Instead of Google Mobile Services, EMUI devices have used Huawei Mobile Services, such as the Huawei AppGallery, since 2020 due to United States sanctions imposed during the trade war against China. From Version 13 (2022), Huawei additionally bundled the HarmonyOS TEE microkernel with the Android system; this microkernel for example handled identity security features such as the fingerprint authentication.
