I used Motorola's version of DeX with my Razr Fold, and it's nearly replaced my laptop

Motorola’s Razr Fold includes Smart Connect software that provides a desktop-like interface similar to desktop modes. The phone can function as a trackpad for a connected keyboard and display, enabling window resizing, repositioning, stacking, and side-by-side layouts. A Bluetooth keyboard allows typing, and the phone’s touch input can move a cursor across the screen. The setup works with a portable monitor and smart glasses, offering a large workspace while on the go. Portable monitors require their own power, but some support passthrough charging so the phone can charge when connected. Using glasses can reduce the phone’s battery faster, making charging support useful.

"Motorola's Smart Connect software gives the Razr Fold a desktop interface similar to Samsung's Dex Mode. One way I've talked about working on the go is with and Samsung Galaxy's S26 Ultra and Dex mode. When you plug the glasses in, and enable Dex mode, you get a desktop-like windowed interface for your apps, similar to Windows or MacOS."

"Just like on a laptop, you can resize windows, move them around, stack them on top of each other, place them side-by-side, etc. Connect a Bluetooth keyboard to type, and you functionally have a laptop to work on. The ProtoArc XK01 keyboard I have has a built-in mouse, which is handy. You can also use the phone itself as a touchpad to move the mouse around the screen."

"This time around, I'm pairing the Motorola Razr Fold with a Logitech Keys 2 Go keyboard (which does not have a touchpad) and an Arzopa Z3FC 16-inch portable monitor. Pretty fun (and not practical) way to work. These XR glasses effectively replaced my dual monitors for work - and they're $170 off This has one big upside and one big downside."

"The downside is that you need power to get the monitor running. It can't run on the phone's power, which is probably a good thing since it would drain the battery pretty quickly. The good news is that the monitor supports passthrough charging. When you plug in the monitor and connect the phone, the phone charges. When you connect XREAL glasses, the phone can discharge pretty quickly, so this is a nice bonus."
