1. Pick a side, any side – which Edge is best?

The first thing to know about the Edge display is that you can only use one edge at a time. The features you can enable, like people Edge or Information Stream do not work on both sides simultaneously, or switch sides like your display does when you rotate your phone.
If you're a leftie, the left-hand side is probably best for you and vice versa for righties – but either side works the same. Just go to Settings > Edge Screen > Edge Screen Position.

2. Color-code your friends and keep them close

This is perhaps the coolest feature of the S6 Edge in my mind: first, assign a color to your favorite contacts (in People Edge) which transforms into a color-coded glow from your phone when they call (Edge Lighting).
People Edge also provides a quick access list of your favorite people right on the side of your screen – you'll see the little white bar on the Edge display once enabled – and show colored lines when you've missed a call or message from one of your besties. Swiping that line out will provide a summary of what you missed with the ability to respond immediately. Go to Settings > Edge Screen > People Edge

3. Reject calls with a finger and send auto-responses

This is a sub-section of the Edge Lighting feature (whereby you'll see a color-coded light emanating from the Edge display when your phone is placed face down and a selected contact tries to reach you).
If a contact tries to reach you and you're busy, you can simply place a finger over the heart-rate monitor to reject the call and send a pre-defined message automatically. A very handy way to know who is calling you and deal with them discreetly if you can't talk.

4. Manage your Edge notifications

Once you've set up your People Edge contacts, the next thing to do is decide if you want to see all missed communications from them or only some. In the Edge screen settings you can decide to enable Email, Missed Calls and Messages. At present there is no option for other apps, but we're sure that feature is coming.
Go to Settings > Edge Screen > Select Notifications and check the boxes next to those notification types that you'd like to see appear in your People Edge notifications.

5. Get useful information on the Edge

The Edge screen can also be sued as a news ticker, which Samsung calls information Stream. This is because there's a lot more to it than just a Flipboard feed. You can also get weather updates, sports scores, Twitter feeds, notifications and more via downloadable Edge content.
Just got to Settings > Edge Screen > Information Screen and flip the switch to enable Information Stream. You'll now be able to tap Manage Feeds to select and rearrange the feeds you want on the Edge display.

6. Throw away your bedside clock – use Night Clock instead

One great feature of the Galaxy S6 Edge's AMOLED display is that it is incredibly power-efficient. AMOLED displays only light up individual pixels, so a mostly black screen with a few illuminated pixels draws very little power.
Go to Settings > Edge Screen > Night Clock to flip the switch and enable it. Now, when your screen is dimmed, you will see a gently glowing time and date combo on the Edge display, meaning you don't need to turn your phone's screen on just to check the time.

7. Theme your Galaxy S6 Edge

The new Galaxies also come with Samsung's theme engine. With the tap of a button you can completely change the look and feel of your S6 Edge with a range of pre-loaded themes or others which you can download.
Go to Settings > Themes to choose from the three pre-loaded themes or tap the Store button in the top right to launch the Theme Store app for a variety of alternative themes, with new themes added every week.

8. Change your interface font

The Galaxy S6 Edge also lets you customize the font in which your interface appears. Go to Settings > Display > Font Size to see the pre-loaded fonts, or scroll down and tap Download Fonts to see a variety of alternatives, some free, some paid, that will add some flair to your device.

9. Conserve your battery

The Galaxy S6 Edge has both of Samsung's excellent battery-saving options: power-saving mode and ultra power-saving mode. The first simply limits your CPU, minimizes haptic feedback, screen brightness and shortens the amount of time it takes for your screen to dim when a notification comes in.
Ultra power-saving mode is more for emergencies. It turns your display gray scale, limits the number of apps you can use (which you can choose yourself) and shuts down all but the most important functions of your phone. It's not much fun, but it's great when your battery is critically low. Go to Settings > battery to enable either mode.

10. Manage your home screens

If you're the kind of Android user that simply accepts the home screen setup that Samsung gives you – complete with Galaxy Gifts widget and all – then this one is for you. Long press a blank spot on a home screen to see the home screen manager.
You can rearrange your home screens, add widgets, change the grid layout of app icons, remove Flipboard Briefing (by un-checking the box at the top) and change your wallpaper. You also have quick access to your Themes from here.
