Features like what? I am curious since I have never had a Samsung device.
- Scroll screenshot to capture a long screenshot
- Automatically calling the displayed contact, call log or message by bringing the phone to your ear
- Rejecting a call by flipping your phone over
- Muting a call by placing your palm over the screen
- Waving your hand over the phone to wake the screen to check notifications
- Having your phone alert you of missed calls/messages by vibrating after you pick it up after it's been face down
- Pressing the home button 3 times to shrink the screen for one handed operation
- Fine tuning audio output with a tone test
- Smart stay to keep your phone screen on while you're looking at it
There's probably a bunch more features buried into the settings all over the place that I've forgotten or haven't discovered yet. I know most of these things can be accomplished on any phone with root and/or 3rd party apps, but the integrations is kind of nice when it's built into the phone's ROM.
