How can I get rid of Bixby on a Samsung S8+ as this rubbish is driving me crazy? Samsung needs to remove this useless piece of nonsense from its products!
Go to settings -> apps. Then select the three dots and choose show system apps. Then go down the list and disable/force stop/clear data/deselect auto-update (by searching for the app on Galaxy Store/Play Store, then clicking three dots) each and EVERY Bixby App & Service. Good luck 😉
Thankfully on the newer phones you can completely remove the function of Bixby from the power button (they removed the Bixby button) and never have to deal with that again. For the s8, you are best off looking at the guide another user sent in reply to this post
