The Huawei P 30 Pro, unlike its successors, was (mostly) free from controversy and ran Google Play services without any issues. However, several P30 users are now reporting that their devices are failing Google’s SafetyNet check out of the blue. The issue appears to be random and is affecting devices that run Android Pie-based EMUI 9 and Android 10-based EMUI 10 (which is currently in beta.) It is usual for devices running beta software to fail the checks as they’re not certified by Google as safe. If a device fails the SafetyNet check, it will be unable to use services such as Google Pay, banking apps, and even Pokemon Go. In a statement to Android Authority, Huawei had the following to say:

Usually for the sake of beta testing, Google allows vendors’ beta OS version on specific models to appear and behave as certified version/device even if this version/device combination is still in the process of being certified.
