I have got my P4 two days ago.  But I can't find any capable apps from the App Store.  I don't think it is reasonable.

The P4 will use the DJI GO app which has not yet been updated to run the P4.  The "official" release of the P4 is the 15th, so it's not really fair to fault DJI for not yet supporting a product that you really shouldn't even have yet.  There is a workaround in the GO app, but I am uncomfortable in posting it, because there are reports that it forever names your Phantom "Tomato", and I am not sure if there are other adverse effects of the workaround.

It's not unreasonable, the official release is March 15th so I just a few days you'll be flying!!

Remember last year?  It was a week AFTER the release before P3 owners had the iOS app.

Thanks ALL

The DJI launch date is March 15th so the will be available then.
If it becomes available earlier, you will see it available in the IOS and Android store.
