@Rhi same issue with mine and I have no auto cruise activated. I have previously brought this to YI attention via this forum. It appears to complete a 180 degrees to the right every 12-15 minutes. I have kind of got used to it but it can be annoying and I guess trying to sleep would be more difficult.
I assumed it was the camera ensuring it is still working but its frequency is annoying.
I have motion tracking activated but even with this disabled it still does it.
