This release does not have a Play Store Description, so we grabbed one from version 188.8.131.522:
Huawei Mobile Services brings Huawei users many advanced features like Huawei ID, push notifications, payments and other services (availability varies by region).
A Huawei ID is required to access all services, including Themes, Mobile Cloud, HiCare, Phone Clone, Huawei Wear, Huawei Health and many more (availability varies by region).
Users can register a Huawei ID during the application’s first use. Go to Settings > Huawei ID to manage your account and update personal information.
