The Google Play Store is introducing a new filter that allows users to "filter apps that link to external apps." This feature, revealed through an APK teardown, suggests a shift in strategy focusing on app behavior rather than content. The purpose of the filter is unclear, raising questions about its implications for security and app interactions. The optional nature of the filter prompts speculation about whether it is a security measure and what "external" links encompass. The tech community is awaiting further clarification from Google regarding this development and its potential impact on user experience and app visibility.
