What does Bixby do that Google Assistant can t?
Bixby offers similar functions but tends to be better at phone-related tasks like changing Bluetooth settings, optimizing the device (by clearing trash), or delivering news. You can perform online searches on Bixby too but the results won't be as good as Google Assistant.
Google Assistant is generally considered one of the best (if not the best) voice assistants in recognizing voice commands and performing actions. While Bixby is no slouch, it doesn't yet have the same level of accuracy and speed that Google Assistant provides. This is mainly obvious with online search functions.
