The way to achieve this is simply by logging out Facebook Messenger. Sounds easy, but it is not because we no longer appears that option. Therefore, we have to follow these steps.
•First close the application, in case it was open, and delete it from your list of recent applications.
•In Settings -> Applications (or Applications Administador ) seeks to Facebook Messenger. Click on it and select Clear data.
•Finally, we just have to uninstall the application.
At this point, the method is the same. We just have to open Facebook and go to the chat. At that time, the application will tell us that it is mandatory that we install Facebook Messenger. We use the option that the implementation provides us and leads us to Google Play Store. From the app store click on Install and now comes the trick. Before the download is finished, cancel it. To do this, we just have to click on the "X" from the same window of Google Play Store. Very easy!
