Google is rolling out a new system service for Android devices to verify app origins from registered developers, starting this month. Verification requirements will officially begin on September 30, 2026, for users in Brazil, Indonesia, Singapore, and Thailand, covering apps from major app stores like Google Play and Samsung Galaxy Store. Users can still sideload apps, but those from unregistered developers will require additional installation steps. A limited-distribution developer account will be introduced in August for hobbyists and students, allowing app sharing with up to 20 devices without ID or fees. The phased rollout will continue through 2026, with global expansion of verification requirements expected in 2027.
