I would like to be able to take calls (via loudspeaker) on my phone whilst using GoogleMaps as my sat nav. The problem I have is that when I answer an incoming call the screen switches to the caller screen and therefore GoogleMaps can no longer be seen and used for navigation.
This is annoying for two reasons. I can't see the sat nav and the only way to bring GoogleMaps back is to touch my phone. Touching my phone whilst driving is illegal where I live. So I use buttons on my steering wheel to answer calls which is legal. However, unsurprisingly, there is no button to bring GoogleMaps back. Does anyone know a way of stopping my phone from automatically switching to the caller screen when I accept a phone call? I've been unable to find a solution
