Google closes the certification of new models of smartphones manufactured after the end of March with Android Nougat. Producers are not able to install Google Mobile Services including Google Search and the Play store.
The ban on use of «Nougat» in the new Android smartphones will increase the proportion of devices that support Project Treble, because its presence is one of the certification requirements of smartphones in the Oreo.
Any device that comes with the package of Google Mobile Services, must comply with the requirements determine the compatibility of Google. To motivate manufacturers to upgrade smartphones to the latest version of Android, Google is closing a certification of previous releases. For example, five months after the release of Android 7.0 Nougat stopped certification of new devices on Android 6.0 Marshmallow.
Only Google certified about 16 000 models of smartphones and tablets, Android Oreo of them installed only 5% of devices.
