When trying to download a video, I have to stop and start the process time and time again due to a "Download Failed  Connection Error.  Failed to Download" Error.    The controller and phone and drone are all within very close range of each other.  Is there a fix?

Take the sd card out from the back of the spark and plug it into your computer.

Thanks, that is a nice work-around, but I'd assume the product would simply work as designed too.

Are you downloading the video from the spark, or your phone? I did not know you could download it directly from the spark.

That's the only way I have done videos so far, as I still don't have a good enough phone to use with Go 4. So the videos are on the SD card in the Spark and when I connect it to the computer, the videos I can see the videos in the DCIM folder.

Been having the same problem, i noticed that the RC disconnects from spark then the download fails. i usually just take sd out and connect to the computer but i was away and the sd was full and needed to free up space. was a pain had to reconnect every couple of minutes

you can also just plug a micro USB into your computer and the Spark and pull the video directly from it without having to take the card out.  Just another option.

You canbuse the OTG cable between RC and phone as an alternative

What is the model of your SD card? Please ensure that you use a good one, or you can consider the method mentioned by other users. Here are some recommended SD cards:
Sandisk 16GB UHS-1 Micro SDHC
Sandisk 32GB UHS-1 Micro SDHC
Sandisk 64GB UHS-1 Micro SDXC
Kinston 16GB UHS-1 Micro SDHC
Kinston 32GB UHS-1 Micro SDHC
Kinston 64GB UHS-1 Micro SDXC
Samsung 16G UHS-I Micro SDHC
Samsung 32G UHS-I Micro SDHC
Samsung 64G UHS-I Micro SDXC

I stumbled upon this thread, and I haven't been able to plug my SD card into my computer for weeks (I'm traveling, and simple SD card adapters aren't readily available in most of the world).

I tried clearing the cache in my DJI Fly app, and it worked! So I suggest clearing cache, and then maybe storage, if you're having issues.
