Facebook Messenger for Android 4.4.2 (KitKat) requires legacy app versions or the Lite variant, as current app versions mandate Android 5.0 or higher. Recommended options include installing older versions of Messenger Lite (v334+) or finding legacy full Messenger APKs (e.g., v410.0.0.17.85) from third-party repositories, along with using web-based alternatives to bypass compatibility restrictions. Detailed legacy app options and user discussions can be found at Operating systems that support the Messenger app - Facebook Version 5 (Lollipop) and above.
Do not download from random pop-up ads. Use established APK repositories that verify file signatures, such as: facebook messenger for android 44 2 apk
