Mine flew away yesterday without any error showing in the screen. I had to switch it off while flying because it was flying fast and i didn't want it to harm anyone.. Anyway, it crashed inside an abandoned cemetery

I have the log
I have the camera footage as well

one of my friends told me to not waste my time because dji will not replace it for anyone.. is that true?

Sorry to read on the accident, did you retrieve the drone in the end?
We will repair or replace the drone if the accident was caused by non-pilot error, please send in the drone for data analysis if it is still in warranty period.
Please contact our support to start a ticket in working hours.

DJI is awesome! This is especially true when you purchase the extra (whatever they call it) coverage or insurance for $100. Fix or replace your Mavic during the first year - twice - provided you can return the drone. Cost $80 the first time (already used that one) and, I think $180 the second time. My crashed due to pilot error - forgot I was flying it (sounds odd) after setting the home point (unintentionally) over my patio under a lot of trees. The Mavic tried so hard not to crash, but once the batteries died, it did too. (I was filming the sunset in tripod mode, got bored and started doing yard work... oops! What a surprise as I raked leaves and find a Mavic among the pile!)

It’s something you just don’t know whether they will replace or give you a discount “usually 30%” off buying a new aircraft , also remember you still have a RC value €350.

Are you still able to power on the drone? If so, please retrieve the flight log (DAT file) from the aircraft before sending it to DJI. The instructions for retrieving DAT files are here and once you've accessed it you should upload it to DropBox and provide a link in this thread. The correct file will have a date and time that correspond to when the flight occurred and be tens or hundreds of megabytes in size. If you aren't sure which is the correct one then just include all those that you think might be from the flight that ended with a crash. The video might also be helpful so please upload it to DropBox and provide a link to it as well.

It appears likely that this occurred because your Mavic's compass was affected by the steel rebar in the concrete from which it took off. If you send the drone to DJI they'll examine the same DAT file that I requested above, which will provide a better indication of what happened. Assuming they confirm this diagnosis then it isn't likely you'll get a free warranty replacement as technically this would be a case of pilot error.

with so much metal everywhere, why would taking off from concrete be a "pilot error"? I take off from a metal roof, concrete, boats, ext ext. I never seem to have compass issues while doing it?

Because the manual specifically says to avoid metal.

Then you've either gotten lucky so far or the metal you're taking off from isn't ferrous (e.g., aluminum).

It simply looks like compass problem and it’s most likely you had it from the launch, you almost certainly picked up some interference from where you took off or immediate surroundings, it’s strange that it didn’t go into Atti mode as it usually does, it stayed in gps and was responding to your stick movements but I presume not correctly.
That fact that you say you received no screen warnings is very strange, maybe just replay your flight in your app to reconfirm this, because you really should have and it might have been a signal to you to try to land, because you still had gps and although it may have been difficult with a warning you had some chance.
Try getting your dat file up I’m sure droneflying will be able to find out a little more of what happened.

Good luck.

Wow, thanks for the heads up.........

Does that mean you never launch from concrete? How far away does one need to be from concrete? Thanks for the response DronFlying.

I sometimes do (launch from concrete) but you have to keep an eye out for a warning about compass interference and sometimes just a very small change in location can have a big impact.

The best thing to do is check before launch to see if the aircraft icon (arrow) in the Go app is pointing in the same direction on the map as the aircraft is actually pointing: if they're different then your compass is being affected by metal and something like what the OP experienced may occur.

As you indicated, though, it's possible to repeatedly launch near metal and not have anything happen. There was a thread quite a while back from a guy who launched from a bench he had taken off from many times before, but eventually he took off just a little too close to the metal posts supporting the bench and his Mavic ended up crashing.

My mavic fly normal, there are no notice error, when a height of 53 meters and distance of 276 meters when I was taking pictures suddenly drones my connection disconnected, the look on the screen remote blank as well as on the screen mobile, I was worried drones I flew away, but it turns out drones I go back to the starting point when fly, whereas in the remote and screen mobile I still blank, thank the Lord, I am grateful my mavic can back without any damage the least, that I would like to ask why can occur like that?

Usually when there is any interference or magnet radiation a message popups up telling that there is something wrong. Am a DJI customer since the beginning and I owned many drones and know how to pick the right area for taking off...etc

The situation here is different since everything was perfect till it took off when suddenly it drifted so fast before i switch it off in the air.

If there are any magnetic radiation in the floor then it must sense it before the take off. Now I got kind of phobia and i canceled all my scheduled aerial business because I dont want to lose my inspire pro too!

Yes, sometimes you'll get a warning about magnetic interference, but not always.

Am a DJI customer since the beginning and I owned many drones and know how to pick the right area for taking off...etc

Then given your high level of expertise you should have no trouble providing a link to the flight's DAT file in order to determine what happened. In the meantime, your video looks very much like what happens when you take off from a geomagnetically distorted location, and Google Maps shows that location to be what appears to be a parking lot or similar area that would typically contain steel rebar.

What you provided is a link to the TXT file uploaded to PhantomHelp, but what I asked for -- and what Hallmark further encouraged you to provide -- is the DAT file. They aren't the same thing; the TXT file is stored on the mobile device and has far less information than the DAT file, which is on the aircraft. The TXT file has very limited usefulness in diagnosing magnetic interference problems, which is why I asked for the DAT file.

Very much not true what your friend sad about DJI never replacing. I lost a Phantom a while back. After DJI determined it was no fault of mine, they replaced the quad at no cost. Of course, every case is different.

For people whom said there is an interference, I flew thousand time from exactly same spot with many drones, even with the same mavic pro day before the crash.. I had no problems at all, why now? I honestly have the money and can buy dozen mavics but its not about this.. the problem is this crash made me fear flying my other drones, Imagine this happend and the drone is near my head? it was so fast..

anyway, I've contacted DJI the first day i posted here and till now i did not get any reply. how many days they usually take to reply to emails?

Well, if you keep launching from that same location you may need to do just that; perhaps they'll even give you some kind of volume discount.

So I take it you aren't going to be posting the DAT file from the final flight of the now-deceased Mavic I, correct?

Drone flying please stop trolling this thread and have some compassion. I think it is unfair to assume most people know that concrete structures are reinforced with metal. If there was a compass issue the app should have told the user before they took off or slightly after that. Let's have some positive intent and assume the user did not willfully crash their drone or ignore warnings from the app. I'm just saying let's try to be helpful in a positive manner.

I'm not; in fact, I'm the one who identified the reason for the crash.

and have some compassion

I do, but much less so when the pilot refuses to accept responsibility for a crash that was his fault or refuses to provide the information that would definitively establish the cause.

I think it is unfair to assume most people know that concrete structures are reinforced with metal.

I didn't assume anything; in fact, that's why I pointed out to him the existence of rebar.

If there was a compass issue the app should have told the user before they took off or slightly after that.

I agree, assuming that it can be detected, and I never suggested otherwise.

Let's have some positive intent

Like you did when you accused me of trolling? I see.

assume the user did not willfully crash their drone or ignore warnings from the app.

I never thought, said or implied that. You're the one who's making assumptions that are incorrect, so perhaps you should consider taking your own advice.

I'm just saying let's try to be helpful in a positive manner.

I'm the one who offered to look at his DAT file. What have you have contributed to the discussion of this crash besides attacking me?

I don’t believe people are coming here for compassion, they can get that at home or through friends. I believe they are coming here to try to find out what happened and to see if maybe they might have some recourse with dji.
Is it not better to give an honest view rather than a sympathetic I feel your pain view, sure that’s no help to anyone.
Sometimes the answers are not what poster wants to hear but the reasons pointed out regarding why some things happened can be very beneficial going forward for that person.

If there was a software glitch it will be ignored and you will be told that DJI will NOT warranty it and it's pilot error.

Don't expect much in the way of working with someone who listens to your issue and understands how the Mavic really functions.

You will be very frustrated and have to make many phone calls and send many emails all to be told pay us..

Aerialgraphy from the video it looks like you may have launched your drone from the roof of your car, is that accurate? I agree the software should have warned you of a compass error which is odd. Obviously looking back is 20/20 and it's a lot easier to see what happened when you have a bunch of data to sort though then in the heat of the moment.

That's one of the things the DAT file will show but the TXT file doesn't: whether the aircraft detected a geomagnetic distortion. If it didn't then I'd think that his chances of getting a free warranty replacement would be significantly greater, though I'm never inclined to guess with any certainty how DJI will handle a given case.
