If you've been using Linux on DeX (aka Linux on Galaxy) to turn your Samsung phone into a PC, you'll need to make a change of plans. Samsung is warning users that it's shutting down the Linux on DeX beta program, and that its Android 10 update won't support using the open source OS as a desktop environment. The company didn't explain why it was shutting things down, but it did note that the Android 10 beta is already going without the Linux option.
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.
