At least for me when I rotate the screen of my android; I do get a rotation, but it looks like the original image is rotated on the screen - but its dimensions are not altered: so I get a black / white region at the top and bottom and part of the image cropped off the right-hand side (when going from landscape to portrait) ;-) Rather a problem - particularly for phones.
Kendy fixed this in master - thanks dudie ! =)
