After a recent update, the Facebook app for Android, the widget is no longer available. Many users are not pleased about this. You can bring it back by installing an older version of Facebook with these steps.
- Go to “Settings” > “Apps” > “Facebook” and select “Uninstall” to remove the app.
- Open a web browser on your Android, and go to this link, and download version 184.108.40.206.81 beta of the Facebook app. If you receive a parsing file error, try a lower version like 220.127.116.11.77.
- When prompted, open the file. You may have to swipe down the notification area, tap the download, then choose “Open“.
Note: You may have to change a setting under “Settings” > “Security” > “Unknown sources” to install the file.
- Walk through the install.
Now you should be able to add the Facebook widget back to the Home screen. Let me know if you have questions in the comments section.
