Google blocks access to its apps on uncertified Android devices
Android is an open source operating system and a million other varieties have blossomed. If your Android device is certified by Google, you`re allowed to distribute Google`s official Android apps on it. Google is now checking the build date of your Android system image when you attempt to run Google apps. If you have an uncertified device and you`re running a version of the Android OS that was compiled after March 16, 2018, Google apps won`t work.

Google app users won`t be prevented entirely from loading ROMs but they will have to register their device IDs on a whitelist every time they undergo a factory reset. Image source: Reuters
