Android 10 has been around for little over a month, and it’ll be some time before most eligible devices get to run it. It is common for OEMs to roll out a major software update for a smartphone more than a year after it was first released, as demonstrated by the LG G6. In one instance, users had had to wait for over fifteen months before a build was tested, let alone rolled out. Fragmentation is and will continue to be, the bane of Android’s existence for the foreseeable future, and to be honest, there is only so much that can be done about it. XDA Developers looked at Google’s documentation and found out that all devices released after January 31st will have to run Android 10 to get Google’s stamp of authority.

Common sense dictates that Google requires newly released devices to run the latest version of Android, but the above measure is essential, as a lot of OEMs (especially one that rhymes with Naomi) often try to get away with shipping older software on their devices. Google’s document outlines the deadlines in which OEMs/ODMs can submit software builds to Google to get approval for GMS distribution where GMS stands for Google Mobile Services. It is a package of Google apps, services such as the Google Play Store, and Google Play Services that make up the quintessential Android experience we know and love.
