As S6 owner, I found some good feats that comes on the S6 by default which I love since I don't need additional apps to get the same results.

IMO, here are my favs 5:

1. Cam Pro mode: If you love photography, you can try and play around with this built-in options.

2. Private mode (control panel): You can hide gallery and info w/no need of any other app. You can setup your passcode.

3. Samsung Pass: Great feat to have access to apps and accounts with your fingerprints (Lastpass works better, though.)

4. Selective Focus: Shoot like a pro with one of the greatest mobile phones and get the so-wanted Bokeh effect!

5. Slow motion: The S6 cam has a lot of good built-in feats into the cam settings. Slow Motion is one of my favs.

I know there's a few more feats not listed like split screen, mini apps, easy mode , etc.

Please share! What's your top 5 ?
