WebView Crash: Finch Configuration Disaster

The text analyzes the Android app stability crisis of March 2021, detailing how a global outage occurred when a configuration bug was deployed via Google’s remote experimentation system, Finch. This faulty setting critically broke the Android System WebView component—a shared library used by applications like Gmail and Outlook to display web content—resulting in immediate and persistent crashes across millions of devices worldwide. Because WebView and Chrome share underlying infrastructure, the fix required users to update both the WebView and Chrome applications to a non-buggy version within hours of the incident. This widespread failure demonstrated the critical risk posed by rapid config changes in core system components, leading Google to institute systemic safety mechanisms, most notably the implementation of a new WebView Safe Mode to automatically detect and revert future problematic experiments.
