Unverified Apps Now Face a 24-Hour Wait

Installing unvetted apps on Android will soon require a deliberate exercise in patience.

Google has started rolling out its “advanced flow,” a new verification process that introduces an intentional 24-hour waiting period for users attempting to sideload software from unverified developers. The feature acts as a bridge ahead of Google’s broader enforcement of mandatory developer identity checks on certified Android devices.

The initiative follows Google’s effort to bind app creators to real-world identities, stripping malicious actors of the anonymity often used to spread malware.

“Developer verification links real-world entities with their Android applications, making it much harder for malicious actors to quickly distribute more harmful apps after we take the first one down,” said Mishaal Rahman, Google’s Android community engagement manager, in an announcement on the r/Android subreddit.

To unlock installations from unregistered creators without using the Android Debug Bridge (ADB), users must complete a multistep sequence:

• Access Developer Options by tapping the device build number seven times.
• Toggle the setting for apps from unverified developers and confirm their screen lock.
• Review anti-coercion warnings confirming they are not acting under pressure.
• Reboot the device to sever active calls or remote sessions and initiate a mandatory 24-hour countdown.
• Return after 24 hours to enable the permission for seven days or indefinitely.

The setup is a one-time configuration across a user’s ecosystem, with a 10-minute grace period if it is accidentally disabled. However, if the setting remains off, both new installations and updates for unregistered apps will fail.

Rollout schedule and scope

The system operates via a background service called Android Developer Verifier, distributed through Google Play Services.

Enforcement formally begins on Sept. 30, 2026, across Brazil, Indonesia, Singapore, and Thailand. Initial checks will apply to downloads from Google Play, Galaxy Store, HONOR App Market, OPPO App Market, Xiaomi GetApps, Palm Store, and V-Appstore. Full global enforcement across all certified Android devices is scheduled for 2027.

Apps installed via ADB remain exempt from identity checks and waiting periods.

Why Google is making sideloading harder

Google has framed the extra friction as protection against social-engineering scams in which attackers persuade victims to install malicious Android apps while guiding them through the process in real time. Requiring a reboot and a 24-hour delay could interrupt that kind of attack before an installation is completed.

The trade-off is that legitimate users who deliberately install software from pseudonymous developers, modding communities, or other unverified sources will face the same barriers. Because the verification system is being enforced on certified Android devices through Google’s ecosystem, the change also gives Google a larger role in determining how easily software from outside conventional app stores can reach users.

Android will still allow technically advanced users to install apps through methods such as ADB. But for everyone else, Google is drawing a clearer line: sideloading remains possible, while anonymous software distribution on mainstream Android devices is becoming considerably less convenient.
