Currently the Light Phone II interface is only available in English.
You can receive and view text messages from a variety of languages/characters, similarly to what you'd expect from a smartphone, but for outgoing messages, there is an English QWERTY keyboard by default.
A user can access alternative characters by long pressing on a letter, i.e. "à, á, â, ä etc." and there are also settings for AZERTY and QZERTY layouts.
We plan to release a few alternate keyboards in the coming weeks, and eventually want to offer other languages for the entire OS. Thanks for understanding.
