This refers to a modified application package (APK) of the Facebook application. The designation “dark” typically suggests a user interface with a darker color scheme, intended to reduce eye strain or conserve battery power on devices with OLED or AMOLED screens. The numbers “v141 rev 2” indicate a specific version and revision number of this unofficial modification, signifying a particular build within the development cycle. These modifications are generally created and distributed by third-party developers, not Facebook itself.
The appeal of these modifications often lies in the enhanced customization options they offer compared to the official application. Users may seek them for the aesthetic preference of a dark theme, improved privacy features (though these claims should be approached with caution), or the removal of unwanted features present in the standard Facebook app. Historically, such modifications have emerged to address user desires for features that the official application lacks or to provide a more streamlined user experience. However, it is crucial to acknowledge that downloading and installing such applications carries inherent security risks.
