Samsung says with its artificial intelligence Bixby "Don't be afraid to eat like a local. Bixby Vision will translate the menu for you so you can order exactly what you wanted.".
Samsung had one special app called as S-Translator in the Galaxy 4 and 5 phones. where the user can get much translation benefit from the unit. Their translation App knows 9 different languages with different fonts in these devices.
There is plenty of translation app although this pre installed app is designed to translate the emails of the user with little maneuvering. Also it can do speech to text and text to speech perfectly. The built in app can also translate printed text too in to the user's language.
