I would like to use my phone (LG K8) as a monitor for my raspberry pi where network connections are not available. How is it possible?

I shall also mention that I do have the official touchscreen but it is too large for my purposes and VNC did not work as neither of the devices will have access to any network where this will be used.


Make the phone a hotspot. Connect the R-Pi to it. Use 'Fing' (get it from your favourite app store) on the phone to scan and detect the R-Pi IP address and use VNC to connect. That may work.

  • I have attempted to use this method but my phone is unable to find my RPi. – Lucas O'connor Oct 4 '17 at 20:41
  • Can you make the R-Pi find and connect to the hotspot SSID? – Andy Anderson Oct 4 '17 at 20:46
  • It can do that but my phone becomes stuck attempting to connect. – Lucas O'connor Oct 4 '17 at 20:52
  • Using the RealVNC app on the phone? VNC enabled on the R-Pi? – Andy Anderson Oct 4 '17 at 20:58

Try VNC, remote screen over IP.

  • I have already attempted this but I could only get it to work over a network connection. – Lucas O'connor Oct 4 '17 at 18:43
  • Yes thats the only way you can use a phone as a display. – MatsK Oct 4 '17 at 19:37
  • Is there no screen mirroring app that will work? – Lucas O'connor Oct 4 '17 at 19:55
  • What you are asking for is, "How can I turn a output into a input". – MatsK Oct 4 '17 at 20:02
