Google Mobile Services (GMS)

Google Mobile Services (GMS) is a collection of Google apps and APIs including the Play Store, Gmail, Maps, Google Play Protect, and Google Play Services that are pre-installed on certified Android devices. GMS certification is required for full Android Enterprise functionality and app distribution.

GMS Components

GMS includes Google Play Services (core APIs used by many apps), Play Store (app distribution platform), Gmail (email app), Google Maps, Google Assistant, and Google Play Protect (anti-malware service). These services are deeply integrated into Android and essential for many enterprise features.

GMS Certification

Device manufacturers must meet Google’s compatibility requirements to include GMS on their devices. This ensures devices can access the Play Store and use Android Enterprise features. Non-certified devices (like AOSP devices) cannot access GMS by default.

Android Enterprise Dependency

Android Enterprise relies heavily on GMS for features like managed Google Play, push notifications, and device management APIs. Devices without GMS have severely limited Android Enterprise functionality.

Play Store Access

GMS includes Play Store access, which allows device users to download and install apps. Organizations use Managed Google Play (a curated version of the Play Store) to control which apps are available to managed devices.

Push Notifications

Google Cloud Messaging (part of GMS) enables push notifications for MDM policy updates and commands. Without GMS, MDM devices must rely on periodic polling for updates, which is less efficient.

Security Features

Google Play Protect (part of GMS) continuously scans installed apps for malware and suspicious behavior. GMS services also provide regular security patches and updates to protect devices.

Privacy Considerations

Organizations using GMS devices should be aware that Google collects some device and usage data. Organizations can configure what data is collected through Android Enterprise settings.
