I can compensate the horizon line with the gimbal roll, but I need to do it many times. I did not need to do this in my P3P. Is there something else to do, besides the Gimbal and IMU calibration procedures? have done twice already.

Same here,
Its going back to DJI for warranty.

I assume you contacted support and they told you to send it in? I have this problem mid way through flying as well.

Same issue here....I'm watching videos from others and it seems this is an issue affecting a LOT of Phantom 4's. I highly doubt they are all defective, my guess is this is software related.....VERY frustrating!! I purchased through Apple. I could try exchanging it, but my guess is the exact same issue will be there....

I have not yet. Waiting for firmware or more tests...don't want yet  to go thru the DJI repair process....one week to go..one week there ( if lucky) ...one week to come back...it means around one month w/o bird.

I exchanged mine at the Apple Store today. Unfortunately it's raining right now and the sun is about to set, so I can't confirm if it is a hardware or software issue.  I will fly tomorrow (weather permitting) and let you guys know what I find out!
