Motorola announced in September 2017 that, among many of its phones, the Moto Z would receive the Android Oreo update. About six months later, it looks like the software may soon be seeded to users around the globe.

The anticipated upgrade has made its way to Moto Z owners in Brazil, teasing that Moto is sampling its wares on one region before blasting it out on global basis. The South American country isn’t a typical launch pad for new software, though Moto seems to have just as strong a presence there as it does in any other region.
