Google sets Android sideloading deadline: verification rules go live September 30

Google has finally put dates on its Android sideloading overhaul, confirming that developer verification protections will reach the first users on September 30, 2026. The rollout begins in Brazil, Indonesia, Singapore, and Thailand before a global expansion across certified Android devices in 2027.

For most people, nothing changes overnight. A new system service is quietly arriving on Android phones this month through Google System Updates, but it won’t touch how you install apps just yet. The friction kicks in later, and only if you stray outside the Play Store.
