There's a ton of work that goes into building an Android smartphone. After designing the hardware, ordering components, and then manufacturing the product, companies then have to work on getting Android up and running as well. Not only that, but if they want their product to be competitive then they need to put the device through Google's compatibility certification tests in order to ship Google's apps on their device. However, this process can take up to 3 months to complete. To allow partners to ship new devices more quickly, Google, in partnership with MediaTek, is announcing a new project called GMS Express that reduces the certification process from 3 months down to potentially 4 weeks.

Since Android is open source, it can be modified and built to run on all sorts of different hardware configurations. However, this can lead to inconsistencies with how Android behaves from one device to another, thus Google sets up certain requirements to make sure that basic APIs and hardware function consistently across all Android devices. To enforce these requirements, Google leverages its suite of Google apps including the Google Play Store (bundled as part of Google Mobile Services) to force companies to abide by their rules. If an Android build on a device doesn't pass Google's certification process, then they aren't allowed to ship their devices with most popular Google apps pre-installed.

As mentioned, this certification process can take up to 3 months to complete and this means time, manpower resources, and money for each smartphone, tablet, and smartwatch that gets put up for sale. For big companies like Samsung, this is likely just a minor annoyance but this can be a huge barrier for some smaller startup companies that want to get into the market.

With GMS Express, Google wants to reduce the certification time down to 4 weeks. SoC manufacturers like MediaTek will provide Android device manufacturers pre-tested, pre-certified, and fully compliant builds of Android. Devices built in this way will still need to go through a final certification process since the code will likely be changed to add in more features. But it will be incredibly convenient for OEMs that are trying to get an Android device to market quickly. Google has announced that dozens of brands have already joined GMS Express.
