@PINE64 "We actually considered something very similar ourselves in the future ..." Hopefully, the Pine64 LapDock will be similar to NexDock 2 with an optional touch screen.

Yes, above statements seem correct. The only way to provide data and display over one cable to Nexdock is displayport over USB-C, and it seems like Pinephone does not support this feature.

NexDock 2 and Ubuntu Touch

Will NexDock 2 work with a Nexus 5 running Ubuntu Touch?

As I understand it, NexDock 2 does not have present the kb/mouse over Bluetooth, so you would only be able to use it as a monitor for Nexus 4/5.

Will NexDock 2 work with the new Pinephone running Ubuntu Touch?

It will not work over the USB-C as the Pinephone as I understand will not have SlimPort (DisplayPort alt mode), but straight HDMI. You would need an adapter to split the video out to the HDMI port on the NexDock 2, and use the USB-C for the kb/touchpad and charging connection.

Are the above statements correct?

Will the Pinephone be compatible with NexDock 2?

@mariogrip UBports Nexus 5 phone has incorporated Anbox, and when a touch tablet is connected with a Slimport to HDMI adapter it is able to display Main Stage and Side Stage for multitasking:

I was able to locked/unlocked and load UBports on the Nexus 5 with the Magic-Device-Tool. However, it did not install Android [[7] Install Factory Image]. Nor did I find any relevant information in the UBports wiki.

Nevertheless, it was possible to re-install Android on Nexus 5 after consulting the following references that provided guidance:
