I'm looking at buying a P3P at the moment ive got an iPhone 4 do I need to upgrade this to run with the p3p and if so what do you out there suggest (phone) and system android or iPhone?thankyou for any help
The iPhone 4 will not work since the screen is too small to display DJI GO (it'll be cut off on the right side). You can find a list of recommended and commonly used phones and tablets here.
