I don't initiate the return to home but it says on the screen that the mavic will return to home in however many seconds & then I have to cancel the return. This happens quite often & don't know why it is happening.

I"m sure the moderators will ask so I'll just jump in and as as well, can you provide any more information about when this happens, what you are doing, the environment your are flying in, any video or logs.  The will definitely want you to sync your logs and upload them to a dropbox link.  Any screenshots can also be helpful.  

What is the battery level when this happens?

Did you capture some screenshot when it says return to home? Could you please clarify your current firmware version?

any update?

Maybe you've set the low battery warning too high?
But yeah... some logs would help..

I've the same problem, any solution found?

I'm not aware of any solution because I've never seen a case where a Mavic spontaneously ("randomly") initiated RTH. There's always been a reason for it, whether it's because the user requested it, because of a low battery, or -- most commonly -- due to a loss of connection between the drone and controller.

If you'd like to find out why it happened in your case then retrieve the flight log (TXT file) from your mobile device and upload it to PhantomHelp using these instructions, after which you can post a link to the uploaded log in this thread.

Another log, same problem after one minute, two minute and four minute:

sometimes i push buttons by mistake on my RC - u not perhaps pushing the RTH button on the RC by mistake. Or maybe a poor cable/usb connection between RC and devise or critical battery warning set to high?

No mistake, the RTH initiate four/five/six time in a row after manually cancel it... see the log

I'm not sure exactly what specific error "Other (9)" represents, but it appears likely to be caused by some sort of compass error, and it appears that you should have seen warnings in the app before takeoff. What I do know is that the log shows that you took off despite being in ATTI mode and that the Mavic overcame the initial compass problem once it got off the ground, but in the meantime there was some yawing that wasn't caused by stick input.

I do also see six times where it initiated RTH and I can't really explain why that occurred if you didn't request it, but I suspect it's related to the problems that I mentioned above. Be sure your Mavic is well away from any metals or other source of magnetic interference before taking off and I doubt you'll see the RTH problem again.

Hi fans3be4122 - so i looked at yr log, my first ever, here's what i thought.
seems to be 2 issues at first - 1st is the warning zone, i do not think this restricted you.
2nd is a compass interferance issue - if the pier you launched from has metal in its construction, this will likely have caused the compass interferance issue.
Satelites look good but at first you are flying in ATTI mode and i think  Other (9) error relates to this.
Trying to be brief it looks to me like this:
Before take off your compass had not 'set ' itself due to apparent local interference.
Satelites were sufficient but you were in ATTI on take off not GPS mode - this possibly because you took off too fast (i do not mean at high speed but rather that you took off before gps mode properly kicked in - this always takes a bit of time and will be indicated with a green notice top left of screen).
Perhaps GPS mode was taking long to kick in because the magnetic interferance was freaking the system out.
Try these steps before take off:
Only take off when the app says it is safe to do so -It will literally say something like "it is safe to launch" (i think) - by this time the red notice bar (top left of screen) will have turned green.
Only at this point has the drone done and completed its nesessary calibrations and satelite connections and only then is it safe to take off.
Metal in close proximity to launch pad (eg, next to motor car, on concrete droveway with reinforcing bar, a metal table etc) these will all interfere with compass calibration - you must move to another spot.
Only take off when the app says it is safe to do so - it is not a long wait typically. if it is taking long then there is a problem and you must identify and remedy that situation first - good luck

I try in a few days with your suggestion, and I'll leave feedback as soon as I can

Another log: http://www.phantomhelp.com/LogViewer/IHLNFAT9DTEDD0DZZP1R/
This time RTH start after 2m20s, in P-GPS mode, no warning before...And after 4m40s, start three times, always in P-GPS mode...
I'm very sad about the situation, Mavic is buggy...

Same happened to me yesterday. Took off after RTH set but was flying about 20-30m above our flight hangers when I got a rth messgae, but not the normal pop up with slide to accept.

It went away after a few seconds. I think it was due to the fact that the hangers have a lot of metal and it interferes with the compasses.

Could be why your drone did the same.

I will check at another area and see if it still does the same.

That would have zero to do with RTH.  

I’m having the same problem I’ve just  flown mine on Wi-Fi  and it was fine so must be my controller ?

it might be that your homebutton is pressed not by you, but if you have apened the controller or the factory made  a bad product the button my be pressed automatically or the switch on the board is broken you would have to open the controller and check if the return to home button function

Hi,

Do you realize that you react on a question asked in 2917 & 2018 ??

cheers
