The decision leaves users in a tough spot. This not only gave Linux fans a way to run their preferred computing platform from their phone, it was the only option that provided a full-fledged desktop OS (in this case, Ubuntu Linux). If you use Android 10, you’ll have to revert to the considerably more limited DeX-optimized Android interface. While that should work for people who just want a larger canvas for their Android apps, it won’t help if you were using Linux as a productivity tool.

Samsung is still committed to DeX, and recently enabled its desktop-style space on Macs and Windows PCs. However, it’s clear that the dreams of fully replacing a PC with your Galaxy phone will have to wait, at least for now.
