Google MADA/GMS certification

Google MADA Certification, also known as the Mobile Application Distribution Agreement, is a mobile application release protocol. Currently, there are many devices that have obtained Google MADA certification, and many manufacturers have this requirement. It is suitable for devices that use Android systems and wish to pre install various software from Google. The devices that apply for MADA certification must meet Google‘s CDD requirements, and the iterative Android version is updated every year, At present, the devices that apply for MADA certification are mainly mobile tablets.

Google GMS certification, AER certification, why do GMS certification?

1. What is GMS certification?

The Android system is an open source system. To legally use the Android operating system and use the Google Play store, CTS or GMS certification is required. If Google completely stops cooperating with Huawei, Huawei‘s future new mobile phones will not only not be able to obtain GMS certification, but may not even be able to obtain CTS certification and VTS (Vendor Test Suit).

A. CTS certification: Google Play store can be used

CTS (Compatibility Test Suite, Compatibility Test Suite) is a framework API test on the Google Android instrumentation interface to ensure that the software and hardware of the Android device can comply with the Google Play compatibility specification, ensuring that users download in Google Play The program can be executed correctly on the device.

Since Google does not provide Google Play applications in the source code, manufacturers‘ devices must pass the CTS test before they can apply to Google to use Google Play. CTS test is a free service, manufacturers can go to the official website to download and test by themselves. After the final test, if the results meet the specifications and are passed to Google, the authorization to use Google Play (Android Market) can be obtained.

In other words, devices without CTS certification will not be able to use Google Play applications.

B.GMS (Google Mobile Service, Google trademark and legal built-in cloud service):

GMS (Google Mobile services) certification, mainly for the verification of Google API. After certification, the Google trademark can be printed on the device, and the authorization to use Google cloud services includes Gmail, Google Maps, Youtube, Google Play Store, Calendar, etc. program. Since these programs cannot be simulated and tested in advance, they must be authorized and certified by Google and paid to Google. Therefore, due to timeliness and cost considerations, non-international manufacturers usually do not have GMS certification.

Furthermore, if it is not a big factory, Google will not spend time to help small factories do GMS certification. If Huawei’s future new mobile phones do not have CTS/GMS certification, can consumers use Gmail and Youtube? Since Gmail, Youtube..Google services can be opened through the webpage, they can still use these services without Google certification, but there are more A procedure is a little more troublesome. In other words, the main difference between CTS and GMS certification is whether the mobile phone is preloaded with Google authorized services (GMS certified mobile phones are preloaded).

The benefits of GMS certification, in addition to the pre-loaded Google authorized services, are mainly that the mobile phone has passed Google‘s double certification in the compatibility test, the product quality meets the regulations, and the use of Google‘s APP services is relatively guaranteed.

Without GMS certification, you cannot use GOOGLE or Android icons for publicity, and you cannot legally use Google mobile services. Furthermore, the CTS certification of some third-tier brand mobile phones (especially counterfeit mobile phones) may be fake. If you download more complex 3D games or specific APPs, they often cannot be used due to compatibility problems. Furthermore, for some counterfeit mobile phones, if the original factory settings are restored, sometimes Google Play will disappear and cannot be returned, and it must be returned to the original factory for reprocessing.

2. Why do Taiwanese telecom operators refuse to sell mobile phones without GSM certification? The main business of telecom operators is to sell phone numbers and telecom services. Do not sell. What troubles will there be for telecom operators without GMS certified mobile phones?

A. No GMS certified mobile phone, no built-in inconvenient and a warning will pop up:

Without GMS certified mobile phones, Google related services cannot be built into the mobile phone, and consumers have to download additional services by themselves, which will only increase the trouble. If there is a problem in use, it is impossible to know the source of the problem, which will only increase the after-sales troubles for telecom operators to sell mobile phones.

Furthermore, according to the manufacturer’s disclosure, if there is no GMS-certified mobile phone, the Android system will automatically pop up a “system vulnerability in the mobile phone” warning. When consumers use mobile phones, information security warnings often pop up automatically, which is annoying to read, which will greatly reduce the user‘s willingness to buy.

B. Third-party APP compatibility issues:

Many third-party apps on Android are based on the GMS specification and require GMS to operate, otherwise they cannot be pushed to the client.

Without GMS certification, in addition to the app that is currently available in China, the third-party apps in non-Chinese regions are likely to have compatibility issues. If there is a compatibility problem with the APP, consumers will usually think that it is a problem with the mobile phone, which will only increase the maintenance logistics burden of the telecom operators.

C. Information security concerns:

Originally, the outside world had doubts about the information security of Chinese manufacturers (the data was sent back to China). Without Google GMS certification, there is one less guarantee. If Huawei uses a self-developed operating system compatible with the Android system, the outside world will definitely be more worried about its information security. Based on user information security considerations, telecom operators are safer not to sell in order not to be suspected of being an accomplice.

D. Infringement disputes:

If Huawei uses a self-developed operating system compatible with the Android system, whether it infringes Google‘s patents or whether it can legally use Google services is controversial. Furthermore, not only the operating system may be suspected of infringement, but whether the mobile phone hardware infringes the patents of other US companies is still uncertain. In order to avoid being a guinea pig for stepping on thunder and being sued for infringement by Google or other US companies, telecom operators must wait and see first.
