Today, the Alexa Voice Service (AVS) is introducing an AVS Hosted Splash screen to create a better and more consistent Alexa registration experience for devices with Alexa built-in. We are introducing the AVS Hosted Splash screen for two reasons: to eliminate the time device makers spend engineering their own webview to host an Alexa splash screen and to help improve customer engagement with Alexa built-in products. Amazon will continuously monitor and regularly improve the AVS Hosted Splash screen, which currently features three content zones optimized for registrations: graphic, copy, and call-to-action. This will also ensure consistency of the Alexa registration experience across all devices.
How to Enable the AVS Hosted Splash Screen
You will need to request the new alexa:voice_service:preauth scope and the alexa:all scope when requesting Login with Amazon (LWA) to register a new customer (and remove your existing splash screen if applicable). The AVS Hosted Splash screen will then be deployed automatically to the device that creates a LWA request in the companion app. See our documentation for more details.
If you already have a product in market, you can choose to either keep your existing splash screen or update to the AVS Hosted Splash screen. If you are developing a new product, you must use the AVS Hosted Splash screen and you no longer need to build and host your own Alexa splash screen.
