In the mid of May 2017, Nexus 6 users had a lot of issue after upgrading to Android 7.1.1. Because of this Android had to downgrade the OS from Android 7.1.1 to Android 7.0. It seems that Google was up testing all the bugs on the Android 7.1.1. Later today few Nexus 6 users has received a stable Android 7.1.1 update.
The update is packed in a 368MB file & will receive the OTA update soon. With this update the Nexus 6 users will surely miss the Android 7.1.2 update & also the Android O. After this update, is it possible that Nexus could rollout Android 8.0 update? To know this answer we need to wait for it. At the same time will Android give Android O update to a 2014 model? We can find that out if the release the Orio.
I think this time they won’t have to downgrade the OS again.
