I know I 'm hoping desperately that new fw and sw will help, but, at present my spark is U/S because video feed lags by up to 20 secs and is scrambled, on my motorola phone and samsung tablet. They probably aren't approved, but they used to be fine.
But any one have any idea why it's ok about 10 % of the time,especially for a minute or two after switching on?

I had that with my LG G4.
Permanent lag, but really long, up to 20-30 seconds only on one "difficult" location, a reservoir on the dam, lots of steal, also some other interferences possible.
Mostly it went direct black, on other locations. ;-)

I was going to post about this.  I have a new Spark with RC, iPhone 7, everything is updated on the AC but I have not recently updated to new iPhone software because of issues Ive seen posted.  Video lags and skips, It makes me think I'm going to loose connection so I always immediately fly back when it occurs which is making flying less than enjoyable.  Anyone else having similar problems or have a fix?  Do I have anything to worry about with it lagging like I'm going out of range?  Im only about 500ft out when its occurring but after already losing one Spark I'm very cautious.  I worry if I push it when it starts lagging Its going to have a total disconnect like I recently had.

Mine used to do this. Huge lag. Un flyable. Got a newer, faster phone. Did all the updates. Since then no problems.

Try turning off video caching in the DJI Go4 app, and let the AC record to the on board  SD card

I wonder if that is gonna fix (or improve at least) our "always present" image transmission issues. I hope so.

I'll try and tell.

Thanks.

Iannes.
Thanks for info. Made much improvement, but lag builds up after a while.
SD prompt seems to control sd card on device , but not sure. Setting cache size makes no diff. Seems to default to 3 gig which is spare capacity on  tablet card. Perhaps card is too small?
All works fine on otg, but cable is a bit of a hassle.
I think you're right, problem is caching. Thanks very much , I 'll keep trying.

Glad we are on the same page. Please do keep us posted on the results.... Anything that helps would be great as every fix i have been advised hasn't improved things so far and this video transmission issue seems to be affecting a lot more people suffering the same issues these days!! I can't get any further than about 50m without losing video, yesterday i was flying 12m away from me and had the weak video transmission, it actually made me laugh!!!

Well as I say OTG works well. But shouldn't have to resort to it.
Some setting changes seem to take a while or a re boot.
Thing is it was alright.
Tried 32G class 10 in device, no better. 8G class 10 normally in it with 7 Gig spare.
Only 16 Gig device with 3 Gig  available, so could be struggling.


Phone motorola moto g 3rd generation better but still laggy.
Again fine on OTG.
Hope to try 32 Gig device if I can find one.

I think those image transmission issues are not related to the wifi between phone and RC (or are less related), although maybe using OTG and switching off the very all signals (bluetooth and wifi) could make it easier to get better image reception, I rather think that the problem exists between RC and AC. Maybe they don't find the good software for that hardware, or maybe that hardware is just not good enough for what it's supposed to do.

in the same way, I think that disabling video caching will not solve the problem since I assume that the only thing the phone does is to save (or not) the images that it previously receives from the AC, through the RC (and there we have the issues).

Anyway, I'll try it and tell the result.

Cheers

I find that using the OTG cable fixes all the video lag and complete disconnects that I get with my Android devices.  I also don't find a need to shut off Wifi or Cell service on the tablet I am using with OTG.

Thanks for interest everyone.
Using OTG is better,but I should not ,indeed ought not have to use it as we all know by now.
  I've never had bluetooth on.
It could be between AC and RC, but surely everyone would
be suffering.
Let's all meet in Birmingham in a car park and we can all try everyone else's phones etc.(DJI to pay petrol)

You can try to reinstall the app, fly the drone in a place with less interference. Besides, you might need to switch the device to airplane mode and shut down the Bluetooth. If steps above don't help, I advise trying another device.
