Google Messages to stop working on some devices
An uncertified Android device is one that does not follow Google certification process and does not have Google G suite apps pre-installed on it. For a device to be officially called an Android device, it must go through the certification process ahead of its release.
Till 2018, it was possible to run Google apps even on uncertified Android devices but Google has fixed the loophole now.
An average user will rarely find an uncertified Android device. However, new devices from Huawei could be the possible examples of the devices affected by the latest notice.
