Google says that now, each new Android-certified system goes by the identical app scanning course of as apps on Google Play, and that its safety scanner appears to be like for different frequent safety and privateness points and denies system certification till system producers repair these issues. And in 2018, it elevated its payouts to safety researchers, surpassing $three million in complete payouts.
