Google will begin blocking unverified Android app installs on certified devices in Brazil, Indonesia, Singapore, and Thailand from 30 September 2026. Developers who have not completed identity registration with Google will find their apps cannot be installed through normal channels on these devices. This is a significant supply chain and app distribution security measure aimed at reducing malicious or fraudulent apps reaching end users.

Security Architect’s Take: If your organisation distributes internal or customer-facing Android apps in any of these four markets, audit your Google Play developer accounts now to confirm identity verification is complete before the September 2026 deadline — failure to do so will break app delivery for affected users on certified devices.
