Apparently, it is working on an app called "Linux on Galaxy" that will let users "run their preferred Linux distribution on their smartphones utilizing the same Linux kernel that powers the Android OS".
"Whenever they need to use a function that is not available on the smartphone OS, users can simply switch to the app and run any program they need to in a Linux OS environment", Samsung says.
The app allows multiple OSes to run on a device. Linux desktops will become available if users plug their phones into the DeX Station, the device that lets a Galaxy 8 run a Samsung-created desktop-like environment when connected to the DeX and an external monitor.
Samsung believes that developers will want to set up a fully functional development environment “with all the advantages of a desktop setting that is accessible anytime, anywhere”.
It seems to suggest an idea that that developers will “code using their mobile on-the-go and with Samsung DeX, and can continue the task on a larger display”.
Samsung describes it as “still a work in progress” and there is no indication when it will be available.
