Set Locale and Language
Put the Language Switcher widget on your home screen and just touch it to switch languages.
Select the languages you will most commonly need to switch between. Choose from over 50+ languages!

As we know that some rom of Android have no full set of language,sometimes it is hard to set the language you want in your phone.Or if the custom locale function in menu don't support your language,you can try this app!
You can select more locales via this app.This app will tell you what language is supported in your
cellphone, you can set this language by just one click!

If your device doesn't support the language (locale) that you want to use, you can set it with this application, and then other applications will work with the selected language (locale).
Note: Selected language is used only if the application is localized!
There are languages, which are missing from the list. The reason is, that I haven't found much localizations for those languages.
