A XDA user "XDASNR" has managed to capture all the Moto X Play Soak Test OTA(s), meaning that owners of the Moto X Play can install the update right now if they wish to (link to XDA post at the bottom of the page). But before you do, there are a few things to consider-
XDASNR has stated that this update can only be flashed on Moto X Play Indian variant with build MPDS24.107-70-1-5/5 (Download link). Note that this OTA file is for the Moto X Play, so do not attempt to flash it on other devices.
There are total 5 Soak Test OTA files available for the Moto X Play. The developer states that you need to Install all of them one by one in order to get the latest Android 7.1.1 Nougat with September Security patch, new icons, and BlueBorne Fix.
The BlueBorne vulnerability was discovered only recently. It’s a Bluetooth vulnerability that leaves Android devices open to a potential takeover by hackers. The vulnerability is also present in Windows, Linux and some iterations of iOS.
We recommend you to wait for the official OTA, as Motorola is about to push the official update.
