Android tablet owners will still be able to install apps from outside Google Play, but Google is building substantially more friction into that path when an app comes from an unverified developer. In its initial rollout, the company’s developer-verification system can require users to wait 24 hours before allowing those installations through an advanced flow.
The policy is currently being tested on certified Android 7-and-newer phones and tablets in Brazil, Indonesia, Singapore, and Thailand. Google lists a global rollout for 2027 and beyond, but U.S. availability and timing have not been confirmed.
A delay designed to disrupt phone scams
The extra steps target a familiar fraud scenario: a criminal keeps a victim on the phone and directs them to disable safeguards and install an APK supposedly needed to secure a bank account or fix a device. A mandatory pause gives the person time to reconsider the request rather than immediately following instructions under pressure.
To enable installation from an unverified developer under the new advanced flow, a user must complete the following process:
- Turn on Developer Mode.
- Confirm that another person is not directing them to disable Android’s protections.
- Restart the device and sign in again.
- Wait 24 hours.
- Return and confirm the choice with a fingerprint, face authentication, or PIN.
Afterward, the user can allow installs from unverified developers either for seven days or indefinitely. That is a meaningful inconvenience for enthusiasts who deliberately sideload software, but it is also the point of the design: the protection is meant to interrupt urgency-based social-engineering attacks.
What is changing first—and what is not
The first enforcement phase, which began September 30, 2026, applies to installations through participating app stores in the four test countries. Google’s FAQ says installs from other stores and direct sideloading are not yet subject to the new requirements in that initial phase. Those broader restrictions are expected as the program expands globally.
Participating stores include:
- Google Play
- Samsung Galaxy Store
- HONOR App Market
- OPPO App Market
- Xiaomi GetApps
- vivo V-Appstore
- Transsion Palm Store
Android Debug Bridge installation is an important exception for technical users. Google says ADB installs are not subject to the 24-hour waiting period.
Verification is about the developer, not Play Store exclusivity
The system does not require every APK to be distributed through Google Play. Developers can continue offering apps on their own sites, through alternative stores, or through other channels. To retain the normal installation experience on certified Android hardware, however, a developer’s identity and the app’s package name must be registered with Google’s system.
Google says more than 99% of Play Store apps are already registered automatically, so most mainstream tablet and phone users may see little change. The company says its analysis found more than 90 times as much malware in sideloading sources as in Google Play, which is the security rationale behind the policy.
There is a limited-distribution option for students and hobby developers: it can distribute an app to as many as 20 devices without a government ID or the standard registration fee.
For Android’s more technical audience, the shift does not end sideloading; it turns unverified sideloading into a deliberately slower decision. The eventual global rollout will matter most to users who rely on independently distributed tablet utilities, beta software, and niche apps, while the exact U.S. rollout schedule remains unknown.
