Delete unwanted Facebook comments using the Android app
You no longer have to rely on the Web site to delete comments on Facebook.
You can now moderate the comments on your own Facebook posts from your Android device. With an update to the Android app last week, Facebook enabled the ability for Android users to delete comments in just a few short steps.
The next time someone leaves an inappropriate comment, or an old flame starts proclaiming his undying love for you, you'll be able to delete the comment without having to rush to a computer.
The first thing you'll need to do is update to the latest version of Facebook for Android. After you've updated, you'll need to wait for an inappropriate comment. Or you could test the process of deleting a comment on any of your posts; ensuring you're ready to spring into action.
Tap on the comment you'd like to banish from Facebook and you'll see a pop-up asking if you want to delete the comment, or cancel. Tap on delete and the comment will disappear, never to be seen again.
