Ever get an important email that's at least partly written in Spanish or contains Chinese characters? Samsung's S Translator will convert emails, SMS messages and ChatON IMs from 9 different languages to English (or your native tongue).
Walking down the street and need to ask directions from someone who doesn't speak your language? Like Google Translate, S Translator can convert voice input too, allowing you to hold a helpful but awkward conversation where you hold the phone up to your mouth, talk and then play the translation for the other person. LG's QTranslator is a little more robust as it uses the camera to translate foreign language text in real-time and offline.
