This is very odd and strange!

On phantom 4 pro and phantom 4 advance downloads page, the firmware to download is exactly the same:

Question is: is the p4p firmware different from the pjantom 4 advance?!

If so, might this be the cause on so many problems?!

Best to all!

This is for the remote with the built in screen.

If the firmware is on a specific product page, it would be fine to upload. Of course, if you are concerned you can always update the firmware through the Assistant 2 software.
