I have a Nexus 5 with Kitkat 4.4.2 and have the Hangouts app as the SMS app. My friend has an Samsung Galaxy S Relay and also uses Hangouts app as SMS app. Whenever we send SMS to each other with emoticons, emoticons are not converted, instead we just see the text code for it. I'm baffled by this since we're using the same app for texting. I'd understand if it was like from an iPhone to Android, or something like that. Any idea what could be causing this and how to fix it?
