Wait, I should check if there's actually an official APK for Facebook called "Espacio." Maybe the user made a typo or is referring to Facebook Spaces, which is a VR feature. If that's the case, then Facebook Spaces isn't compatible with Android 4.4.2. So maybe the user is looking for a way to access Facebook Spaces on an old phone which isn't possible. I need to verify if there's an official ESPACIO APK or if it's a misunderstanding.
