I cannot believe buttplugs have phones beat in this area.

This has been a feature on iOS for a long time—I’ve still got some custom patterns from back in high school

Like, distinctive vibration patterns.

Hmm, surely it's been done. It seems like straightforward good thing.

I'm sure Android (well, Samsung anyway) had this years ago... I remember it on my i7500 back in the 1.5 days.

I wonder when it went missing....

I have a different vibration pattern for my wife's calls and messages, work calls and messages, and all others. I swear I will get phantom vibrations from a specific set randomly.

there are, back from polyphonic times

I think nothing phones have it
