Google has introduced a yellow warning banner in the Google Play Store to alert Android users about apps that are frequently uninstalled. This banner indicates that an app may not be meeting user expectations and could be due to poor functionality, excessive advertisements, or inflated costs. Additionally, Google has implemented two other notifications: one indicating lower user engagement with an app and another showing fewer users compared to other apps. These features aim to help users make more informed app choices and avoid potentially harmful applications. Google Play Protect is also available to scan downloaded apps for security, including those from outside the Play Store. Users can enable settings to improve harmful app detection, enhancing overall safety in the app ecosystem.
