The Lenovo-owned mobile company, Motorola was one of the early birds when it came to delivering the Android 8.0 Oreo update. We had earlier reported that the Android 8.0 update for the first-generation Moto Z was being soak tested in Brazil.
Based on the latest update directly from a user, the second soak test OTA is rolling out for the Moto Z. XDA member kvilpura has reported that Motorola is pushing out the second phase of its Android Oreo soak test for the original Moto Z.
The new update comes with the latest February security patch from Google, along with some newly added features. The latest soak test update comes with the brand new Moto Launcher, replacing the stock Google Now Launcher. This includes redesigned app icons, notification dots, and a new clock widget.
Bug fixes and improvements in system stability should be expected, but since it is a soak test (beta) update, don’t expect it to run smoothly. Based on the discussion, it seems like the new software version OPN27.76-12-2/4 can only be installed on Moto Z devices on build version OPN27.74/28.
If you simply cannot wait any longer to taste Oreo on your Moto Z, you can flash the OTA update, at your discretion of course. We do suggest that you wait a little longer for the public release, or the beta testing of the Android 8.0 update to begin in your region.
