For a limited time period, from September 23rd to October 1st, 2019, there was a backdoor that allowed for the installation of Google Mobile Services. The backdoor was provided by an application called LZPlay, however, after October 1st, the website that hosted LZPlay's APK installtion file was taken down, and the app began to behave differently, thus no longer allowing the backdoor to be exploited.[14][15][16]
