Quick question,
Is there any way of turning flight mode on or off for android devices from within unity?
Google search comes up with nothing except “have airplane mode turned off” or what airplane mode is.
Would I have to write an external plugin?
Airplane mode is just a short way to disable a whole bunch of stuff, like the Mobile, Bluetooth, and Wifi (your phone may do others). On my HTC Incredible 2 I can set Airplane mode and then enable WiFi, but if you can’t do that, rather than just going to Airplane mode, go to your settings and turn off “Mobile” - that will disable both phone and Data roaming.
