Google launched Android 10 last month. And now Just a month after its launch, Google has announced that all Android phones launched after January 31, 2020 must ship with Android 10.

According to Google’s GMS documents accessed by XDA Developers, Google has made it mandatory for all smartphone makers to ship new smartphones approved after January 31, 2020 to ship with the lastest version of the company’s mobile operating system. GMS stands for Google Mobile Services, which is essentially a suite of Google apps, services, and libraries that must be licensed by smartphone makers like Samsung, Xiaomi, Vivo and others. Licensing GMS suite is important because it enables smartphone makers to pre-install Google Play Store and Google Play Services on their smartphones.

The documents also confirmed that Google will not approve any new smartphones running on Android 9.0 Pie after January 31. The new deadline, however, does not ensure that all smartphones launched after January 31, 2020 will run on Android 10. Smartphone makers can launch new phones running on Android 9.0 Pie if they have sought approval for GMS from the Mountain View, California based company before the January 31 deadline. All Android phones approved after January 31, 2020 will run on Android 10.

As far as the smartphones that won’t get Android 10 update are concerned, the report says that Google will continue to approve software updates based on Android 9.0 Pie until the launch of Android 11, which is likely to happen in August 2020. After the launch of Android 11, Google will only approve security updates for devices running on Android Pie.

Apart from making changes pertaining to Android 10 shipment, Google is also making it mandatory for Android smartphone makers to pre-install the Digital Wellbeing app with built-in parental controls on their smartphones. Alternatively, smartphone makers can also include their custom Digital WellBeing and parental control solution on their smartphones. According to a separate report by the publication, Google is requiring all smartphones launched after September 3, 2019 running on Android 9 Pie or Android 10 to come with a wellness app and parental controls.
