Why there is a yellow or red line at the bottom of the screen？The bottom light on the screen indicates the status of the Alexa. Red means Alexa is not available now. It might be because of an Alexa server problem, the Mic is muted, or your local network problem. Yellow indicates there are messages or notifications in your Alexa inbox. You can use the Alexa app to read them. And then the yellow indicator will disappear.
