I where just thinking and are far ahead now of everything.
But i see this as a fixt not changeable function that need to be implemented on monile devices. The problem with mobile devices is that people use it wrong
So my suggestion when high fidelity is going to make apps. That the software detect when speakerphone is enabled annd stop sending voice. sounds are fine.
Because VR on mobile can have a very big impact on privacy. Especially when you see how bad people are using it. on street, in shopping mall, etc. And the other people in VR dont know where the mobile user is.
There must be better way then i describe above. but right now it’s just to be csrefull on how it get implemented on mobile.
