Google has confirmed it has blocked more than 2.3 million apps as it publishes a new Android and Google Play security update—what you need to know.

Android maker Google just shared that it blocked over 2.3 million Android app submissions at the Play Store last year. The reason was cited as being a violation of a host of its policies which made it very risky for people to use.

Google’s malware scanning Play Protect service will now automatically turn off an Android app’s permissions if it’s potentially harmful. The feature is designed to prevent malicious apps from having access to your phone’s storage, photos, camera, and more.
