What is triaxial leveling?

[jax_maxit]

Yes, I Googled. Unfortunately the only hits I got are phone specs, and no links explain what it is - just that smartphone cameras have the feature. Most search results either define triaxial or leveling.
Can anyone please explain to me what triaxial leveling is, with regards to smartphone cameras (or any cameras)? What is supposed to happen when you enable the feature??

What is supposed to happen when you enable the feature??

Have you tried enabling it?

Just guessing from the name you'd probably get a leveling meter that pivots around multiple axis for leveling your shot in more than one direction.

Well, I'd be guessing that image stabilisation occurs on three axes: up/down, left/right and forwards/backwards. I guess this might be handy if you're shooting at an extremely narrow depth of field and your subject moves closer or further away from you after focusing? Didn't know that existed though, lol

EDIT: just realised this makes sense for a camera tripod system, where your third axis is your degree of tilt.
