Downloading the Facebook app for your Android is great, it brings all your favourite features like Facebook Chat, your Events calendar, who's Nearby not mention that all important News Feed to your Android phone or tablet.
But for all its plus points, Facebook has made logging out of the app a nightmare for some reason. Every person I have leant my Samsung Galaxy Tab 10.1 to has asked me the question 'how do I log out of Facebook?'
Here's how it's done.
First of all (no matter where you are in the app) click on the top left corner where is says Facebook or the title of the page you are in i.e. News Feed.
From here you will get back to the app's home screen. Now you have to touch the three horizontal lines located in the Android dock, this can be found at the bottom of the screen.
As you can probably see by now there is a log out button on the right hand side of the new box you've just brought up. Simply click on that and you will be logged out of Facebook straight away.
