Nothing is mentioned but I noticed one which is a QR scanner directly from the camera app.

Hi, try resetting your device.

One of the best if not the best out there.

It is a voice assistant. You can ask Bixby to do some tasks on your phone like changing phone settings, setting reminders and also do some search as well (although Google Assistant is much better for search)
