I have a S8 Plus, carry my phone in my back pocket.
Bixby gets hit at least 10 times a day.
Hear somebody talking and forget its my dang phone.
Bixby calls people. And i get texts from the carrier about how many minutes used.
I have turned Bixby off and disabled the button.
And had Verizon to do the same thing.
Bixby does a update and reinstalls itself.
I'm back to start again.
For now, give them a few days, weeks, and they'll have an "issue" & it won't work anymore. Just change the setting for free & don't push the button twice.
