Our FC40s dont really have any info about the phantoms status etc via the App from DJI.
I found a cool little free app called "GPS Status" that is avail for iPhone and Android that precisly tells you how many Satalittes there are and the signal strength.
I neat way to get avail Sat info prior to flying. When our FCs blinks green slowly it means we have 6 or more Sat...but how many Sats are avail in the area you're about to fly in?
This little App tells you.
I just thought this was cool and might help.
