Does Alexa update automatically?
Alexa devices receive software updates automatically over Wi-Fi. Depending on the Wi-Fi connection, it can take up to 15 minutes to install the software update.
How do I check for Alexa updates?
You can check which version your Echo is running by opening the Alexa app on your phone (or by going to alexa.amazon.com in your web browser). If you have an Echo Show, you can swipe down from the top of the screen, tap Settings then Device Options and Check for Software Updates.
