According to Engadget, Samsung's DeX mode can now launch directly on the Galaxy Z Fold 8's inner screen. Until now, DeX was mainly associated with plugging a Galaxy device into a monitor or TV to create a PC-like experience. The new trick removes that external-display requirement, turning the foldable's large internal panel into a desktop-style workspace.
Launching DeX on the phone itself is significant because it blends the convenience of a handheld device with the multitasking advantages of a desktop interface. Business users who want a laptop-like experience without carrying extra hardware could find this particularly useful. The fact that it is described as a trick suggests the capability may not be widely known or prominently advertised.
Since there is only one source covering this, there are no conflicting reports to compare. The main takeaway is straightforward: Samsung appears to be closing the gap between its phone interface and a true desktop environment, at least on its latest foldable.
