Cloning a small repository, editing files and pushing commits worked. | The account does not characterize the repository’s complexity. |
| Remote server work | SSH connections, deployment scripts and log monitoring worked. | These are the tasks in the reported workflow, not a compatibility guarantee for every server environment. |
| Scripting and packages | Python and Node.js scripts ran, and package installations completed. | The account does not provide benchmark results for these workloads. |
| Browser-based editing | code-server opened in Chrome with a VS Code-like interface. | Many server-side extensions were unavailable because code-server treated Android as unsupported. |
| Longer compilations and Docker | Longer builds slowed as the phone heated; Docker did not run directly in the tested setup. | The Docker finding applies to Raji’s stock-phone configuration. |
Which DeX connection works with an external display?
Samsung lists the Galaxy S26 series as supporting DeX on compatible external displays over cable/HDMI and wirelessly. Its support guide also describes using a USB-C-to-HDMI adapter. A monitor or TV is the relevant route for this desktop-style workspace. Samsung’s DeX guidance
DeX for PC is a different mode: Samsung says it is unsupported on Galaxy devices released with or updated to One UI 7 or later, including the S26 series. That restriction does not apply to connecting the phone directly to an external display.
Why Termux differs from desktop Linux
Termux provides a command-line environment and packages for Android, but its programs normally run on Android’s Linux-based host kernel and use Android’s bionic C library. Conventional desktop Linux distributions typically use glibc. Programs built for those systems may therefore need patches to work in Termux, according to the Termux project’s execution-environment documentation.
The project also documents optional proot and QEMU emulation without root. These are separate approaches from running Termux programs natively on Android, and they do not make the stock Termux environment identical to a desktop Linux installation.
