Hello everyone

I have had my mavic for just under a month, I have flown it loads about 40 flights in total and everything has been amazing, I love it. But yesterday I went out to the local park to fly, I connected my phone to the RC and everthing was working perfectly, I took off and was hovering at about 20m and i was looking at the screen and suddenly it said "disconnected" at the top, I assumed this was a signal problem so i landed the mavic and restarted everything and tried again but now when I power on my RC and plug my phone in it doesnt connect to the phone, I have tried with multiple phones and it still does not connect, the phones does not aknowlege that it is connected to the controller. I then tried to connect the phones to the USB at the bottom of the RC and still did not connect, the app acts as if there is nothing connected. This must mean there is something wrong with the RC, I then tried to downgrade the software on the RC but it does not connect to the PC, the Mavic connects fine and i tried downgrading that software with no prevail, the RC still charges as normal but seems like there is no data transfer through both micro USB and USB ports on the RC.

If anyone knows what the problem might be please help, Thank you

Aye was thinking cable here. But both ports? It sounds hardware failure to me. Charge it up and connect to the assistant, try both ports. Else it's probably warranty.

Might try using other cables too, eliminate as much as possible.

If you are using the USB on the bottom of the rc make sure that the cable on the side is unplugged from the rc

Did you try to link the remote to the AC? Did you delete and reinstall the GO APP?

With mine sometimes, the RC and the AC connect but the app won't display the GO TO FLY. I had to shut the AC, then shut the RC then restart the RC and the AC and then turn on the phone and GO 4 APP and then it connect. Sometimes I had to do it several time.

I have exactly the same problem. Had my Mavic for one day. Everything worked perfectly. After the first few flights the RC won't connect anymore. It is stuck showing "Connecting...". It doesn't connect to Assistant on Macbook. It doesn't connect to IPhone via USB. I have no way to reset it it seems. HELP!

The RC links to the AC perfectly, i have uninstalled DJI go 4 app multiple times on IOS and android and still no connection, even tried the lichi app and still no connection. Im pretty sure it is a problem with the actual RC software or hardware, but i cannot upgrade/downgrade the RC as it does not connect to Assistant 2 software.

i have an iphone 7plus... which firmware do you have? i attempted to downgrade firmware but issue seems to persist.

this is a wild theory but could it be related to battery life on remote/phone? i started with 100% but the issue kept on reocurring when battery hit 75% (and phone went below 40%)

I started with latest firmware on all components and then tried downgrading Mavic AC and RC. No joy on the older firmware either.

I had also wondered if it might be battery related but hadn't thought to try at a full charge yet. will give it a shot and see if you're on to something.

spoke to support via chat which wasnt that useful, however i found out a combination to reset the controller:


* Turn on the controller, and the aircraft should be off.
* Press C1, C2, and shutter on the controller then turn the controller off.
* Turn on both the aircraft and the controller and link the remote.

yeah i was told the same thing but this seems to do nothing, does anything come uo on the display saying 'resetting' or something because it just seems like the RC turns off and on normally and does not seem like it has been reset. it links up to the AC without linking them back together.

nothing comes up on the display. i tried holding down the buttons and also pressed them only once. very difficult to tell if anything actually happens... the funny thing is that my remote manages to connect OCCASIONALLY (1 out of 20 attempts).... very unhappy at the moment. i want a new remote and not send the damn thing in and wait for ages

Tried the reset buttons as suggested and no effect.

Also tried to do a 'restore factory defaults' in DJI assistant2.. That fails every time.

Computer based assistant ? New firmware upgrade didn't help either

FOUND SOLUTION... it worked for me in under 30 seconds.

it seems for some reason the aircraft just un-linked itself from the RC, so all what u need to do is to link it back.
refer to user manual page 36 to so that,
here is the user manual link: https://dl.djicdn.com/downloads/ ... ser+Manual+V1.2.pdf

i went to my RC, put it on, linked my iphone, turned on mavic, showed disconnected aircraft,
hit the 3 dots menu on the top right corner, go to remote control, scroll down all the way, and hit linking remote control, u hear a beep and u have some 45 seconds to go to ur aircraft,
open the side where u have ur sd card, and hit the small tiny button once...
this is it, worked perfectly.

let me know guys what u think...

I'm having the same issue. My RC connects to the aircraft, the but phone or any mobile device doesn't connect to the RC. This is the 3rd unit I've gotten back from DJI. Where is the quality control when units leave the service facility!? I'm beyond upset with DJI and just want my money back at this point.

I've flown my Mavic for maybe 30min...spent 3 month sending it back and forth. I hope they make an exception for me and let me return it.

IT IS NOT THE SOLUTION. We have tried his obviously. RC doesn't connect to mobile device so you can't link the way you described. Read thread properly.

I feel the same. The after sales service isn't satisfying and takes ages. I won't wait for a replacement for weeks when my drone is faulty after 1 day. I ordered a new drone and will make use of the return policy

Yeah, but I was past the 7day return period. Everything was working great for me till the main board went bad. DJI replaced it but only to give me a new bad unit...then that was sent back and returned again a bad unit. I feel so bullied and jerked around.

I paid so much for this thing and now I'm the asshole.

Just got my repair report back from DJI. They're replacing the whole aircraft. They didn't say what the issue was though. Luckily it was fully covered (+$1000).

I'm having the exact same issue.  DJI you know this is an issue.  You need to either fix this or Overnight us new remotes.

DJI this is unacceptable.  Do the right thing and take care of your customers.  Find a solution or Overnight us new remote controls.  

This is YOUR FAULT DJI!.  Don't make us spend countless hours trying to solve this issue, figure it out on your end and send us new Remotes.  Don't make us suffer.  Do the right thing!!!

Hi, I have the same issue and I already wrote to the support, but still no answer...
How much time was it for you to contact with the DJI, send it back and have a refund?

pretty much the support was utterly useless. they havent managed to scheduled a refund, however since the drone was less than a week old I reordered a new one and sent the faulty one back. now they want me to pay for the return-shipping costs for their faulty product. incredible. 18 EUR EU shipping for their fault. cant believe it. i will make a huge hazzle with the hotline etc. until they refund me those 18 EUR

I am rather upset as my mavic is only a few days old (21st of February) and it was working fine until the update...

I'm having the same issues right now. This is my second unit and it already behaves worse than the first one. This one gets super super hot and eats thru batteries in a matter of mins (15 mins or less) The camera is constantly out of focus and now it's not connecting to the app. It will link RC to AC but shows disconnected. Was y'all ever able to find a cure??

I had the same issue, phone wouldn't connect through the GO 4 app. i tried different phones and tablets. In the end mine was a simple fix. The forum log in and the app log in using my e-mail address had to be the same. In other words, all your different phones and tablets have to have the same log in and email that you use on the drone (app) and the forum. This is what solved my disconnect issues.

Good luck
