Google Restricts Installing Apps From Outside the Store: Will Your Company's Android App Still Install in 2027?

What changed for installing apps from outside the store on Android?

Since September 30, 2026, certified Android phones in Brazil, Indonesia, Singapore and Thailand refuse to install any app from seven stores, including Google Play and the Samsung store, unless its developer has registered their identity with Google. Google will extend the requirement worldwide in 2027 to every app on certified devices, including apps installed through a direct download link. For your company in Saudi Arabia: if you distribute an app to your employees or customers through a direct link, or you have not confirmed that your store app is registered, the user's phone may refuse to install it after the deadline. Registering outside the store costs a one-time 25 dollars (about 94 riyals), but it requires the app's digital signing key, and that key may sit with the developer who built the app rather than with you.

What started on September 30, 2026?

According to Google's official announcement on the Android Developers Blog, developer identity verification started in only four countries, and only on certified devices running Android 7 or later. The seven stores taking part in this phase are:

• Google Play, from Google.
• Galaxy Store, from Samsung.
• GetApps, from Xiaomi.
• OPPO App Market, from OPPO.
• V-Appstore, from vivo.
• HONOR App Market, from HONOR.
• Palm Store, from Transsion.

Google justifies the move by saying scammers hide behind anonymous names to spread harmful apps that impersonate well-known companies. In its first announcement in August 2025, it said its analysis found over fifty times more malware in apps sideloaded from the internet than in Google Play. Since registration opened in March 2026, developers have registered millions of apps, according to the company.

When does the requirement reach Saudi Arabia?

Google has not named a specific month; all it has announced is that the global expansion begins in 2027. Until then nothing changes for users in Saudi Arabia: Google says on its official FAQ page that an app installed directly or from a non-participating store is not yet subject to the new requirement, but it recommends that developers complete verification before the global rollout begins.

Which of your company's apps will be affected?

• Your app on Google Play: Google says more than 99% of store apps were registered automatically, and that apps using Play's app signing service have their ownership proven automatically. But it asked developers to register any remaining apps before September 30, 2026 to avoid the app being removed from Google Play in every country. Open the home page of your developer account (Play Console) and check the status today.
• An app you distribute through a direct link: such as an app for sales reps, drivers or field technicians, or an app whose link you send to customers on WhatsApp. This is the most affected case, and it needs registration in the Android Developer Console before 2027.
• An internal app on company-managed devices: apps distributed from your organization's private store to centrally managed devices do not need verification, because your IT administrator has vetted them. Google still recommends registering them so they install smoothly if someone downloads them onto an unmanaged device.
• Test builds on developers' machines: installing through the ADB developer tool does not change.
• A trial on a small number of devices: the free limited account lets you share an app with up to 20 devices whose owners approve it, with no government ID and no fee, according to the limited distribution page. But Google designed it for students and hobbyists, so do not build an operational company app on it.

The signing key: the requirement that could stop your app

Every Android app is digitally signed with a private key before release, and that key is how you prove to Google that you own the app when you register it. Google says plainly on its FAQ page: if you lose your signing key, you will not be able to register your app. And if the package name, the app's unique identifier such as com.company.app, is already in use, your key may not be accepted, the request needs an extra review, and you may have to use a new package name. In practice a new package name means a new app: every user has to delete the old one and install it again.

This is the common problem in companies: a freelance developer or a former agency built the app, and the key stayed on their machine. Ask for the key and its password today, and store them somewhere secure that the company owns. If your contract does not require handing them over, read our article on who owns software rights under the copyright law.

What happens to someone who tries to install an unregistered app?

Google has not closed the door completely. According to its explanation of the advanced flow, an experienced user can install an app from an unverified developer after a deliberately long set of steps: turn on developer mode in settings, confirm that nobody is coaching them over the phone, restart the phone, wait 24 hours once, then confirm with a fingerprint or the device PIN. After that they choose to enable it for 7 days or indefinitely, and a warning still appears whenever they install an unverified app.

These steps are designed to defeat scammers who stay on the phone with a victim and coach them into switching off protections. So do not ask your customers or employees to go through them: it means waiting a full day, a warning that casts doubt on your app, and training people to ignore security warnings.

What should you do now?

1. Take stock of your apps: list every Android app your company distributes and how it is distributed: the store, a direct link, or managed devices.
2. Review your Google Play account: make sure all your apps are registered and that the account is in the company's name, not an employee's.
3. Register apps distributed through a direct link: open an Android Developer Console account in the company's name. The full distribution account fee is 25 dollars, and registering as an organization requires a 9-digit D-U-N-S number, which you can get free from Dun & Bradstreet; it is the same number the Google Play account requirements ask of organization accounts.
4. Collect the signing key: from the developer or agency that built the app, with its password, before you need it.
5. Move internal apps to managed devices if they run on the company's own devices, or register them like any other app.

And if you plan to publish your app in the store instead of using a direct link, read the eight reasons apps get rejected in store review first.

What we recommend for every Android app

At Origami we recommend three things with the first release of any Android app: open the developer account in the organization's name, hand the signing key to the client together with the code at project handover, and register the package name with Google from the start. These steps take a few hours at the beginning of a project, and they can save you weeks of republishing if you leave them until 2027. If you have an existing app and you do not know where its key is or whose name its account is in, start with that question before any new development.
