Google’s new Android sideloading rules are arriving early for power users

Google is taking the first step toward fundamentally changing how sideloading works on Android. It has begun rolling out its advanced flow, giving power users a way to sideload apps from unverified developers on certified devices without using ADB.

In March this year, Google started requiring developers to verify themselves. This verification system ties all apps on certified Android devices, including those sideloaded and from third-party app stores, to a verified developer ID. The idea is that this accountability will ensure that malicious actors can't easily distribute malware-infected apps.

Since not all developers will want to verify their identities, Google announced an advanced sideloading flow as well. To use it, users must first enable a toggle in the hidden Developer options menu. They must then authenticate themselves, restart their device, and wait 24 hours before sideloading apps from unverified developers.

Even after all these steps, every time you install or update an app from an unverified developer, Android will display a warning. However, you can bypass it by tapping the Install anyway button.

The process is intentionally complicated, as Google doesn’t want regular users to be fooled by scammers into installing malicious apps on their devices.

Thankfully, if you are a power user, Google will only require you to enable the advanced sideloading flow once. It will automatically remember your choice across all your devices. And if you don't enable the advanced flow, you can still sideload apps from unverified developers using ADB.

Don’t expect the new sideloading flow right away

Google is rolling out the advanced flow gradually, so it may not appear on your phone immediately. A new "Android Developer Verifier" system service must be installed in the background for the feature to work. You can install it manually from the Play Store to increase your chances of gaining access to the new sideloading flow sooner.

In its post on Reddit, Mishaal Rahman, Android's Community Engagement Manager, noted that Google will initially verify app installations from the following app stores beginning September 30, 2026:

• Google Play
• Honor App Market
• Oppo App Market
• Galaxy Store
• Palm Store
• V-Appstore
• GetApps

This year, Google will only enforce the app verification system for Android users in Brazil, Indonesia, Singapore, and Thailand. The system will expand globally to all certified Android devices in 2027.

Google is rolling out the advanced sideloading flow early so that advanced users can enable it ahead of "general availability."
