A cool, hidden feature called Daydream in Android turns your phone’s display into a mosaic of images, news headlines or random colors. Debuting as part of Android 4.2, Daydream remains a feature in Android Marshmallow, as an interactive screensaver that switches on when you plug in your phone — so long as you've enabled it.
Here’s how to get Daydream working and turn your phone into a vacation picture slideshow or just make things more interesting when you’re charging up your device.
1. Open Settings by swiping down from the top of the screen with two fingers or swiping down once and touching the top bar.
2. Tap Display.
3. Tap Daydream to see a list of apps that integrate with Daydream.
Daydream's default option is Clock. To see what it looks like, touch the overflow button (three vertical dots at the top) and select Start Now. You end the Daydream session by tapping your phone's screen.
Here's how to access more customization options.
1. Touch the overflow button, followed by the When to Daydream option that appears.
2. Set the Daydream to begin when the device is docked, charging or either one.
You can also select which of your photos to display in a Daydream session. Here's how.
1. Select Photos from the Daydream screen, then select the wrench next to it.
2. Choose specific albums or groups of photos to cycle through next time you launch Daydream.
3. Touch the Back button, then launch Daydream.
You’ll see the selected images appear as a screensaver on your display.
Your options for what appears on your screen will expand over time. As you install new apps that integrate with Daydream, they’ll be added to a list of apps that you can select within Settings to appear when you've turned on Daydream.
