Last night I was flying around sunset - not far and not for long, I was just drawing down batteries before going on a trip. I was at about 25% battery and taking pictures of the sunset over the top of my house when all of a sudden I noticed the "fpv" display on my iPad mini was at a about a 20 degree angle (don't remember which direction). I thought to myself, well this is good that it happened while I was taking pictures since I'll have a better record of it (I was not recording the display unfortunately). I took another picture and when the simulated diaphragm opened up the view was level again! Later on when I looked at my pictures on my MBP they were all straight and level! I can't explain this one, unless it was so brief that it was between images and taking an image corrected it. Anyone else ever experience this?
