I have two phones. I would like to have all my files on one, but be able to have two open at once.

Can I set up the second phone such that it extends / adds a second screen to my phone?

I do not want to use BTSync or similar (the second phone has limited storage).

  • I don't think it is supported. Maybe third party apps + root.

  • @SarpSTA Well yes, I would expect some apps involved. Both phones are rooted.

    To be clear, you want to use another android device as a second monitor for a primary android device? Do you only want screen extension, or also mirroring?

  • @jiggunjer I can easily do monitoring with Teamviewer. I'd like to extend the screen, and maybe have 2 apps visible at once (via XPosed window positioning I expect).

  • I wouldn't use TeamViewer for simple mirroring. It is more for remote control. So yes, you want an extended monitor.

Clipboard sharing + cloud drive. With those two you can do a lot with minimum setup.

For PC like experience you may share your peripherals. Not trivial, though.

The biggest challenge is to sync the clipboard in a safe way. Most solutions are through WiFi router or internet and making a easy Bluetooth connection is a challenge.
