It seems I'm not alone; I've read lot around the web about this bug. Here is a video accelerated 20x. It make Osmo+ allmost unusable to make Time Lapses !
Yes, I've made two real life tests, one with Motion TimeLapse, and one with Regular TimeLapse.
Here is the Regular TimaLapse : You can see the Drift bug :
Here is the Motion TimeLapse : No Drift bug ?!
Well: this bug definitely exists here. And appart TimeLapses, if you want to make a simple fixe video shot, the bug exists... Sometime a very visible Yaw drift at the start of a shot.
Can our confirm my tests with your Osmo+ ?
I'm just commenting to keep in touch with this thread. I just got my Osmo+ about a week ago. I haven't been able to go out and film with it or test out all the functions yet. But hopefully DJI gets this fixed for ya. Do you think this is happening to all/most units (I have been seeing posts about this too)? I wonder if it's strictly due to firmware, or if there's physical wear and tear you don't see after using it for some time? I hope mine is fine and doesn't turn that way anytime soon.
