In the Nexus family, the Nexus 6 from 2014 is the only eligible Nexus device which is yet to receive Android 7.1.1 — but with Google’s recent statement, it’s about to change.
Google has confirmed Android Police that a last minute bug halted the OTA rollout, stating:
“Unfortunately, we found a last minute bug that was specific to the Nexus 6, which has caused the delay of the 7.1.1 OTA rollout. We’ve since fixed the issue and will be rolling out an update in early January.”
The Android 7.1.1 OTA update brings Pixel-exclusive features to other Nexus devices, including app shortcuts, new emoji, enhanced live wallpaper, and more.
