GMS stands for Google Mobile Services, which is a collection of proprietary applications and APIs developed by Google for manufacturers of Android devices such as smartphones, tablets, and smart TVs. GMS is not part of the Android Open Source Project (AOSP), which means that an Android manufacturer needs to obtain a license from Google to legally pre-install GMS on an Android device. The GMS bundle includes popular Google applications such as Google Search, Google Chrome, YouTube, Google Play, Google Drive, Gmail, Google Maps, Google Photos, Google TV, and YouTube Music. GMS provides end-users with secure and consistent functionality across devices. Manufacturers have the option of pre-installing specific GMS applications, like Gmail or YouTube, on a device home page or offering them for download through an app store. GMS may vary based on regional availability and licensing requirements. Obtaining GMS certifications creates an agreement between the manufacturer and Google, and GMS devices are pre-loaded with Play Store apps, and they’re subject to Google’s policies for privacy, including the GMS agreements for privacy, data collection, and device updates.
