Google slows Android sideloading to trip up scammers

Google describes an advanced flow for sideloading Android apps from unverified developers that targets scam scenarios by requiring deliberate actions (enable developer mode), a check that no one is guiding the process, a restart and reauthentication, a one-day waiting period, and final biometric or PIN confirmation before allowing installation; users may permit temporary access (e.g., seven days) and receive source warnings during installation.
