Quick answer

Google has begun rolling out a new app installation process on Android for unverified developers, which includes a device reboot and a 24-hour waiting period.

Google has begun the phased rollout of an updated app installation process on Android from unverified sources. The new mechanism, called "Advanced Flow," requires users to complete several steps, including enabling Developer Mode, authenticating via screen lock, and waiting for 24 hours after rebooting the device. Only after this can APK files from developers not verified by Google be installed.

The changes are aimed at combating fraud, particularly cases where victims are tricked into installing malicious apps. However, the process has drawn criticism from users and experts who consider it overly complex. For example, updates to already installed apps from unverified developers will also be blocked unless the "Advanced Flow" is activated.

The first countries where the new rules will take effect on September 30 are Brazil, Indonesia, Singapore, and Thailand. Initially, the restrictions will apply to apps distributed via Google Play, as well as stores like HONOR, OPPO, Samsung Galaxy Store, and others. By 2027, the changes are planned to be expanded to all regions and all app installation methods.

It is worth noting that users who utilize ADB (Android Debug Bridge) will be able to bypass the new restrictions. Google has also confirmed that temporarily disabling the "Advanced Flow" grants a 10-minute grace period to re-enable it without needing to wait another 24 hours.
