When you click the system screensaver options on Android TVs, a screen saver settings menu will open and you can easily choose the Aerial Dream as your default screensaver then set other things such as screensaver timeout and much more.
However, on Amazon devices, when you click on Screensaver settings, it won’t do anything. So, on Amazon devices, you’ll need to use the new toolbox. To do this simply press the home key and open up the Screensaver Manager app.
When you open the application for the first time, it starts by checking your current active screensaver. It will obviously tell you that your default screensaver is the stock screensaver that came with your device if you hadn’t changed anything before.
The Screensaver Manager gives you two options to either Enable Aerial Dream or Disable Aerial Dream. Obviously, you’ll need to click on Enable Aerial Dream and you’ll immediately get a message telling you that Aerial Dream is now your default screensaver.
