Why Samsung Galaxy devices Keypad (Numbers) doesnt have COMMA as decimal seperator?

[AC Question]

Why Samsung Galaxy devices Keypad (Numbers) doesnt have COMMA as decimal seperator?

In other Android devices, keypad for number type input fields in browser shows Decimal Separator based on User selected language. (COmma or DOT). Samsung devices seems to be not respecting USER Language CULTURE.

Let me know if I am wrong
