If you are holding onto a reliable older device running Android 4.4.2 (KitKat), you have likely discovered that the modern Facebook app is no longer compatible with your system. Updates have made the current version of Facebook too heavy and demanding for older hardware, often resulting in crashes, lag, or an "Incompatible" error on the Google Play Store.

Android 4.4.2 KitKat was released in 2013. The modern Facebook app requires a much higher Android version and hardware specs that cause older phones to freeze, crash, or run out of memory.
