This is too good. I knew Samsung could not pull off a flawless launch.
Could you imagine Apple releasing a device with a non-working button? That would never happen.
A few things with your comment. I'm not buying the S8+ because of Bixby and many Android enthusiasts were left scratching their heads on why Samsung would release yet another voice assistant because Android already has Google assistant. This news is actually good and maybe Samsung will come to their senses and allow the button to be remapped natively and drop that stupid Bixby altogether. And because I also own a iPhone 7 Plus I do remember that the portrait feature was delayed after phone release. Apple just gave us the curtesy upfront. And finally the button is still functional if you've played with a demo unit. A short press brings up the Bixby cards and a long is what brings up the Bixby assistant (the feature that's being delayed.
So in all honesty I pray that Samsung drops it all together. No one yet has called it a good idea or must have feature. I wouldn't mind remapping that button as a camera button or something else more useful. And from what I'm hearing the button can be remapped with a third party app.
