Is it possible to set the language and locale to different values? I'd like to have all the text displayed in English (US), but use the Polish (Poland) formatting for numbers, dates etc. On a desktop Linux system, I'd set LANG to pl_PL and LC_MESSAGES to en_US. Is there a way to so on Android? I see only combined language+locale setting. Note: I am not asking about the keyboard, I know can set it to use a language different from the language+locale setting without problems.
I've set my phone to English (United States), but then I also customized Date &amp; Time to use Italian format (DD/MM/YYYY). Numbers don't seem to be customizable, plus some apps ignore Date &amp; Time settings and use the ones from the main language, or allow to specify a format.
