I agree wholeheartedly.Litchi is very good if you need it for waypoint flying but I wouldn't recommend buying it just to replace DJI Go.
Why?and to get back to OP's original question... this happened to me once after traveling 60 miles to a waterfall - the ap was looking for an update... i tried using my cell phone as a mobile hot spot, but it was taking forever to download... I gave up and came home.
Why?
If your Phantom was flying fine last week with last week's firmware, it's still going to fly just as well this week on the firmware that it used last week.
If you looked at what was in the firmware update, it's almost certainly something trivial or even irrelevant to you and your flying.
Later on reflection I think this might have been it... but as I said in post above... I couldn't even get into the flight screen (camera) - it was locked on the splash screen saying need internet connection... In the past when I didn't upgrade a battery it would appear on my flight checklist as an anomaly which I would then fix... thx for your thoughts...Hi PunaPhantom,
Do you have several P4 batteries?
I got an idea why GO app would try to update without internet connection.
User swapped to another P4 battery requiring firmware update and in that case no internet connection is needed to detect upgrade is needed.
Just an idea..
