Not sure where you got that idea but it doesn't sound right.
The Samsung A15 was released at the end of 2023, which makes it newer than the A53 mentioned in post #8.
The Phantom 4 came out in early 2016.
The A15 should comfortably have more than enough processing power to run the Go 4 app.
Either controller is likely to be just as good as the other.
The controller with the built-in screen has some other limitations.
But ... you mentioned that you are getting a Phantom 4 standard rather than a
Phantom 4 pro.
Although post #8 said:
The 300E remote has built-in screen and will operate all the P4 models. (Standard, Advanced, and Pro).
That's not quite true.
The
Phantom 4 pro and P4 pro V2.0 have different transmission systems and their controllers are not interchangeable.
And the Phantom 4 and its controller only used 2.400 GHz to 2.483 GHz while the P4 pro used 2.400 - 2.483 GHz and 5.725 - 5.825 GH.
I haven't tried swapping their controllers, so I'm not sure if post #8 is correct or not, but I would be cautious about relying on it.
Are you certain that you are getting the Phantom 4 standard?
Also .. if you are a new flyer, be aware that there are flight restrictions in the vicinity of Sydney Airport.
