This has been driving me insane for like three weeks now. Flying in normal mode, conditions are fine, no strong wind or anything, and randomly it just kicks into emergency brake and hovers. No obvious reason, I check the app logs and honestly I cant figure out what's triggering it. It's happened maybe four or five times now.

I thought maybe it was the obstacle sensing being oversensitive but I've gone into the settings and it doesnt seem like thats it, or at least I cant reproduce it by flying near objects deliberately. It almost feels like a signal thing but my RC is right there, maybe 30 meters away max when it happens.

Running the latest firmware, the one from like two months ago I think. Goggles v2. Haven't changed anything in my setup recently which is what makes this so annoying to diagnose

Check your propellers man, I had something similar a while back and it turned out one of my props had a tiny crack I hadn't noticed. The flight controller was probably detecting vibration anomalies and freaking out. Not saying thats definitely your issue but its worth ruling out before you go down the firmware rabbit hole.

Also worth pulling the full flight logs through the DJI assistant app rather than just looking at what the mobile app shows you, theres way more data in there and you might see something that points to what subsystem is triggering the brake.

I had a weird issue with mine for a while that turned out to be interference from a nearby wifi router when I was flying in my neighborhood. The FPV system on these is pretty robust but it can still get weird in certain RF environments. Probably not your problem if you're out in the open but worth mentioning I guess. Also which firmware exactly are you on because there was a version that had some brake sensitivity bugs that people were complaining about on reddit for a while
