How can I select my phone's language?
In many countries, you can select a language for your phone from a selection of a few languages. Furthermore, for many phone models, your phone actually has two language settings:


Phone language: the language used for display texts on your phone
Writing language: the language used by the dictionary for predictive text input

Both are usually accessible from the Settings menu, under Phone Settings or General Settings. Model-specific instructions for setting your language preferences are available in your user guide.

Please note:
The languages available in your phone are built in.
If you change the phone language, you must restart your phone in order for the change to take effect.
If you select Automatic, the phone selects the language according to the information on your SIM card.
