The user wants to detect does her application used on Android device (Nexus 6.0/7.0) with Hebrew installed as a device's display language or not. This can be achieved with this call QLocale::system().uiLanguages().at(0). For majority of different locales the user is getting a right information: country code and language code. however for Hebrew the user is getting this information:

m_country_id = 0 (QLocale::AnyCountry)
m_language_id = 1 (The "C" locale is identical in behavior to English/UnitedStates.)
m_currency_iso_code = "\0"

The developer can see this problem if the demo attached is used and the Android device's display language is set to Hebrew.
