    Take a look at the video below.



    Needless to say, flying with so much video feed lag is very, very dangerous. Also, after the latest firmware update I haven't been able to get any flight without crashing my iPhone.

    I tried with another iPhone 6 and the same thing happens.

    I tried everything the DJI post said, at the same time, but the issue still remains.
    • I quit all applications before opening DJI Pilot app
    • Airplane mode on
    • No sunlight on the iPhone (flying indoors and it's winter here)
    • Hardware decode is ON in the DJI Pilot app
    • Transmission quality is set to the lowest setting possible
    • Flight route is turned off
    My Phantom 3 Advanced is now an expensive pile of worthless gear.

    Contacted support and waiting for DJI to tell me what they'll do for me.

    It occurs outdoors or indoors.

    I'm posting this video because I think this is a really, really nasty bug that should get even Apple concerned, not just DJI. Let me explain.

    Apps in iOS are "sandboxed", which means that they shouldn't be able to crash one another, let alone freeze the entire device.

    But that's not all; you see, half of my freezes are followed by the apple logo screen, so it was a freeze + restart. But half of them are just nasty freezes, where the iPhone simply doesn't reboot.

    I wonder how many people know how to reboot an iPhone, since it's not trivial (holding the power button does nothing).

    i suggest to replace the Iphone with another tablet or platform and try with it, might be an iphone issue not necessarily from the Drone itself, i have seen such issues with inspire's 1 earlier these months, freezing iphone's and video feed, there is a lot of issues that can have such impact such as distance between controller and drone, its recommended to test the video link at distance first, try to record and test your video feed as-well, antenna direction also might affect video input quality... im feeling you and trying to help you out get your bird up asap.... so far id say try another phone tablet and let us know the results

    Mine was flawless while it was on 1.1.9. Did tens of flights without any issue whatsoever. The problems started when I updated to 1.2.7 and 1.2.8 made it even worse.

    Thanks a lot for the feedback guys. Next week I will have access to an Android tablet to run some tests.

    I have tried with my father's iPhone 6 and the issue happens exactly the same way, so it's not a faulty iPhone. Also, everytime the crash happens I have to power cycle the iPhone, so it's not that.

    I will give the android device a try and report back.

    It seems like you only have 3 satellites maybe that could be a problem
