Well Im speculating it being the firmware as I didn't get any warnings before hitting the wall.. I flew fairly fast (about 33-38km/h) sideways in Position mode.. so though it may haven't stopped it from crashing.. I just wonder why I didn't get any beeping or warning from the avoidance system at the building was a huge apartment building with brick walls and regular windows.. I hit the bricks.

The sideway sensors (or lateral based on the terminology used by DJI in the manual) are only working in specific intelligent flying modes.

If you were using the drone in mode P as you mentioned before, then it is normal that side way sensors were not protecting your drone. Friendly advice is to have a look at the manual in order to get a better understanding  of how the sensors work.

Normally I tend to use my own sensors and see the Mavics as a fallback solution if anything fails. I would never rely on it.

DJI has been silent for two days. No information, nothing happens. It looks like we were left alone with the problem. Whatever it is, I do not think it takes more than one week to fix problems. Even if it is a bigger problem, one should focus on one problem, eliminate it, release the update and solve another problem. We are now experimental rats. "Show film and logs are our technicians will check." Buy an Android phone and check it out yourself. ;) The update made me worry about the safety of flying, and that I can break down the drone, which would be the smallest problem, because you can hurt others. I am asking DJI for decisive actions, such as the recommendation of a downgrade firmware (it does not guarantee the drone's top efficiency) or anything other than taking water into your mouth.

So the sensors worked before firmware was upgraded.

The second video is from the same day after another fumigation update! It is clear that the sensors are included but when they take off they do not work!

Susan We have 271 comments on this topic, half of them refer to the problems I mentioned. Do I have to explain more ?? If it's an Android problem, fix it because I can not fly safely.

Thanks for getting back to us. As discussed in this post, there might be some confusion or misunderstanding after updating the firmware. For the Android problem, do you refer to the internet error? If you have the same troubles, please kindly provide the mobile type, mobile OS, App version and corresponding upgrade log(dji/dji.go.v4/log/cache/up_new_all), we'll collect and forward to our engineers to check the exact status. Again, we sincerely apologize for the inconvenience caused.

Pavel.Donev Posted at 2018-10-16 03:38
The sensors do not work and light! The screen shows that they are off! Check out the video I uploaded! The landing error is more difficult! Appears every time!

Thanks for the clarification. The sensors will not work when the drone is during the landing period. As for the Obstacle Avoidance Temporary Error, I've forwarded to our engineers to check and will keep you updated on the latest progress, thanks!

kkent Posted at 2018-10-16 05:07
Totally agree. Used to overcome it before by setting shutter in photo mode and then entering HL mode, but now even this was 'fixed'. There was  ability to shoot wonderful night hyperlapses, and now it just gone.

Hi kkent, as the optical measurement technology used by the Mavic 2 requires continuous image information, so if the shutter speed is too low the video bitrate will stop, causing the visual measurement to fail; therefore the minimum shutter speed is limited to 1/30. We continue to optimize the shutter threshold to ensure the user's flight experience, please pay attention to the firmware update, thanks!

Hi Susan,

You may want to tell these people that complain about obstacle avoidance and show pitch black camera images that the vision system is optical not radar or Infrared and does not work of a night.

Hey Brian, thanks for heading up. For crash accident, it will be better to check the flight records and flight data to confirm the exact status, we cannot speculate the reason without any data.
Also, we suggest our users read the user manual carefully and use the vision system properly. Wish you all have a good time!

Updated the new Oct 2018 FW on my Mavic 2 pro using DJI Assistant via a PC a week ago.

Some issues after the FW update.

Hi there, if the OA does not work during the flight and invalid bottom lights, please kindly upload a short screen recording of your operation when the two appear, we'd like to check the exact status, thanks so much!

RichJ53 Posted at 2018-10-16 20:07
Hi Susan
Thank you for asking and giving us this information. I guess, I would request that your engineers reconsider this option. The Mavic series are smaller portable drones which means you travel with many batteries. We need the ability to discharge the packs sometimes before 10 days....   Please reach out again and see if we could have this option reinstalled.

Thanks for your suggestion. If there is any change in the future, we'll release on our website.

RGMGFitness Posted at 2018-10-16 09:55
Just a reminder to folks regarding the 4th item in this announcement;  "Enabled Lateral Vision Systems for QuickShots sub-modes of Circle, Helix, and Boomerang.".  Unless DJI is changing their position on this you still want to be careful using the lateral vision systems.

Also, DJI ADMIN...maybe pass along that the user manual needs to be updated as well (perhaps someone's already working on that).

Thanks for your suggestion. This will be forwarded to our engineers to check.

dv8ed Posted at 2018-10-16 20:23
Previous firmware and latest firmware still getting this incorrect image on Android 4.3.2 shouldn't it say OA disabled like iOS? It's when I switch from P to Sport mode.

Hi dv8ed, the sensors will not work during landing. As for the Obstacle Avoidance Temporary Error, this has been forward to our engineers to check. We'll keep you updated on the latest progress.

Nelsonlee Posted at 2018-10-17 00:18
I don't know what actually DJI engineering dept doing, every times come out with new firmware have not tested properly and just release to public and we are the one to update/test/crashed/error....etc then report on the forum.

Do DJI really think of us, we spend so much money is not for tester, we need proper firmware/hardware/software....etc.

Hi Nelson, we're sorry for the unpleasant experience. Generally, the new firmware will fix some previous issues and introduce some new features. We keep optimizing the experience and very sorry if this bothers you. If you encounter any troubles with the update, do not hesitate to contact us.

Akossss Posted at 2018-10-17 01:56
The only thing I don't understand, why no one can upgrade using the app? Okay, Mavic 2 arrived with pre-released fw-s, that had upgrade issue, I accept it. But there was an upgrade since that, even the app has new version number, but still nobody could do fw upgrade through the app. Why? This feature work in every other model, but here...

Apart from this, upgrade was successful using the Assistant, sensors are okay, everything seems to be okay (2 test flights so far)...

Hi Akossss, may I know which mobile do you use and what's the current App version? You may clear the cache or reinstall the App to check. If the issue persists, please kindly export the upgrade log( dji/dji.go.v4/log/cache/up_new_all) for better assistance, thanks!

fanscb6385d2 Posted at 2018-10-17 03:57
Susan, thanks for your reply.

But if this FOV "4K" with 2.7K quality, is the best DJI can get out of the sensor, due to hardware limitations, why call it 4K?

The Mavic 2 has both HQ mode and FOV mode, we're sorry if this bothers you. As to precision landing and waypoint, we do not have the timeline for now and will release as soon as they are ready. Appreciate your attention.

Hi Peo93, I'm so sorry to read the accident. Please kindly start a case and send it in from here:
https://www.dji.com/support If you have any doubts about the crash, we'll arrange data analysis if the unit is under warranty period. If you encounter any difficulties during the period, feel free to contact us with your case number, we're glad to help.

ChristWolves Posted at 2018-10-17 08:23
I have two comments for the new firmware update on Android 4.3.2:
1. Transmitted image on the screen appears to be having dreamy effect
2. Obstacle avoidance system is totally failed, I.e. NO avoidance in all directions of the flight.

Hi Chris, just as Vendex mentioned, the VPS will not work well in the night, you may test in daylight and confirm. As for the dreamy effect, you may adjust the ISO and check whether it helps.

DJI Susan Posted at 2018-10-19 00:15

It's clear from the video that this is on take-off!

Thx Susan to keep us updated! I hope this sensor/OA problem will be solved quickly.

fredbotton75 Posted at 2018-10-16 12:41
DJI Susan, would you give me some details about the Remote ID stuff introduced with this firmware? Is it related to AeroScope? To national regulations? What changes with previous remote information sent over the air?

Hi Fred, may I know where do you read the Remote ID? Could you upload the screenshot for better assistance?

Tomasz Kierepka Posted at 2018-10-15 04:41
How many restart u made after sensors back? I made 3 and nothink better

I did the update at the sunset that night did couple of restart, but not until the next morning.

KlooGee Posted at 2018-10-14 19:39
Were they disabled when flying or just when on the ground?  If you've read any of this thread, you will see that many have discovered that while on the ground, the sensor shows disabled, but once launched, it works normally.  Is this the behavior you see?

sorry for late reply , new here.., the sensors were not working on while flying. switching to sport to program and tripod mode changed the fly sensitivity, but the warning sensors and alarms were quiet at that time.

DJI Susan Posted at 2018-10-19 00:56

Thank you Susan

We continue to optimize the shutter threshold to ensure the user's flight experience, please pay attention to the firmware update, thanks!

This is not correct information when put into practice. Using a MUCH lower shutter speed has never yielded a fail and tracking the target/subject is flawless.

In other words, when flying the Mavic 2 Pro in Hyperlapse with a ¼ second shutter, ISO 100, f/5 (for example with ND filter), the measurement operation performs as intended.

Now I could see how it would fail if the exposure was blown out or too dark, in which case, the operator probably doesn’t know what they are doing at all. However, the other 99% of us are more than capable of setting this all up in Manual Mode just using Live View.

Thanks for the update

DJI Susan Posted at 2018-10-15 01:55
Thanks for the clarification. Could you upload a short video of the issue? I'll double check with our engineers to see if the issue can be figured out remotely.

Hi Susan,

Here is the video. Problem started immediately after the firmware upgrade.



Thank you

Pavel.Donev Posted at 2018-10-19 02:46
It's clear from the video that this is on take-off!

Actually, I have checked your video several times, for the red icon before taking off, it is normal for Android device, no worries.

Brentjuh Posted at 2018-10-19 03:07
Thx Susan to keep us updated! I hope this sensor/OA problem will be solved quickly.

Hi Brentjuh, may I know which specific question do you refer? For the OA issues, there are some points need to be clarified:
1. Before taking off, the sensors icon will be red in Android, this is normal. We'll optimize the experience in the later version.
2. The sensors will not work during landing, this has been mentioned in the user manual.
3. As for the obstacle avoidance temporary error, I'm checking the exact status with our engineers, will keep you updated. If there is any other question, feel free to contact us.

Well, I spoked too early. Yes, I crashed the mavic in my garage. It got confused. Did not reconized were to avoid the garage door. Only minor scratch on the lateral propeller at 2 foot height.

Issue while flying

Have you tried downgrading the firmware?...I have not updated yet and don't think I will until this and the sensor issues are sorted

hawkyzf Posted at 2018-10-20 07:14

Yes - that's the first thing I tried. I've downgraded, upgraded, refreshed, did pretty much everything I could think of.

Not looking good...

You know...........If this problem NEVER occurred before the upgrade and ONLY came about AFTER the upgrade, now going back and after a downgrading, this new problem is STILL occurring? This  implies 2 things in my mind, one of which (#2) i've always suspected of DJI's firmware up/down grading processes

1) The upgrade somehow caused a hardware failure and of course, downgrading can't fix hardware failures........Small possibility

2) DJI is leaving remnants (still 100% functional code) of the current code (intentional or not). e.g., The downgrade processes aren't truly overwriting all data sectors/areas when re-flashing  to older FW.

" Downgrading" ISN'T  truly 100% going back to the previous version of  the FW.

Problem never occurred before the upgrade. It appeared immediately after the upgrade.... after the first reboot.
Let's see what they have to say... I'm still hopeful it's not a hardware problem but it's looking unlikely now.

If problem still issue so did you downgrade firmware and can work? Because i concerned that after upgraded firmware and bugged in hardware which cant fix. Only sometime DJI will give beta firmware to fix hardware but not 100%. Depend on your log data so tech will see whether can fix or not.
