Unreal! I went out and bought a P4 while I wait for Mavic(6 weeks now)....First time  starting P4(after removing both gimbal protectors) gimbal error, gimbal  was moving all around.... ....did all the  calibration....looked online says to send into DJI(yeah right)....repacked......no  need to spend more time with that problem... heading to store to return  it......HOLY!!! SMOKES!!! Can you say lemon!

I am beginning to see that DJI has some serious issues and they are deeper than we think!

It may have been jumbled around during transit at some point. It's good that you were able to catch it and have it addressed with your dealer.
