Techbiz.id – Samsung continues to demonstrate its ambition in the world of foldable devices with the Galaxy Z TriFold. When folded, this phone remains compact like a standard smartphone, featuring a 6.5-inch cover screen. Though, when fully opened, the galaxy Z TriFold transforms into a 10-inch wide-screen device, delivering a tablet-like visual experience.
The benefits of this large screen are further enhanced by independent Samsung DeX support. Users can simply connect a mouse and keyboard, and the Galaxy Z TriFold instantly enters desktop mode. This allows users to open multiple applications concurrently, adjust window layouts, and perform productivity tasks without needing additional devices.

Interestingly, the Galaxy Z TriFold’s innovation extends beyond its triple-folding design. Samsung also equips this device with the ability to function as an additional monitor for a Windows PC.
According to a report from Android Authority (December 13, 2025), samsung confirmed that the Galaxy Z trifold is their first phone to directly support standalone DeX and Extended Mode as its launch in December 2025. This feature enables the phone’s display to be projected onto an external screen, similar to the functionality available on the latest Galaxy Tab series.
Samsung doesn’t explicitly state that a PC screen can be expanded to the trifold, but this capability can still be utilized through the Second Screen feature.
