• A screen’s orientation can change as the user turns the device
• When the user turns the device from vertical to horizontal
orientation, the layout or view reorganizes
• Interface elements that are in the vertical orientation may
become inaccessible in the horizontal orientation
• Scrolling can be implemented to alleviate some of the
problems associated with orientation change
• If scrolling cannot make it work, as a last resort fixing the app
to work in only one orientation
