The reason for this post is to help someone that owns a Mavic 2 that won't fly forward with the forward and rear sensors turnded on. I searched the internet for a solution to my problem, and wasn't able to find any post where someone else had experienced and resolved the issue that I was having.

To be more specific, when the drone was in P-Mode (which automatically activates the forward and rear sensors) it would falsely detect an object causing the drone to apply the air brake. The only way I could move forward, was to turn off the forward and rear sensors in the settings, or to put the drone in Sports-Mode, which did this automatically.

I believe the cause for this malfunction was the previous owner having crashed the drone into a wall while demonstrating to me how well the sensors worked. He made two mistakes: 1) He had the drone in Sports-Mode (which deactivates all of the sensors.) 2) It was dark out, for which reason the sensors would not have detected the wall had the drone been in P-Mode. What he didn't realize, is that the sensors don't work in the dark.

THE SOLUTION:

I had to install the DJI Assistant 2 specifically for the Mavic. VERY IMPORTANT: Make sure to download the application specifically for the Mavic as I downloaded the application labeled "DJI Assistant 2," which would freeze at the last step when calculating/calibrating the drone. The problem was solved after having installed the correct application, and running the calibration.

Thanks for sharing your experience with the drone, which would be very helpful to other customers who have the same problem. Enjoy flying.
