Samsung Galaxy S4: How to Enable and Use Daydream Feature in Android 4.4.2 Kitkat

Daydream is a feature available in the Samsung Galaxy SIV. This feature will allow you to set the phone to activate an interactive screen saver (photos, real-time info, animation, etc) automatically when the phone is docked or charging. You can use this feature to make the screen becomes more attractive if you're bored with the black screen when your phone is docked or charging.

How to enable and use daydream mode?
Since this feature is not enabled by default, then you have to enable it first before using this feature in your phone. You can do so by using the following steps:

1. Go to Settings.
2. Tap My Device tab.
3. Tap Display.
4. Scroll down to find Daydream and then tap it.
5. Slide the ON/OFF switch to the right to enable daydream. The switch turns green when it's enabled.
6. Select the desired daydream from the following options:
• Colors: select this option to display the colors change effect as the screensaver.
• Desert case: select this option to display the Android 4.4.2 Kitkat Easter egg animation as the screensaver. FYI, this option only available if the hidden Android 4.4.2 Kitkat Easter egg animation has been revealed.
• Flipboard: select this option to display your personalized magazine as the screensaver. You can set how the news will be updated by tapping next to Flipboard and then tap Download new items automatically and then select from the following options: Only On WiFi, Always or Never.
• Google Photos: select this option to display a slide show of the photos on the devices or in the selected Google account as the screensaver. You can select which photos are displayed by tapping next to Google Photos and then select the required Google account and the required albums.
• Photo frame: select this option to display a slide show of the photos on the device as the screensaver. You can select which photos are displayed by tapping next to Photo frame and then select the required albums.
• Photo table: select this option to display the photos scattering effect as the screensaver. You can select which photos are displayed by tapping and then select the required albums.
7. To see the preview of the selected daydream, you can tap Start now button.
8. If necessary, you can also set the time when the daydream mode should be activated by tapping Select dream time button and then select from the following options:
• While docked
• While charging (either AC or USB charging)
• Both (while docked and charging).
9. Done. Now whenever your phone is connected to a desktop dock or charging(depending on the option you have selected in the step #8), the phone will keep the screen on and display the selected daydream as the screensaver.

As a note, since the daydream feature can't work along with the desk home screen, thus when you enable daydream, the desk home screen option will be disabled automatically.
