I'm not the most tech savvy Samsung user and it's likely been obvious on here at times. I want my phone to be able to make/take calls as well as take nice pics. Of which all I can do. But I've noticed when I get a phone call it says BIXBY something in the center which I've always ignored. What would happen if I push this? I've not taken the time at all to see what Bixby is all about with this phone or the S-21-U I had before.
