 ### Update: Google has revealed the "advanced flow" — it is not a solution
 
-On March 19, 2026, Google [published details](https://android-developers.googleblog.com/2026/03/android-developer-verification.html) of the "advanced flow" mechanism intended for "power users" to allow installation of applications from unverified developers after the lockdown takes effect. This flow requires enabling [Developer Mode](https://www.android.com/intl/en_uk/articles/enable-android-developer-settings/), self-attesting that you are not being coerced, restarting your device, and waiting a mandatory **24 hours** before being permitted to install applications from unverified sources. Critically, the entire flow is delivered via Google Play Services — not the Android OS — meaning Google can modify, restrict, or remove it at any time without an OS update and without 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.

It goes like this:
+
+1. Enable [Developer Mode](https://www.android.com/intl/en_uk/articles/enable-android-developer-settings/) by tapping the software build number in _About Phone_ **seven times**
+1. In Settings > System, open Developer Options and scroll down to “Allow Unverified Packages.”
+1. Flip the toggle and answer a scare screen confirming that you are not being coerced
+1. Enter our device unlock pin/password
+1. Restart your device
+1. **Wait 24 hours**
+1. Return to the unverified packages menu at the end of the security delay
+1. Scroll past additional scare screen warnings and select either “Allow temporarily” (seven days) or “Allow indefinitely.”
+1. On the next scare screen, confirm that you understand the risks.
+1. You can now install unverified packages on the device by tapping the “Install anyway” option in the package manager.

 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.
