Android custom ROM; Users of Android devices running applications from the Google Play Store on devices that are not certified by Google will begin to notice messages such as: "The device is not certified by Google."
We are talking about the Google Apps that usually exist on most Android devices. With the new Google modification, installing these apps is still feasible but does not work properly on affected devices.
A Publication in the XDA Developers forum reports that the change was made on 16 March and that any build developed after that date is affected.
The change affects users running an Android custom ROM and any device has not passed the Google certification process.
Of course, all users of such devices can enroll them manually to obtain the certification. At this time, this process seems to be the only option for Custom ROMS users.
Some users still report that their uncertified device is not yet affected by the limitation.
Manually record a device with custom Android
The first thing you need to do is find your device's Android ID. You should be aware that the Android ID can be changed by installing each new ROM or making some other changes to your device.
Use an application like Aida64 to find the Android ID. If you can not download the app from Google Play, try installing it from a third-party store or from APK Mirror.
Once you find the ID, open the dedicated Google page to manually register your device.
You need to sign in to a Google Account to complete the process. The system limits subscriptions to 100 devices per user.
Finally, we should mention the obvious: Google wants certified devices for more control.
