Google system services is the API layer that enables unique Google features on Android and is available on every Google-supported device. It provides app developers a unified way to integrate Google services into their apps. For more details, see Learn more about Google system services updates.
The Google system services beta program gives you early access to new versions of Google system services, including Google Play services. This is especially useful for developers, as it allows them the ability to test their apps on their own devices. It also allows Google the opportunity to provide a better experience to users worldwide.
Keep in mind that beta versions of Google system services might be less stable than officially released versions. This means that some apps might crash or features might not work correctly. For example, your device could repeatedly crash, making services unavailable.
