Upgrading from Android 4.4.2 (KitKat) to Android 9.0 (Pie) is a significant jump across five major generations of software. Because Android 4.4.2 is no longer supported by Google, an official over-the-air (OTA) update to version 9.0 is highly unlikely for devices from that era. Methods for Upgrading 1.

While improbable for a device as old as version 4.4.2, always check for official updates provided by your manufacturer: Navigate to Settings > About Phone. Select System Update or Check for Updates.
