A backdoor that enabled Huawei's Mate 30 devices to install Google's Play Store and other apps has been shut down. LZ Play, an app that promised to allow users to run the apps they know and love, has been taken down after a researcher found it harnessed secret Huawei APIs. Subsequently, Google removed the phone from its SafetyNet system, essentially a list of trusted devices that could access Google services.
The two devices that Huawei has released since the ban, the Honor 9X in China and the Mate 30 series, both ship without Google Play. Since the release of the ban, Honor 9X and Mate 30 series released by Huawei, were not allowed to install Google Play.
Using apps to route around the Google ban is not uncommon, with apps like GO Google Installer being used on western phones brought to China. In this case, however, GO Google Installer didn't work for the Mate 30 series.
On its side, Google has also moved to block the Mate 30 from being able to use any number of tricks to access Google Play. The company's SafetyNet system is designed to check if a phone was secure (and had not been rooted or otherwise hacked) enough to run Google's apps. As Android Central's Alex Dobie found, the Mate 30 Pro was certified by SafetyNet last week, but its approval has since been pulled.
