Google Rolls Out Android’s New Sideloading Flow with Delays
Google has begun rolling out its “advanced flow” for Android sideloading, and it comes with a mandated 24 hour delay plus a required device restart. The update is already stirring debate among users who rely on sideloading for apps outside the Play Store.

How the New Verification Process Works

Google deployed its “advanced flow” for installing apps from unverified developers, and it introduces real friction into what used to be a quick toggle. The process now requires a phone restart and a 24 hour waiting period before sideloading is enabled. Notably, ADB installations remain exempt from these new requirements.

The rollout comes from Google’s Android Community Engagement Manager, Mishaal Rahman, who announced it on the r/Android subreddit. This is described as the “first version” of the flow, rolling out gradually, so not every user will see it right away.

Here’s what the actual process looks like for users who want to sideload:

  • Navigate to Developer Options and select “Apps from unverified developers”
  • Authenticate using your screen lock
  • Confirm you are not being pressured to change the setting
  • Restart the device and wait 24 hours
  • Return to the setting and choose to allow unverified apps for either seven days or indefinitely
  • Confirm a final warning at install time, with an “Install anyway” option

The Scam Problem Behind the Friction

Google says the deliberate friction, especially the restart and 24 hour delay, is designed to disrupt a specific type of scam where victims are coached in real time through installing malicious apps. Cutting off that instant install window makes it much harder for scammers to walk someone through the process live.

This advanced flow also applies to updates for apps that are already installed, not just brand new installations. Google confirmed that temporarily disabling the flow grants a 10 minute grace period, allowing users to re-enable it without triggering another full 24 hour wait. The company first detailed these new rules for installing apps from unverified developers back in March.

Android Users Push Back

The changes have landed poorly with a significant chunk of the Android community. A prior poll by Android Authority found that 79% of over 7,300 respondents felt the rules undermine Android’s openness, with some calling the approach outright “overkill.”

Reddit reaction has echoed similar frustration. Commenters specifically questioned why updates to already installed, unregistered apps face the same friction as fresh installs. Rahman addressed this directly, clarifying that an app installed before verification could still receive a malicious update later. He also noted that where an APK comes from is irrelevant. What actually matters is whether the developer behind it is registered.

Rollout Timeline Across Regions

Developer verification enforcement begins September 30 in Brazil, Indonesia, Singapore, and Thailand. Initially, it covers apps distributed through Google Play, HONOR App Market, OPPO App Market, Galaxy Store, Palm Store, V-Appstore, and GetApps.

The rollout includes a new Android Developer Verifier system service, which users can manually install from Google Play. Broader enforcement across all regions and app installation methods is scheduled for 2027.

Hashlytics Take

Google’s stated goal here is legitimate. Real time scam coaching is a genuine attack vector, and friction does disrupt it. But the framing conveniently sidesteps the fact that this also hands Google significantly more control over what counts as a “verified” developer on a platform that has always marketed itself on openness. The scam justification is real, but it is also the easiest possible cover for a broader shift toward gatekeeping that Android has resisted for over a decade. Both things can be true at once, and users are right to watch the 2027 global rollout closely rather than take the security framing at face value.
