It seems like Google is working on a new feature that will warn users about potentially low-quality apps in the Play Store.
Researchers at Android Authority discovered a tool in the Play Store code version 43.7.19-31.
Warnings are likely to be displayed directly on the app’s information page in the Play Store, rather than appearing before downloading. Theoretically, this conservative approach makes sense, as the above criteria do not necessarily indicate that the app is of low quality (especially the last two).
Moreover, some high-quality apps are downloaded for a specific one-time purpose and may be deleted later.
