Telegram supports Android 4.4.2 via their legacy APK.

Facebook Messenger was initially introduced as a chat feature within the main Facebook app. However, the standalone app quickly gained popularity, and by 2014, it had become a major player in the messaging space. The app's popularity can be attributed to its ease of use, feature-rich interface, and seamless integration with Facebook's social network.

Facebook officially dropped support for Android 4.4 (KitKat) several years ago. If you visit the Google Play Store on a KitKat device today, you will likely see a message stating, "Your device isn't compatible with this version." This is not because your device is broken; it is because the coding language used to build the modern Messenger app requires a newer Android framework (usually Android 5.0 Lollipop or higher).
