iPhone X Search language different than system language

[rproch]

I am using iPhone X with iOS 11.3.1.
The system was set up initially with Polish language as interface language. I've changed that to English and all the options in Settings are displayed in English.
However, I need to use Polish to search in Settings. For example if I search for 'Camera' I get zero results. I need to search for 'Aparat' (camera in Polish) - then the system finds and displays 'Camera' settings. All in English of course. I've hard restarted the device already.
Any ideas how to get search results in English?

Reset the phone and start all over setting up the language with english and polish region.

“Reset all settings” was enough. Luckily.
