The Dark Os Orange Theme is a professionally designed theme with an icon pack for Xperia devices that run on Android KitKat and newer. This theme does not require root and features a dark blue home, top contact theme accent, navy blue dialer, dark navy blue navigation and status bar, OS style navigation buttons style, OS style buttons, and OS style volume control. Additionally, it includes icons pack for the XPERIA home launcher, 2 clock widgets, clock widget in lockscreen, and a themed keyboard.

The instructions on how to set up the icon pack are available on the developer's website. It is important to note that this theme does not support Z1 Firmware. The developer, Michał Ambroziak, has made all the files, wallpapers, and icons himself and has all the rights to them. The theme has been tested and works properly on phones without root. However, themes are technically done correctly, but the difference in various phone models can sometimes cause problems. If you encounter any problems with the theme, please send them to the developer on Google+.
