Google GMS certification role and significance

Many foreign operators require suppliers to pass GMS certification. In some places where foreign operators dominate the mobile phone market, it is difficult to take the operator channel without GMS certification. At the same time, at the recent Android conference, Google once cut off the major MADA vendors that did not come to the conference and failed the shipment. At the same time, it is even tougher that in the third quarter of 2017, GMS will be mandatory. Certification, otherwise they will not be used.

Google services are essential Internet services for products such as mobile phones and tablets. Their laws also explicitly require that these products bear the Google Android logo. Google GMS certification is a proof of identity and an effective means of opening up brand differentiation.

2.GTS test
3.Test CTS verifier manually
CTS Verifier is part of the CTS test and needs to be performed manually. It is mainly used to test functions that cannot be tested by automatic test systems, such as cameras and sensors.
