I just bought a used Phantom 3 Pro and I am running into an issue I am hoping someone can suggest a solution for.  I linked the controller to the drone just fine, and the controller communicates with the drone fine, shows the green connection light on the controller and controls the drone's motors as expected.  I updated the firmware in the controller.  When I run the DJI Go app on my iphone, it opens initially and then always closes shortly after.  If I disconnect the control unit from the drone (I power down the drone, the connection LED on controller shows red) the app will stay open.  But as soon as I power up the drone (connecting it to Control Unit) then the app crashes.  I am running an iPhone 6Plus, iOS version 12.1.2, capacity 64gb with 10.72gb available.  Any ideas?  Has anyone else experienced similar issues with the DJI Go app (not DJI Go 4) on iOS?

thanks!

Hi, sorry for the inconvenience caused. Can you please try to reboot your iPhone by pressing and holding the side button and either volume button until the slider appears. Drag the slider to turn your device completely off. After your device turns off, press and hold the Side button again until you see the Apple logo. You can also try to uninstall and reinstall DJI Go app. If the issue persists, please let us know. Thank you.

First thing I would do it uninstall the app and reinstall.

I tried that, no luck.  I also downloaded the DJI Go app to an ipad, connected that to the controller and had the same problem.  I verified the cable is functional by connecting the iPhone to my laptop - they communicate over the cable fine, iTunes comes up fine.  

There is a new version of iOS - 12.1.3 just came out, I will try upgrading the phone and see if that makes any difference.  Is it possible that no one is using iPhones/iPads with Phantom 3's anymore?  I wonder if DJI is no longer maintaining the app for new iOS releases?  Seems pretty farfetched, but maybe i should get an Android device and try that?

I am upgrading the firmware in the drone, maybe it is out of date.  I just bought this drone used, so maybe that needs to be done.  Applying firmware update now per recording on support site, we will see how that turns out.

I ran thru the drone firmware upgrade, the log said no update was needed, version in drone matched version of file.  I updated the iOS device to 12.1.3, retried and the DJI Go app is now stable, no crash!  Not sure if it was the iOS version or the messing with the firmware that solved the problem, but I am all set now!

Sometimes you never know what happened, or what fixed it........quirks.

Hi Dnedzel, I'm glad that the issue has been resolved. If you need further assistance, please feel free to contact us. Thanks for choosing DJI!

What is with the 12.1.4 ? That iOS version came out last week.

Hi, if uninstalling the app is not useful, it may be that there is something wrong with your iPhone, which leads to the problem. Faced with this case, you can try restarting or force restarting your device. Or you are able to make use of a repairing tool like Joyoshare UltFix if you do not want to lose data during the process. Hope this can work you out!

Hey Dnedzel, particularly I like updating my drone in the desktop app "Assistant". You can export and download de "Black Box"of the drone, check and update the aircraft, restore factory and much more. It's just a suggestion. I'm glad you solved the issue.

Hello,
First you need to know figure out the reasons that cause the problem. Something wrong with DJI Go app, the iOS system, or the hardware error? Try some solutions like reinstall the app, reboot the device, force restart your iPhone, reset the settings, factory reset your device, etc. But you must be aware that resetting your iPhone to the factory settings will cause the data loss. Please make sure you have backed up your data before using any of the methods. After trying all the tips but still failed, maybe you can try a professional iOS system recovery from Tuneskit, which will help you solve most app crashing problems on iOS. Hope your problem is fixed.

I have also faced the same problem and wite a solution on my Tech Blog

Hello
I haven’t used my Phantom Professional drone for about 3 years. All seems up and running. Problem is when I connect the controller to my iPhone 13 Pro Max the app comes on, goes to ‘Aircraft Status’ and immediately crashes off! What’s going on? I tried reinstalling the App I tied hard restart on my iPhone but it is still crashing.
