This video shows that Manjaro (Arch Linux) is working on Samsung Galaxy S7 in natif. No android only pure Linux. Touchscreen is working, wifi and USB mouse/Keyboard.

You can find ARM images of Manjaro on their website, https://manjaro.org/download/#ARM

For more information about how to run Linux on smartphone you can see Postmarket OS's wiki https://wiki.postmarketos.org/wiki/Main_Page

This is a demo on running Linux (Debian stretch) on Lumia 950 XL. For now, only touch and display are working. Hope more features will available soon.

Thanks:-
