Not the same likes. At some point Facebook added a &quot;like&quot; button in the Messenger, which immediately sends a slightly-different thumbs-up. On Android it replaces the &quot;send message&quot; button when you haven&#x27;t entered any text yet, and it also features as an action if you expand the new message notification. Both of these make it super-convenient to use it.<p>(Though personally, I don&#x27;t use it at all; a thumbs-up icon feels disrespectful for me, I prefer to acknowledge by typing out &quot;OK&quot; or even a smiley.)
