Regarding supported languages on devices supporting the SmartSDK: The SmartOp Panel has a carrousel of languages which you can select (about 5) to set the device language. The SmartOp Panel supports a lot more than 5 and you can choose the five that get set by watching the video above. There are support for other languages and if you don't see yours on your device, please reach out to us and let us know which are missing.
