In an internal Google document introduced by Google’s own attorneys on Wednesday, Android security boss Dave Kleidermacher showed that at one point Android was deemed to be at “-18 percent” on privacy and security compared to iOS.

“The result of their scoring shows iOS has an 18 percent advantage,” he explained.

A passage from the same presentation read:

The Google Play vetting process is less thorough than Apple’s app review so more malicious apps are allowed onto the platform. While Google Play Protect should mitigate this problem, it is not always successful.
