On August 28, 2025, Google made an announcement stating that it would implement substantial modifications to the app sideloading feature within the Android system. Commencing in 2026, the company intends to impose restrictions on the installation permissions of third-party apps on certified devices. Under this new arrangement, only apps developed by authenticated developers will be permitted to operate.

This strategic shift is designed to mirror the closed ecosystem model of iOS. By doing so, Google aims to bolster user privacy protection, curtail app access to user data, and mandate that app developers explicitly articulate the purpose of data collection and secure user consent.

To combat the threats posed by malware and financial fraud, Google plans to implement the new policy via updates to the Play Store. In October 2025, early registration will be made available to a select group of developers, with registration opening up to all developers in March 2026.

Starting in September 2026, app blocking will be enforced in Brazil, Indonesia, Singapore, and Thailand. In these regions, apps developed by unauthenticated developers will no longer be installable. The policy will then undergo a phased global rollout beginning in 2027.

While this policy is anticipated to elevate the privacy protection standards of the Android system, it could pose challenges for free apps that rely on advertising revenue. Additionally, it has sparked concerns regarding the potential shift towards a more closed Android ecosystem.
