I porting the android 4.4.3 to our imx6 series boards,found this bug.
when I roate the screen to portrait
and hide the system navigate bar,the Activity tranform will return back landscape
2 frames at the time the animation started and finished, whitch cause the screen blinked 2 times.
I set the system animation speed 10 times slower and record the video.
Hi oyg,
Please take a look at the following thread and the explanation to the rotation:
