Bixby button

I also used Package Disabler Pro to disable all Bixby items. After a recent update on T-Mobile that included Bixby updates, I re-enabled, checked out the changes, determined it was still no more useful than Google Now and disabled it again. Not sure when Samsung will launch voice support. I'll try that too, but unless it really allows me to both launch apps and control what they do, as promised by Samsung, I'll disable it again. I find the number of assistants on the market already more than necessary. Google Now works very well. Cortana also does, but I don't need both. Siri is pretty bad compared to any of them. I had Alexa on my Mate 9. I don't think Alexa really makes a ton of sense on a phone.

Bixby will be better than Google Assistant. It'll actually do what you say, vs. limited Google Assistant.
