BlackLollipop - Red Theme is a personalization application designed for all Xperia devices running Android Kitkat and newer, including Android 7.0. The theme collection is designed by Michał Ambroziak and does not require root access. The application changes the accent and primary colors of the phone, including a black navigation and status bar for Kitkat.

The theme has been tested and works properly on phones without root access. However, users may experience problems due to differences in various phone models. In such cases, users can contact the developer via Google+. It is important to note that the theme may not work when using applications such as Xposed module or intervening in the application system.

Users are advised not to use any part of the application without the developer's permission as all files, wallpapers, and icons are self-made and owned by the developer.
