Android System Locale

When the board leaves the factory, the default locale of the pre-installed Android system might be English. To set it to another locale, follow the instructions in this section to specify the device's default locale setting.

AllWinner Configure Default Locale

1. persist.sys.locale is a persistent system property. Setting it to zh-CN will make the system use Chinese (Mainland China) as the default language and region configuration.

vim device/softwinner/apollo/apollo_p2.mk
    PRODUCT_PROPERTY_OVERRIDES += \
        persist.sys.locale=zh-CN

!!! Note In the original configuration, persist.sys.country=US and persist.sys.language=en indicate the default country is the United States (US) and the default language is English (en).
After modification, persist.sys.country=CN and persist.sys.language=zh change the default country to China (CN) and the default language to Chinese (zh).
