Hi folks,

I have my Sparky only since a month or so, but I am an experienced drone pilot.
While flying the Spark works nicely with R/C, my Galaxy S4 (!) phone (aircraft mode) and  OTG cable, I have problems starting or stopping the video record function.
No matter if I use the record button on the R/C or the record button on the Go4 app, I need to press many many times until the function actually reacts. That's weird...


Video lag is low, I did several flights yesterday on a large free field, no interference at all (I checked it).
I am using current versions on A/C, R/C and app.
Any ideas what the problem might be?

Cheers,
Wolferl

Hi there, sorry for the inconvenience. Do you have a different phone/tablet to use so that we can isolate the issue? Is the issue the same using WiFi connection?

Hm, I just tried the exact same thing on my desk (its raining outside...), and now starting and stopping works as it should.

I'll do some more tests as you suggest, and let you know.

Hi Wolferl. Have exactly the same issue as you do. Sometimes I need to click a couple of times on record button to either stop recording or start recording. And when this happen I also fly on a large free area without any interference. Additionally, the problem appears even when the drone is not that far from the RC, maybe 30-40 meters. It doesn't happen always, but noticed it at least two or three times already.
My setup:
AC firmware: V 01.00.1000
RC firmware: V 01.00.0600
Phone: LG G6
ROM: Android Oreo 8.0 (the latest official form LG)
Connection: Wifi

Hi Vitoski,

Thank you, now I know I'm not alone

It seems it has something to do with flying. As long as Sparky is on the ground, it works. As soon as you are  flying, it doesn't. Weird and annoying thing.

Cheers,
Wolferl

I have a Galaxy S4 and there was no way to make it work via USB OTG with the remote. How did you do it?

To be exact, I have the Galaxy S4 mini VE (GT_i9195i), rooted, and running LineageOS 14.1 (Android 7.1).
Believe me, I was surprised too when I tried a OTG cable that was laying aroung, and it worked right away!

Hi Alexey,

Ugh, that's really bad, I never had that.
I would not mind having recording on at all times, but with recording on, you can't activate intelligent flight modes

I have written many times, I will describe it again:

A DJI GO4 app. 4.1.15 verifier knows everything but everything! which should and have never been such a problem. Handles OTG has all sorts of panorama Stb. Why is it always the latest?

There are a lot of issues in the latest version: weak range, laggy video, delayed video capture button ...

The new versions are coming due to the following: Adding new prohibitions, restrictions, the appearance of new types (Mavic Air) and their bug fixes.
We have Spark owners, nothing new, but worse.

So put it back to 4.1.15 -16 and you'll be satisfied.

One questions though. Is it safe to downgrade from the latest version of DJI Go 4 to the one you recommended? I mean isn't there any issues when downgrading in terms of AC and RC firmware?

Thanks!

There are none!

But I read it every day: the spark flyaway forever, though I just updated it, my remote has broken after I've updated it ...

OK, thanks.
I'll then downgrade DJI GO 4 to one of the earlier versions which you mentioned. Just out of curiosity, is there any place where I can see what changes were introduced between 4.1.15 version and the latest one?

I used to have this problem before switching to an S9+ and no OTG....I have NOT had this problem since switching to OTG. I hope you get it worked out, seems a bit weird. I wonder if your equipment is just not up to the task, you are receiving some interference or if there is another factor at play....Keep us posted.

Jakub what about 4.2.12?
If I'm not mistaken many people in other threads were advising to downgrade to that version.
According to the release notes there were some improvements introduced for Spark.
Do you have any experience?
Thanks.

JFTR:

I did some test flying yesterday evening (at the same interference free large field) just to find out video record starting/stopping works nicely if the phone is connected via Wifi to the R/C.
Of course, video itself is super-laggy and unusable (more than 10 seconds lag). App version was 4.2.21.
Next trial will be the older app versions together with OTG.

I'll keep you updated...

Yesterday I tried the 4.2.12 version and did not notice any massive improvement over 4.2.21 version. AC went to about 60-80 m straight up and already got lag with start/stop recording button. I connected my phone LG G6 to RC via Wifi, as since Oreo there is a problem with OTG. Of course DJI standard answer is that my phone is not on the list of recommended devices.
Will try version 4.1.15 (which Jakub recommended) and let you know.

I have the same problem with DJI Go4 versions 4.2.16 and above. I think the best version is 4.2.12 for me works perfect I have Nexus 6P with Android 8.1
P.S. I`m not using OTG cable, I can`t find any reason to use it when with wifi connection works perfectly.

OK guys, I just flew 3 batteries with the 4.2.12 together with an OTG cable.
What should I say...simply perfect.
Instant video recording on/off plus low video lag (less than 1 seconds).

Hats off to Jakab!

Wolferl
