It appears that I'm not the only one that's having a problem with poor image transmission. (Go4 app & firmware up-to-date)

The image transmission is so bad that I can't use Sport Mode without it losing live image feed... very scary.
I can even be holding the AIR and just move it quickly in my hand, that's enough for the image to lag behind in a choppy / jumpy manner.

I've tried a few things:
- updated / refresh firmware through DJI Assistant2
- uninstall then reinstall Go4 app
- disconnect then reconnect RC
- tried different wifi channels manually

I have also own a Mavic Pro and two Sparks and don't have any problems like this...
It's such a shame as I preordered this drone from DJI online store (I never preorder anything - I always wait some time to see what happens with the first units... I went against my usual stance on preorders and am now regretting it... lesson learned..)

Anyway, hopefully people use the poll in this thread and it gets DJI's attention that there's something very wrong with some of these units... I wanted so badly to love this product... even went to CES 2018 specifically to see if DJI would announce somthing new... very frustrated..

Thanks for participating, everyone!

Your implying this is across the board, but that is not the case the bulk of people using MavAir are not having problems with this. I would recommend that you let us know what setup you are using what wavelength in what type of area you are flying in and also post some videos of how bad this really is.

I don’t think regretting your pre-order stance is going to help. I preordered and am very happy. If you’ve a duff one then go down usual channels

Putting your phone in airplane mode is essential, I have tried both ways and transmission and interference is rough without being in airplane mode.

Do I still have a map in the bottom left corner when in Airplane Mode ? Or is it just blank ?

i have that same problem with my mavic pro - even if i hold it in my hand a turn the drone the picture lags. Making my problem so much more frustrating is that it is never consistent. Sometimes will be fine for a while - then for no explained or understandable reason the image blurr starts. Often it will be there at the start of my flight and then disappear for a while but almost always on and off again and mostly when my drone is close to me.

If you're having issues, contact support -- what you described doesn't match what I see on my mavic air.  MAYBE if I am in a really congested area, then it will not give me great signal, but only at a distance.  hope this helps

What are you using as the screen device. Some devices simply don't have the processing power or have too many applications running for it to work well. See if you can find someone with an Ipad Mini 3 or 4 which will test if the drone transmission is good or not.]

The Ipad Mini 3 or 4 is by far the best screen device for this drone. Also make sure all other devices you have near you or on you are switched to Airplane mode or off

Yes, I've flown it twice - once in Sai Kung (rural area Hong Kong) and once in Philippines (Anilao - rural, some resorts).  in both cases I couldnt get much past 600m without completely losing transmission signal

[Edit] - Just saw some replies.  I've tried with iPhone 6s and with iPad Mini 4, is the Airplane mode the issue here?  Seems odd.  I have seen some answers relating to switching frequency, is this an option in Go app?

Then, more and less the 10. flight, i have lost mine over the jungle, for ever. :-(
Hope DJI will offer a replacement drone for not the full prize.. :-/
In future, i would not fligh away more than 200m...

For me..when I use a tablet I get a terable range and connection, but when I use an old cell phone that I no longer use for cell service I get 6500 ft with no problems.TRY A DIFFERENT DEVISE.

I have the exact same problem... 10 flights, only one I was able to reach 890meters in distance... and never more than 100m high...

The other flights I lost connection before 100m in distance.  Is that normal ?

It's secure to change from 2.4 ghz to 5.8 ghz ?

Thanks

I'm having trouble with weak signal issues as well.  iPhone 8+ (256) always on airplane mode.  The problem seemed to really get worse with the last firmware update.  I'm testing an iPad Air now.  I've always used AUTO mode for the Wifi.  I'll try to test manual settings with it as well.

I got my MA three days back. On Friday on maiden flight everything went fine. I was loving my new MA, on Saturday i installed new firmware update. I got no image transmission problem, but i thought it is may be some radom. Then today i got it twice. On anroid as well as on ipad. This is scary. I thought i could fly more than 300m. But now i dont have that confidence. If this will continue i am going to ask for replacement from my local shop.

I always restart my phone before flying, to minimize the number of other mobile apps that are running in the background. I know you can do this on Android by killing your background apps, but I prefer the clean reboot and then wait a few minutes for the phone to settle done. If one of your mobile apps decides its time to update something, that could well mess up the video quality on your phone / device because your device is doing too many things at once.

I also put my phone into Airplane mode not only so that I don't get any calls while flying, but also to minimize the stuff that other apps might do in the background that would cause issues.

Can you post a screen snapshot of your Wi-Fi screen near where you're having this issue? You may find some clues there.

I have the same issue with my Air for sure. I even exchanged for a new one ensuring the production month was different hoping a different production lot might solve the issue. No change for me. Using 5.8 ghz set manually for best channel choice, as well as using airplane mode does help, but I still lose transmission at ~1000-1500 ft regardless of elevation. I have the same results whether I use an iPad Air, 2017 Ipad, or an iPhone X. I have a Raptor SR coming int he mail today so I'm hoping that solves my issue, otherwise I just can't build any trust and confidence in this drone.

All this talk about putting devices onto Airplane mode, or killing background apps on iOS is making me laugh, as this is meaningless...

Cellular transmissions occur on completely different frequencies and have no bearing on the efficiency of Wi-Fi transmissions, which the MA uses. Even the ambient EMI caused by the smartphones' cellular radio isn't enough to impact the Wi-Fi transmissions of the MA and it's RC. Cellular transmissions become much more impactful when you fly the MA (or any drone for that matter) close to cellular transmission towers and power transmission lines, as those emit FAR GREATER EMI that can ruin the transmission between an MA and the RC.

Smart watches / health trackers like Apple Watch or Fitbit might cause issues with MA's 2.4GHz band, as those devices operate on 2.4GHz Bluetooth and are known for causing some minor issues, but when my MA had firmware .0300 I always used my Apple Watch S3 along with my iPhone X with all radios on, and never had a image transmission or range issue.

Also with iOS, unlike Android, iOS will suspend all apps that are in the task switcher, so you could be running a dozen apps and the phone won't be taxed at all. Only apps I would close, as they can perform background updates by default, are social media apps like Facebook, Twitter, Instagram, Snapchat, and texting / IM / video conferencing apps like Skype and Telegram. The old notion of having to force close apps on iOS is completely FALSE. Android devices needs to do this as the OS is much worse at handling background apps and memory management.

Bottom line, I flew my MA with an iPhone X and Apple Watch S3 with all radios on, never closed any apps, never did anything special, and it flew beautifully, and never had signal transmission or range issues, whilst on FW .0300. Now with .0400, even my iPad Pro 10.5 Wi-Fi only model, when I use it without my iPhone X cellular link, even to test, the MA can't go more than 150m before video feed starts to degrade, and a bit more distance than that, I often lose signal all together.

This is a FW .0400 issue, not your devices or radios, and we need to let DJI put out a fix for this.

Just took my MA out for a quick test flight, and as it hovered 10ft away from me, the signal kept cutting in and out, with repeated Strong Interference warnings popping up... This is all happening since .0400 firmware, and I'm so fed up with this! I have ZERO confidence in this drone now!

And so here's the funny part... I went to put Wi-Fi into Custom mode, and saw multiple channels were showing no interference, mostly in the 5.8GHz band, so I switched to three different channels; 149. 153, 157 if I remember them correctly. On each change, the drone IMMEDIATELY began to show HIGH interference levels on that channel, and neighbouring channels! EVERY channel I switched to spontaneously developed high signal noise upon changing to that channel!

After landing, I took out my MacBook Pro and scanned using a proper Wi-Fi scanning application to see what was in the area... NOTHING even CLOSE to what the drone was registering!

This never occurred on .0300, and even though this is an urban area, interference in the area, to this magnitude, doesn't happen over night.

I've uploaded the basic log to PhantomHelp and posted the link below.

DJI, this is DEPLORABLE!!! People have spent upwards of $1500 and more with accessories for this drone, and it's turned into a completely useless toy with almost no range, this is UNACCEPTABLE!!! It's been MORE THAN a MONTH since you broke the MA, keep this up and I'm considering a class-action...

I really am also negatively surprised with DJI.
I also got out of heaven (firmw 0300) to hell (0400) and practically no flight for a month.

What makes me more upset is that it was only the DJI release the rollback to version 0300, even if warning of risks or release a Beta.

Only MAVIC AIR has this nonsense of not being able to return firmware.
I usually say that worse than a bad attitude is to take time to fix.

We tried to use one of our spare cells and had this issue. That phone was a Motorola Play G4.  It was choppy and very close to unusable. I switch to my Galaxy S7 active and the problem went away instantly. (same exact place, same exact flying conditions, flew within 1 minute of using the other phone) I was able to reproduce this effect.

I also found that airplane mode does help.

What also help is following the start up steps exactly. That includes plugging in the phone.
Exactly as in the following:

First screen: unfold the MA.

Second screen:
1) Start the MA, wait for the beeps  
2) Start the RC

Third Screen: plug the phone into the RC

This appears to result in a quick connection between the MA and the RC. Not sure why.

I have only really had a bad experience in some parts of the city where there are huge offices or ridiculous amounts of wifi. Always check before you fly the signal strength because it can cost a drone. I was fortunate enough to have had a not too windy day when I was flying and the video signal dropped as it was 400 feet above me in downtown with buildings all around. Luckily, the orientation was easy to detect and it was within line of sight which brought it safely back. Did get a photo of the space needle without flying in any parks, which is a plus as well since Seattle is a bit silly about that.

Ok I went out and got a iPhone 6s Plus 128gig. Replaced my cables with bellin and still have terrible video. My new phone only has the DJI app. All other apps are not working. My phone dose not have a sim in it.
This sucks.
I have tried 2.4 and 5.8, no change.
Just flew today and now it’s bounced in hover from ground to 10 m to ground up and down. Had a hell of a time getting it to land.

Same problem here.

I really cant understand how come device so expensive (for me it was cost over 1000 pounds) can be so bad in quality and service? If I could go back in time I would NOT buy mavic again. Im really disappointed about that product, where ever I go there are always some issues after a while (aircraft disconnected, Ultra sensor error, and now again - bad transmission quality), and I only have it for not even 2 months!?! Ridicules.

About problem with transmission...

It started yesterday after some small update has been done on my phone (DJI PRO 4 app installed something), couldn't even fly for 20 meters. I reinstalled everything - firmware, app on phone, Ive tried different settings, nothing helps, and please dont tell me to try with another phone cause I don't have another one! I have my Samsung Galaxy S8 and so far it was okey to fly on it, it is brand new phone (bought it about 3 months ago).

Would be nice if somebody from Mavic service could reply here and tell us what is going on, and what they are doing about it, otherwise the only thing we can do is to wait. Sad.
