Nexus 6 receives another Android 7.1.1 Nougat update to fix a major issue
7.1.1 Nougat but wasn't successful. The new Android 7.1.1 Nougat update that's now rolling out to the Nexus 6 devices at T-Mobile is meant to fix a certain bug that prevented some users from updating to this version.
It's worth mentioning that Google has already listed the factory and OTA images online, so if you did not yet manage to update your Nexus 6, you can now manually do so by downloading these images.
Also, it appears that the update is available for Nexus 6 on other carriers in the US as well, so it may not be limited to T-Mobile units. No new features or improvements are available in the update, as Google even kept the October security patch for this new Android 7.1.1 Nougat build.
