The Galaxy Z Flip 6 has been discovered to support the new Samsung DeX instead of the classic one.
New DeX is an updated version of the desktop mode experience that Samsung introduced in the One UI 6.0 tablet update.
In contrast, the Galaxy Z Fold 6 still supports the classic DeX experience.
Many people wish they could use their Android phone as a portable PC, but Google’s base operating system sadly still lacks a proper desktop UI and many desktop windowing features. Fortunately, some Android OEMs have taken it upon themselves to add a desktop mode of their own. Samsung DeX in One UI is one of the more popular and robust desktop mode phone experiences, but it’s not available on every Galaxy device. We initially thought that the Galaxy Z Flip 6 was missing Samsung DeX support, but it turns out we were wrong, at least partially. See, the Z Flip 6 does support DeX, but not the version most people are familiar with.
DeX is available on select Samsung phones and tablets, but it can only be enabled on phones hooked to an external display. Tablets, meanwhile, can use the DeX interface on-device, giving them a powerful desktop mode experience on the go. In One UI 5.1.1 and older, the on-device DeX interface on Samsung tablets matched the external DeX interface on Samsung phones.
