In addition to Bixby, the Samsung Galaxy S8 has also installed the language assistant "Google Assistant". This works, in contrast to Bixby, and can be activated as follows:
If you press the Home button for a long time, a white frame will appear around the current screen and the Assistant will appear. Here you must first agree to a data protection agreement and also release data for the application.
After that, the Google Assistant can be used on the Samsung Galaxy S8. Depending on the setting, there are two possibilities:
By voice command
Just speak from any screen "Ok Google" and then the voice command like "Tell me a joke"
By using the home button
Press and hold the Home button and the Wizard appears. Then speak the voice command. Currently, Google Assistant already understands many language commands related to navigation, contacts, weather, and other information.
As long as Bixby is not working properly, this language assistant is certainly a very good alternative.
