Why do emulators display responsiveness correctly, but phones - crookedly?

Question

css

In general, adapted the site . In emulators, everything looks as it should, as I did according to layouts. If you log in from your phone, there is adaptation, but it is too crooked, everything is stretched out, and, accordingly, the content area is small. I'm attaching screenshots. I can't figure out what the problem is. There is a viewport meta tag.

The question is closed. This is an outdated standard browser. Came from chrome - everything is fine. I also went from the standard Redmi 3 browser - everything works. I have a phone for more than 2 years, here is a standard browser and it shows off apparently.
