Home page mode navigation (Landscape vs. Portrait)
While most of usability features have been designed to be similar between both portrait and landscape modes, the main difference is the gesture used to navigate between the different modes. In the landscape version, the scrolling gesture is vertical (up and down). In portrait mode it is horizontal (left and right).
Settings navigation (Landscape vs. Portrait)
Functions of the settings page remain the same with minor adjustments to fit the different screen sizes better.
