I just put people’s names in my phone as their actual first and last name; if I call them something else I put that name in the nickname field.

Super basic “skill” to do this. 😒

Their name

I don’t have a significant other but my dad and my aunt each named their spouses “love of my life” in their phones

Full name with maiden name and a note that it’s my wife (in case I’m hit by a bus or something).

She’s twice in my phone. First is “1[name]”, second is “ICE”. ICE stands for In Case of Emrgency. It’s not really nescecary anymore, because android has a build-in emergency contact function now. It’s a remnant of a simpler time where nokia was still a prominent phone manufacturer.
