Google genuine app will be unusable on Google unauthenticated Android device

We found out that Google is planning to block Android smartphones that have not received various certifications listed in the terms of use of Android. There is a possibility that all Android applications may not be available on some Chinese-made terminals etc.

Google now blocks GApps on uncertified devices, but lets custom ROM users be whitelisted

Android for mobile terminal OS is open source, not only available for free but also allowed to create improved custom OS. In contrast, various Google service applications are not open source, but they are required to be used in accordance with Google's guidelines. For example, in order to use applications such as "Google Maps", "Gmail", "Google Play Store" released by Google, the device manufacturer develops a terminal according to the document "CDD" defining compatibility created by Google It is also required to pass the compatibility test "CTS". As long as you comply with these standards, the stable operation of Google services is guaranteed, so you can use various Google Android applications available on the Play Store or on the Play Store.

In the first place, since "Android" is a trademark of Google, terminals that do not comply with the compatibility requirements stipulated by Google are not permitted to name Android, and are strictly called "Android fork". For example, Xiaomi's MIUI and Amazon's Fire OS are famous as Android folks. Although the base of the OS is Android, these Android fork terminals offer their own applications, and users are basically assumed to be used within that ecosystem.

Nonetheless, since the base is Android, many Android applications will work on Android fork terminals as is, so users can even install the Google Play Store application that manually provides Google Maps, Gmail, Android applications. Originally it is a Google service application pre-installed on Android terminal, but APK file is released on bulletin board, custom ROM site, third party app store, etc, Android fork terminal user does not obtain Google's certification There is the fact that you are using the Google service application in a form.

If the terminal is not authenticated, "Uncertified" (not authenticated) is displayed in "terminal authentication" in "Settings" of the Play Store.


Google was in a state of tacit knowledge for terminals that have not been authenticated before, but there is a possibility that we have steered the direction of not allowing the use of the Google service application of unauthenticated terminal to the forum on custom ROM etcXDAHas been pointed out.

liam_davenport reports that a screen called "Device is not certified by Google" (terminal not certified by Google) appears on an unauthenticated terminal. When this screen is displayed, the sign-in of the Google account will be canceled and you will not be able to use the Google service application. Of course you will not be able to get Android app from Google Play Store. The choice given to users is "to send a mail to certify the terminal manufacturer". Manufacturers who have received complaints will effectively not accept the terminal in the market unless they receive CTS certification according to the terms of Google.


In addition, Google is liberal for custom ROM, in the case of custom ROM users, they can notify the Android ID from the registration page of the following terminal and add it to the whitelist, and can cancel the lock. However, in order to find out the Android ID of my terminal, it is necessary to input "settings get secure android_id" with the ADB command, and it is not known at all for the XDA forum participants, and it is said that hurdles are high for many light users I can not get it.
