The smartphone screen is weird after upgrading to version 8.15.13 after using version 8.15.6?

Version 8.15.6 is available on smartphones, but version 8.15.13 is only available in portrait mode

Hi there, where can I download this app?

There was a change to a more logical width for the dashboard grid. The behavior in your screenshots is not typical of changing the width and is likely a different issue. My only suggestion is to just resize the widgets to their previous dimensions and positions.
