Theming issue on mobile device: narrow screen width [#2191671]

On a mobile browser or desktop when horizontal screen resolution is approx 320px I noted horizontal scrolling available.
The default Commons installation is also affected. Screenshots attached.
The issue resulted in a mobile browser opens a page than page doesn't fill a full device screen.

Any ideas will be very appreciate.

There is also another CSS issue related to Main menu and Browsing Widget.
Here are two screenshots attached below, one made on Symbian OS and other one belongs to Android Browser.

Meanwhile, there are no similar issues on Apple devices. iPad and iPhone both successfully pass test.
PS. Regarding the search button align I have no idea. It displays well on iOS devices and desktop browser in narrow mode but Android Browser breaks aligning
