Android operating system is the most flexible mobile operating system. This operating system is based on Linux and can be easily installed and used on any type of hardware. In addition, Android is released as open source, meaning that everyone can view and even use its codes. Anyone with the necessary knowledge can modify Android codes and create a completely different operating system. This has become the basis for creating various custom ROMs. Custom ROMs are edited versions of Android that are offered for different phone models and brands by various teams. Cyanogen was one of the most popular and widely used custom ROMs for years, but unfortunately its development was stopped. However, some developers decided to create the high customization feature of Cyanogen on all Android devices. Their efforts led to the creation of the Substratum theme engine. This theme engine allows the user to apply their desired theme on all parts of the Android interface. The applied themes even affect the notification panel, quick settings, app menu, home screen, and so on, giving the phone a unique and personalized appearance. Fortunately, many themes have been made for this theme engine, and we have offered a large number of them on Usroid. Today, we are also offering another beautiful theme, Biohazard Substratum Theme, which is a very beautiful theme for the Substratum theme engine, specifically designed for the Android operating system and developed by pierx. It is available on Google Play for $1.99. Biohazard refers to dangerous chemicals. A special symbol is used for this type of material, which has been used extensively in this theme. This theme has the ability to apply a background image on all parts of Android, and a suitable background image is included with the theme and applied on the phone. Note that this theme cannot be used independently and separately, and you must have the Substratum app installed on your phone to use it. Root access is also required to use this app. If you are interested in a dark user interface and want to experience a new user interface on your phone, we recommend this theme to you.
