Android developer verification: what changes and who it affects
From Sept 30, 2026, Brazil, Indonesia, Singapore and Thailand block apps from unverified developers; global in 2027. The 24-hour advanced flow explained.
Google now requires Android apps to be registered to a developer with a verified identity. From September 30, 2026, certified Android devices in Brazil, Indonesia, Singapore and Thailand block the normal installation of apps whose developer hasn't registered. Google has announced a global rollout in 2027. Here's what that means in practice.
Quick summary
| If you… | What changes |
|---|---|
| Only install apps from Play Store | Practically nothing. Google automatically registers the vast majority of Play apps. |
| Install the Play Store APK or other Google apps | Nothing: they're signed and registered by Google. |
| Live in the US, UK, India or any other country outside the four | Nothing in 2026. Expected in 2027. |
| Are in one of the four countries and sideload APKs from unregistered developers | They won't install the normal way. You need the advanced flow or ADB. |
Participating stores
In this first phase, the check applies to apps distributed through seven stores: Google Play, Galaxy Store (Samsung), GetApps (Xiaomi), HONOR App Market, OPPO App Market, V-Appstore (vivo) and Palm Store (Transsion). It covers certified devices on Android 7 or later.
How it works on the phone
Google is shipping a system service called Android Developer Verifier. Before an app installs, it checks whether the app is registered to a verified developer. If it is, the install goes ahead and you notice nothing.
The "advanced flow" for unverified apps
Installing apps from unverified developers remains possible, but Google deliberately made it slow to defeat scams where someone talks the victim into installing a malicious app over the phone:
- Enable developer options on the phone.
- Turn on the option to allow apps from unverified developers, then restart.
- Wait 24 hours. This wait happens only once.
- Re-authenticate (fingerprint, PIN or pattern) and you can install.
The advanced flow began rolling out gradually in August 2026, so it may not appear on your phone yet. Installs over ADB from a computer are unchanged.
What it means for APK users
- Well-known apps: most serious developers have already registered, including those distributing outside Play.
- Modded apps: can't carry the original developer's registration and won't install the normal way in affected countries. That's largely the point.
- Open-source and hobby projects: Google created limited-distribution accounts, with no fee and no ID, for sharing apps with up to 20 devices.
What hasn't changed
Play Store and its manual install aren't affected: Google is a verified developer. How to tell an APK is genuine hasn't changed either: the signature remains the proof, as explained in the verification guide.
