Our application is a simple native app whose only responsibility is to launch a WebView and display web content. There are no complex UI layers, animations, frequent state updates, or background refresh mechanisms involved.
After recent Fire OS updates, users running our app on Fire TV devices and Fire TV Stick models are experiencing continuous WebView flickering.
The flickering:
Is not a full page refresh
Is not triggered by recomposition, activity recreation, or explicit reloads
Occurs intermittently, with the interval not fixed, but most commonly happening within every ~2 minutes
Continues indefinitely once it starts
This behavior makes the application unusable.
Troubleshooting & Isolation Performed
To rule out application-specific causes, we performed extensive isolation testing:
Built a brand-new minimal application with only a single WebView.
Loaded multiple external websites, unrelated to our app or backend.
Tested on multiple Fire TV and Fire TV Stick devices.
In all cases, the WebView continued to flicker at irregular intervals (typically under 2 minutes), even on well-known external websites. This strongly indicates that the issue is related to the Fire OS WebView or rendering behavior introduced in recent OS updates, rather than our application implementation.
