With my Mavic almost here, I just wondered if I should uninstall the Go app on my device, the one I used with my P3S, before I install the Go 4?
As always, thanks a bunch.

It will load both no problem.  

No need to. just update to the latest version when you receive the mavic and welcome to the club1

Thanks for the information.  Although I won't receive the Mavic until Monday, I went ahead and downloaded the app to my 9.7" Samsung Tab S2.  I was happily surprised that an app (Rotation Control) lets me keep portrait orientation for the Go 4.  
I want to use the tablet but don't want to attach anything to the remote.  The tablet will fit the remote head first, I hope.  
We'll see.  
Rather than having the remote hold the tablet, I want the tablet to basically hold the remote.  
Does anyone know how much the remote weighs?
