Hello, my DJI mini 4 pro drone had a minor accident. Later, when I activate the protection sensors, when the drone rises from the ground, even though there is no obstacle, the sensors detect that there is an obstacle and do not move it. I had to shut it down. I updated the software but it didn't fix it. I would be happy if you could help me with this.

I LIVE IN TURKEY . I BOUGHT THE DRONE FROM AMERICA. SO COULD SHIPPING AND WARRANTY BE A PROBLEM? COULD IT BE A SOFTWARE PROBLEM?

I agree with the poster as well. I have the same encounter with my mini 4. DJI rushed the release of mini 4 even with DJI assistance 2 there is NO vision calibration like mini 3 PRO

MAYBE THERE WILL BE AN UPDATE

With the DJI assistant 2 vision calibration should be fine. It's not the hardware issue. It just needs a calibration for that that's all. For now, what you can do is to off the obstacle detection mode and fly. That's what I'm doing temporarily till they get the update ASAP

Thank you for your response. Can you please confirm if you did experience an error message on the app during this issue? Please take a screenshot and send it to us so we can check. Thank you.

Hi there.Thank you for reaching out. Did your aircraft also experience a hard landing prior to this issue? Please let us know. Thank you.

Hmm. I would say yes. So I'm positive the vision could be calibrated via dji assistant 2 if that for mini 4 pro version is available in that app like the mini 3 pro and every now and them it automatically cut my mastershot or the normal flying mode as it detected an invisible object there but there aren't anything there at all sadly. So i hope with the vision calibration tool ready for mini 4 pro should be good

Thanks for posting!  I just purchased a “certified” one from a retailer, and noticed similar issues and odd alerts.  Perhaps same issue(s), and returning this one.  Hope you had your device repaired.

Hello there. Have you already returned your drone? The usual reasons for this issue are:
1Inaccurate vision system calibration or not calibrating the vision for a long period may cause an error in measurement distance.
2. When there is a point light source or strong light source (such as direct emitting or reflection from sunlight or fixed beam), the vision system may only check abnormal exposure and result in distance measurement failure. As such, the vision system may mistake that the obstacle is huge and close.
3. When the object checked by the vision system is an object with repeat textures, distance measurement failure may occur as well as mistaken obstacle detection. (Reason: The aircraft is not as intelligent as the human eye when measuring distances. What they see is a black-and-white view. The distance from the scene must be calculated from the algorithm. An object with repeated textures will affect the aircraft’s judgment of the distance from the scene and the capacity to build maps. As such, it may lead to mistaken obstacle detection.)
If you still have the drone and you are experiencing other errors, please don't hesitate to reach us. We are more than glad to help. Have a great day.

I had ghost obstacles while flying at 350 ft in open countryside. I turned the drone towards that direction to check, and it cleared the false detection. It didn't occur again.

Conditions were bright overcast with haze, no precipitation. Sensors were checked to be clean prior to flying.

It did not appear to affect the flight.

Mini 4 Pro.

I have the same problem. The device sees objects in the air that don't exist. This is a big problem and nobody can solve it. I can't use the main features of the Mini 4 pro because of this problem. Mini 4 pro should also be calibrated via DJI Assistant 2. DJI should fix this immediately. This is very annoying.

Hi, yasirr. We understand the inconvenience. I replied to you on this thread. We appreciate your patience.

Hi, Yes. Usually, it's just because of direct sunlight. Since the vision sensor is seeing black and white, it may not perceive obstacles properly during the occurrence. If you experience any more issues please don't hesitate to reach us. We appreciate your understanding.

Mine happened the same thing brother, you can't rely on the sensors, I crashed mine into electrical cables luckily no damage except the plastic hovers had to replace them,  bende dedim ki yaraya yedik, eh bu Drone ishde.

Hello, there. Sorry to hear about the mishap. I highly suggest that you send your aircraft for repair even if there's no severe damage. By doing so, you will ensure that your aircraft is in the best condition possible and that all potential damages are caught before they become a big factor problem. Furthermore, please be cautious with the flight environment and sensors may not work in certain conditions. You may refer to the screenshot below:

I had problems with no working obstacle sensors in my Mini 4 Pro. . I had changed the propellers to carbon fiber propellers (not original DJI). Since I changed the propellers my Mini 4 Pro disabled all sensors (and gave me the information that will be because I'm using propellers guard). But I'm not using guards. So, I removed the carbon fiber propellers and changed back to the originals DJI propellers. Obstacle sensors start to work fine since. . I'm wondering that the carbon fiber reflect light and the sensors seems to find that I'm using guards (and with guards the drone turn off the obstacle sensors).

Hello,
I also have the problem that the obstacle sensors detect obstacles at a flight altitude of 60m under the best conditions. All requirements described by DJI are met!

How can the obstacle sensors be calibrated?

My only option currently is to return the device. A pity.

I have the same issue: down sensor issue has appeared but i haven't crashed or hit with the drone to anything - it's my first day of using it. I restarted drone multiple times, update app, update flysafe, update firmware using dji assistance 2 and nothing has changed. I'm not able to use main feature of this drone.I'd say more - after one or two minutes since this error had appeared, drone has started to fly in different directions on his own. It's huge bug in this drone. Are Dji is going to fix it or shall I return this product and write the complaint?

Hi there. Sorry about the trouble. Are you getting any error messages? About the drifting issue, please try the steps below and see if it would help. Feel free to skip the steps already done.
1. Ensure that the aircraft mode is normal, i.e., the GPS signal is strong and the aircraft is in non-ATTI mode.
2. Check whether the device drift or unsteady hovering is within the hovering accuracy range, which is shown in the Specifications of the corresponding product on the DJI official website.
You can also post a video for us to check further, if possible.
3. Try flying to a different location and check if the issue will persist
4. Check the propellers and the state of the motors. Check whether any motor rotates abnormally when the propellers are not mounted.
5. Make sure that there is no magnetic interference. It is recommended to place the aircraft on level ground for IMU calibration and compass calibration.
6. Check whether the control stick is being pushed. If the stick movement is offset, the remote controller should be calibrated.
If the issue persists after the above methods have been used and the special scenarios below have been ruled out, please send the product back for further testing. We appreciate your patience and understanding.

Thanks for the answer. I was using mini 3 pro at the same place and haven't any issue within this location. I'll try to fly in different place, because this is the one element, which I haven't checked from attached list.

You are most welcome. Please keep us posted so we can help you further. Have a great day ahead.

Estou com mesmo problema no meu drone, os sensores quando ligo ficam apitando como se fosse bater e não tem nada em um raio de 500 metros para que ele possa bater, como comprei o meu Drone da China e moro no Brasil, agora estou à mercê da garantia, ele só voa com sensores desligados, mas a experiência do usuário que me disseram essa até o presente momento está sendo pessima, estou extremamente chateado, paguei caro no meu drone pra ter esse problema e dor de cabeça, e não sei como posso resolver! Fico aguardando um posicionamento da DJI global e suporte pra troca do meu equipamento ou concerto desse problema o quanto antes!

Why doesn't DJI release a software to calibrate the DJI Mini4Pro sensor like other models? Because I have the same experience, which is when it takes off and says it has encountered an obstacle.
