Tap the ring twice to activate Bluetooth and other sundry things the ring can do

What else can you do to operate the ring?
-bump it flat when near depleted: extra 5% power
-scratch it with pocket knife (or in car accident): bring out your holo
-backup your soul (not clear)
-verbal: activate sentry mode / search and destroy for your holo

Probably auto sizes to your hand if you twist it or something

Lots of other ways maybe you can interact with the ring, some of them not safe for Reddit. Anyone have any ideas?

Will Hal's holo have nice things to say about John (updated right before his death) when it comes back at the end of the season for a tearful farewell to John and fans? Just guessing.
