Has anybody experience with this problem?

Hello there. We apologize if you're having some issues with your drone. Did you check if the firmware was successfully finished? Can you describe to me how's the LED indicator of the aircraft and remote behaving? Did you try to reinstall the app?

Can you kindly take a screenshot of what you're seeing in your app?

If rear lights are flashing green, you're good to go.

And no sataliet

That does not look like the ideal place to start up the drone. Clearly a lot of tree's around, is there cover/roof above that terrace (it look like).
Has you tried starting it up out in the open with no obstacles around?

I think you don't really answer my questions, so i'll add another, what the difference on those two P4's? any modifications, added skins or other stuff?
