Black Purple Premium Theme is a collection of stylish black themes designed for all Xperia devices running Android Kitkat and newer, including Android 7.0. The application does not require root access and changes the accent colors, home, top contact, dialer, navibar, and buttons. Virtually everything can be changed for Kitkat users as permitted by the theme engine.

The theme collection is technically done correctly, but the difference in various phone models can sometimes cause problems. The developer, Themes Catalog, has a Facebook group and Google+ community for support. They have tested the theme properly on phones without root and have requested that users have only installed stock software. It is important to note that the theme may not work when using applications like Xposed module or intervening in the application system.

In summary, Black Purple Premium Theme is a stylish and easy-to-use theme collection for Xperia devices that does not require root access. The support offered by the developer is commendable and the theme has been tested properly on phones without root.
