For most of Android's history, installing an APK from outside Google Play took two taps: allow "unknown sources," then install. That's changing. Google's developer verification rules took effect on September 30, 2026 in Brazil, Indonesia, Singapore, and Thailand. Apps from developers who haven't verified their identity with Google now go through a deliberately slower "advanced" install flow, which includes a one-time 24-hour waiting period. If you install VPN APKs, which many people do in places where app stores are restricted, here's what's different and how to stay safe.

What Changed and When
- March 30, 2026: Developer verification opened to developers.
- April 2026: A system component called Android Developer Verifier began showing up on devices.
- August 2026: Google began gradually rolling out the "advanced" sideloading flow.
- September 30, 2026: Enforcement started on certified Android devices in Brazil, Indonesia, Singapore, and Thailand.
- 2027: Google plans to expand enforcement globally.
If you're outside those four countries, nothing changes for you yet. But the rollout is coming, and it's worth understanding the new flow before you run into it.
The Advanced Sideloading Flow, Step by Step
To install an app from a developer who isn't verified, you now have to:
- Turn on Developer options (tap Build number seven times in Settings › About phone).
- In Developer options, enable "Allow apps from unverified developers."
- Read and acknowledge the warnings Android shows.
- Wait out a one-time, 24-hour waiting period.
- Go back to the same setting to finish, and choose whether to allow unverified apps for 7 days or indefinitely.
After that, you can turn Developer options off again. The wait is deliberate. Scammers usually work in real time ("install this app now so I can fix your bank account"), and a mandatory day's delay breaks that kind of pressured, on-the-phone attack.
Why Google Is Doing This
The change is aimed at malware like ToxicPanda 2.0, a banking trojan documented in August 2026 that spreads through sideloaded APKs and abuses Android's VPN permission to silence Google Play Protect. Requiring a real, verified identity behind every app makes it harder for a malware author to throw away one developer account and immediately start another. Critics, including many open-source developers, argue it weakens Android's openness and gives Google too much control over what people can install. Both points are fair, and the debate isn't over.
What It Means for VPN APKs
VPN apps get sideloaded far more than most apps, because they're often needed in exactly the places where app stores are restricted or a specific app has been removed. Under the new rules:
- VPN APKs from verified developers install normally, even from outside Play.
- VPN APKs from unverified developers need the advanced flow and the 24-hour wait in enforcing countries.
- Plan ahead if you travel or live somewhere restrictive. Install and set up your VPN before you need it, not during a shutdown or crackdown when a day's wait could matter.
A note on fake VPNs: because VPN APKs are so widely sideloaded, they're also a favourite disguise for malware. A "VPN" APK from a Telegram channel or a random download site is high-risk whatever the new rules say.
What's Not Affected
- Apps from Google Play, including CarrotVPN, install exactly as before.
- ADB installs from a computer are not affected by the advanced flow.
- Non-certified devices, such as custom ROMs without Google services, are outside the scope.
Safe Sideloading Habits
- Download only from the developer's official website, and type the address yourself instead of following a link.
- Be suspicious of urgency. If someone on the phone is pushing you to install something right now, that's the scam the 24-hour wait was built to stop.
- Check permissions after install. A VPN needs the VPN permission and network access. It doesn't need Accessibility, SMS, or Device Admin.
- Turn unverified installs back off (choose the 7-day option) once you're done.
- Keep Play Protect on, and pay attention if it flags an app.
Frequently Asked Questions
Does the 24-hour wait apply to every APK?
No. It applies only to apps from developers who haven’t verified with Google, on certified devices in countries where enforcement is active. Verified developers’ APKs install normally.
Which countries enforce developer verification now?
Brazil, Indonesia, Singapore and Thailand from September 30, 2026. Google plans to expand globally in 2027.
Does this affect apps installed from Google Play?
No. Play Store installs, including CarrotVPN, work exactly as before.
Can I still install apps with ADB?
Yes. ADB installs from a computer are not affected by the advanced sideloading flow.
