Questions

Why does this emoji look different on my phone?

Unicode standardises the meaning of a character, not its drawing. Apple, Google, Microsoft and Samsung each ship their own artwork, so the same code point changes shape between devices.

Does copying work everywhere?

The character is copied as plain text, so it pastes into any app that accepts text. If the receiving app has no font for it, you will see an empty box instead.
