The number of languages that are supported natively on Android is being increased with every released, but can vary between manufacturers. When we get a new device in, we’ll always try to offer a post that runs through the system languages that are supported on the device. If you’re language isn’t included as standard, we suggest installing an app called MoreLocale2, which doesn’t change the system language completely for all but is very good in most cases.
We’ve just been made aware in the comments on our One X languages post (thanks, gebaly) of an app called Multiling keyboard, which has good reviews on the Play Store and supports a huge list of languages. It also offers predictive texting, so is a must if you do wish to type in a language that is not supported by the device, or need to switch between typing in different languages. The video below shows some of the languages that are supported.
