Currently, China’s mobile phones do not have Google services. This can only be done after rooting is successful. Because Google’s business is restricted in China, the services provided by Google are basically unavailable in China. If you want to use Google services, you must install the Google service framework, which is not supported by domestic mobile phones. Google Mobile Service

Google Mobile Service (English: Google Mobile Service) is a service of Google, which is referred to as "GMS". Google embeds Google Mobile Services (GMS) into the Android mobile phone system and grants varying degrees of authorization to Android mobile phone manufacturers. It is designed to allow users to use Google search, Google Maps, Gmail, YouTube and other Google service products using mobile phones or other mobile devices.

Google Mobile Services and Android

Google embeds Google Mobile Services (GMS) into the Android mobile phone system, and grants varying degrees of authorization to Android mobile phone manufacturers to integrate Android The mobile phone manufacturers of the system are divided into three levels:

1. Non-authorized authentication: Free use of Android operating system, but GMS cannot be embedded;

2. Partially authorized authentication: embedded Some GMS services, but the mobile phone cannot be marked with Google's trademark;

3. Fully authorized certification: all GMS services are embedded, and the Google trademark of "with Google?" can also be used;

Currently on the market, only a few mobile phone manufacturers have passed full authorization certification.

Google certification is not as easy as imagined. Google must consider the level of certification based on the strength of the manufacturer and regional factors.

For manufacturers, in addition to gaining more access to Google services, GMS is also an effective means to create brand differentiation.
