I would like to know if it is possible to change the screen if the companion is lost.
I need to send http messages, so i need to connect my phone to other internet, and when I do, I can still do all the normal things except change the screen, which is only possible when I'm connected to the companion.
You will need to compile your app for testing if using a different network to that of the companion. Or look to see how you can send these http messages without needing to switch networks.
