You already have one discussion on Bixby going here: https://forum.telus.com/t5/Mobility-Devices/Bixby-Update-schedule-S5/m-p/75675#M9239
Please note that you are on your own if you want to try get Bixby on an unsupported device. Google assistant is still more usable than Bixby since Bixby is still a work in progress.
