I'm still running the June 2018 firmware. None of these problems here.

I'm running the latest or probably the last updates which were available around October/November 2019 and the only issue I;m having is with the occasional camera view on my tablet or phone turning upside down which is not a new issue, I had this from around February 2018, but before October 2019 I was avoiding updates for little more than a year.

This thread is almost three years old. I need a discussion about the most recent updates.  Both my P4P's have yaw drift now. It sucks for photography.  Only happens since the update.  All calibrations are done.
