Device Locale

Set device language and region for localization testing.

The default locale for Android is en_US . The default locale for iOS is currently en_GB but will be changing to en_US later in 2026.

Format

{language_code}_{COUNTRY_CODE}

• Language: ISO-639-1 (lowercase)

• Country: ISO-3166-1 (uppercase)

Usage

To set locale for the whole upload:

# German
dcd cloud ... --device-locale de_DE

# With device selection
dcd cloud ... --android-device pixel-6 --device-locale ja_JP

To override locale for a specific test, pass in the DeviceCloud env variable. This will override the upload setting above, but just for a single test:

# in your test.yaml
appId: my.app
env:
    DEVICECLOUD_OVERRIDE_DEVICE_LOCALE: de_DE
---
# test steps
