Android4.0 rotate 180 by default on the interface. The recently used program view is displayed on the inverted view.

After the system rotates for 180 degrees by default, click the recently used program in the status bar and find that the view is still inverted. The trace code is modified as follows:

<Bool name ="Config_recents_thumbnail_image_fits_to_xy">False</Bool>

}

}

Android 180 is rotated by default on the page.
