The Facebook app for Android 5.1 (Lollipop) has become a rare necessity for users maintaining older hardware. As mobile operating systems evolve, official support for legacy versions often fades, forcing users to seek specific APK files to maintain social connectivity. The version requested, likely an older stable build or a specific branch like Facebook Lite, represents a bridge for devices that lack the processing power or system architecture to run the modern, resource-heavy Facebook "Katana" application.
Maintaining an older device on Android 5.1 presents significant hurdles, primarily because modern apps demand higher API levels (typically Android 6.0 or higher for the main Facebook app [23]). For users on Lollipop, the standard Google Play Store may not offer a compatible version, leading to the use of "sideloading"—the manual installation of an APK file. This process requires users to enable "Install from Unknown Sources" in their security settings [14]. While this offers a solution for older hardware, it introduces risks; users must rely on reputable repositories like APKMirror or Uptodown to avoid malware-laden files [5.2, 5.7].
For optimal performance on Android 5.1, many experts recommend Facebook Lite over the full application. Facebook Lite is specifically engineered to function on slower networks and older Android versions, supporting systems as far back as Android 4.0 [31]. It uses significantly less RAM and storage—often under 2MB compared to the hundreds of megabytes required by the standard app—making it the most stable choice for a 5.1 environment [13, 17].
Ultimately, using Facebook on Android 5.1 is a exercise in digital preservation. Whether through a specific legacy APK or the streamlined Lite version, users can extend the life of their devices. However, they must balance this utility with the security implications of using outdated software that no longer receives critical patches.

The phrase "facebook para android 5.1 9 apk" translates from Spanish to "Facebook for Android 5.1.9 APK." In technical terms, this refers to the installation file (APK – Android Package Kit) of the Facebook application that is compatible with Android version 5.1 (API level 22) and specifically optimized for build version 5.1.9 of the operating system.
As of 2025, Facebook has officially dropped support for Android 5.0 and 5.1 in its latest releases (v400+).

Our final recommendation: Do not install the full Facebook APK on Android 5.1.9. Instead, install Facebook Lite. It gives you 90% of the functionality, uses 10% of the resources, and will continue to receive updates for the foreseeable future. If you absolutely need the full app, target version Facebook 290.0.0.23.105 (armv7a) and accept that it will be slow.
Remember: performance and security should always come before convenience. Browse safely, keep your data backed up, and consider moving to a newer device or custom ROM for the best Facebook experience.
