Important - The following is an edited version of an official message from Google about Huawei devices. For more information, please consider viewing the original post by Google (https://support.google.com/android/thread/29434011?hl=en) and search for any other details that may pertain to your region.
As of May 16, 2019, the US government has prohibited all US companies, including Google, from collaborating with Huawei.
This means that Google is prohibited from working with Huawei on new device models or providing Google’s apps including Gmail, Maps, YouTube, the Play Store and others for preload or download on these devices.
US law currently allows Google to work with Huawei on device models available to the public on or before May 16, 2019. Any device made available after this date will likely experience issues playing Sky.
Due to these government restrictions, Google’s apps and services are not available for preload or sideload on new Huawei devices.
Because of the government restrictions described above, new Huawei device models made available to the public after May 16, 2019 have not been able to go through this security process nor will they have Play Protect preloaded. As a result, they are considered “uncertified,” and will not be able to utilize Google’s apps and services.
In addition, sideloaded Google apps will not work reliably because we do not allow these services to run on uncertified devices where security may be compromised. Sideloading Google’s apps also carries a high risk of installing an app that has been altered or tampered with in ways that can compromise user security.
To check if your device is certified, open the Google Play Store app on your Android phone, tap “Menu” and look for “Settings.” You will see if your device is certified under “Play Protect certification.”
