How can I use the Samsung Bixby application?

Step 2. Tap the Wake with "Hi, Bixby" switch to activate it.

              Now you can say "Hi, Bixby", and when the device emits a sound, start a conversation.

Teach Bixby

Swipe down on Bixby's response screen to see exactly what Bixby heard you say, as well as how Bixby interpreted what you said and came up with the results. If Bixby didn't interpret your request just right, you can make changes and help Bixby understand you better.

Bixby can write out your speech into messages or notes. Press and hold the Bixby key on your keyboard when it's open, then say aloud what you want Bixby to type in your chosen language.
