Mavic 4 Pro - Collision Detection false alarms?

[HaroldCal]

Greetings y'all,

This is my first drone with substantial collision avoidance capabilities, so forgive me if this is a noob question.

I am finding that when flying in N mode, the collision avoidance seems to false alarm a lot. Meaning, I have it up in the sky, nothing near it for 100ft in all directions, but it is still bonking at me. This seems to be more often from the rear sensor, but not exclusively. I thought it might have been detecting its own exhaust heat, and falsing due to that, as it seems to go away when I start moving forward. But it's not exclusively the rear sensor. Is this normal/expected behavior?

I've not used the Mavic 4 however on the Mavic 2 Pro the only time I've had problems with false alarms on the collision sensors is around sunset time or there's harsh light angles. At night time it warns the avoidance system isn't working which is correct but otherwise the system behaves as expected and only warns me of objects near the drone or stopping the drone when there is something near the drone.

I'll rescind this thread, as this prior one seems to cover exactly what I am seeing:

Mavic 4 Pro - Obstacle Avoidance Issues

Jun 17, 2025

So I received my Mavic 4 Pro yesterday. Upon flying for the first time, though, every time I hovered, the obstacle avoidance warnings would turn yellow and/or red in the back of the drone. As soon as I moved, it went away but would come back on after about 5 seconds of hovering. Since it was my first flight with the new drone, I didn’t fly far and I could see there were no obstacles (trees, birds, power poles, etc.) that should have been causing this. Never had this happen with previous drones, so not sure if there is a way to try to recalibrate the sensors, or if I should return it as...
