Recalibrate error on iPhone 7 only

[corky]

Hi guys newbie here
I have the following error on my iPhone 7 running iOS 10 and downloaded dji go 4 fresh from the App Store
Never had the error on my Samsung j5 or Samsung tablet and still don’t if I use them again only when I put the iPhone on to use, any ideas ?

Do you see that error when you power up your Phantom outside during the day?
