The Galaxy S6 Edge comes with a useful feature called Information stream that allows you to view quick tidbits of info with a quick back-and-forth swipe on the edge of your display while the screen is off. Apparently, Samsung left the door open for third-party plugins to use this feature, and now we're starting to see an influx of useful additions.
Developer trailblazer101 might just have the most useful Information stream add-on yet. It allows you to control music playback without having to fully wake your device, and it's pretty simple to install, too. Just make sure you have "Unknown sources" enabled in your phone's Settings under "Lock screen and security" before you begin.
This particular Information stream feed is not available on the Google Play Store, so it will have to be sideloaded. To begin, point your phone's web browser to this link, and the file will start downloading automatically.
When that's finished, tap the "Download complete" notification to launch the file. From here, press "Install," and when that's finished, tap "Done."
With the new Information stream feed installed, you'll have to enable its notification listener service next. So head to your phone's Settings menu to select "Lock screen and security," then scroll down and tap the "Other security settings" option.
Next, scroll down again and tap "Notification access," then tap the "MusicPlayer Cocktail Feed" entry and press "OK" on the popup.
With that taken care of, it's time to activate the new feed. Head back to your phone's main Settings menu, then select the "Edge screen" option to begin. On the next page, scroll down a bit and tap the "Information stream" option, then make sure the feature is turned on and select "Manage feeds."
On the next screen, scroll all the way to the right to find the newly-installed feed. From here, tick the box at the top of this entry to activate it.
This Information stream feed should be compatible with any music player app, so start playing some music, then turn your screen off. From here, swipe back and forth on the right edge of your display, then swipe to the right to see your music player controls.
What are some situations where you've found this feature to be more handy than the regular lock screen music controls? For more Information stream hacks, check out our other guides on launching apps when the screen is off and adding a battery meter and system stats to the stream.
