Sometimes comes a situations where having two different Facebook accounts on one device is simply easier than logging out and in again and again. For example handling your business’s social media account or just for any personal reasons,
Facebook does not include a native feature to manage separate accounts like Twitter does. But there is a simple method to sign into two different Facebook accounts at once on any Android device(Single Android Device).
Recently while using Facebook Lite, I soon realized that I was receiving duplicate notifications on my android device; one from the official Facebook app and one from Facebook Lite android app. Now it was clear that each app was running independently, which means that they could accept different login credentials.
Facebook Lite version is still not available on the Google Play Store in the United States, but you can still grab the Facebook Lite APK here. (Make sure “Unknown sources” is enabled on your device before trying to install it.)
And yes, you could also sign in with a different facebook account using web browser in your android device, but advantage of using two facebook apps is to have the advantage of getting notifications directly to your device for both accounts. Just sign into Facebook Lite like you do in Facebook app and enjoy the coexistence of both apps.
