Update: Google has revealed the “advanced flow” — it is not a solution
On March 19, 2026, Google published details of the “advanced flow” mechanism intended for “power users” to allow installation of applications from unverified developers after the lockdown takes effect. It goes like this:
Enable Developer Mode by tapping the software build number in About Phoneseven times
In Settings > System, open Developer Options and scroll down to “Allow Unverified Packages.”
Flip the toggle and answer a scare screen confirming that you are not being coerced
Enter our device unlock pin/password
Restart your device
Wait 24 hours
Return to the unverified packages menu at the end of the security delay
Scroll past additional scare screen warnings and select either “Allow temporarily” (seven days) or “Allow indefinitely.”
On the next scare screen, confirm that you understand the risks.
You can now install unverified packages on the device by tapping the “Install anyway” option in the package manager.
This entire flow is delivered through Google Play Services, not the Android OS, meaning Google can modify, restrict, or remove it at any time without an OS update and without any user consent. The advanced flow has still not appeared in any Android beta, dev preview, or canary release. As of the date of this update, it exists only as a blog post and UI mockups. The community is being asked to accept a product announcement as a functional safeguard five months before the mandate takes effect.
Until Google provides a shipping implementation that can be independently verified, our position remains unchanged: all apps from non-registered developers will be blocked once their lockdown goes into effect in September 2026.
