Debugging on physical device does not replace app

I am trying to deploy a Xamarin.Forms Android application to a physical device for debugging.

If I deploy the application to my emulator, make changes and then redeploy the application restarts with my changes visible.

If I deploy the application to a physical device, I have to delete the installed app from the device before the updated application can be seen running on the device.

Is there some way to ensure the application on my physical device is updated so I see the most recent version every time I debug?

Thanks,
Lyall
