Motorola is now rolling out official Android 8.1 Oreo OTA update for the Moto G5S and G5S Plus. This is the stable version of the update and not the soak test. We already have Motorola’s Beta soak test for the Moto G5, G5 Plus, the Moto G5S and G5S Plus. Now, the manufacturer is sending push notifications to users about their new stable Android 8.1 Oreo firmware. Luckily, users of Moto G5S Plus have been successful in capturing the OTA update from different regions and share the download links. So download and install Android 8.1 Oreo for Moto G5S and G5S Plus.
The new firmware update for Moto G5S Plus is still based on the August 2018 Security Patch of Android 8.1. The OTA also features a new software version (build number) OPS28.65-36 for Moto G5S Plus as opposed to the build OPS28.85-13 that came for the Moto G5 (Plus). There is not much of a changelog from Motorola as of now. It sure features all the Android 8.1 Oreo goodies, new and updated Moto stock apps, bug fixes, and stability improvements.
On the contrary, Motorola may start recruiting for the upcoming Android 9.0 Pie Beta soak test as well. So you better sign up for Moto’s Soak Test so you get Android P before anyone else. This goes for all the Lenovo-Motorola mobile phones. Meanwhile, update Moto G5S (Plus) to Android 8.1 Oreo via full stock firmware (Fastboot zip) and OTA update zip from the stable channel.
