For those who are wondering about Google’s actions, a community manager has recently posted onto Reddit confirming that the downgrade is indeed happening. The post reads, “There was a recent OTA update for Android 7.0 that is causing confusion for some Nexus 6 users. For those of you that want to guarantee future OTA updates, you will need to get back on the 7.0 supported track. If you are experiencing issues after accepting the 7.0 update, please factory reset your device to help resolve any problems.”
The community manager adds, “For any Nexus 6 users that want to continue flashing/sideloading future builds, you can stay on 7.1.1 and continue to do so.” Unfortunately what Google failed to do is explain why the downgrade was even happening in the first place. Like we said it can only assumed that there were problems with Android 7.1.1 thus the rollback to Android 7.0, but exactly what those problems are remains unclear, but this is probably the closest we’ll get to an explanation for now.
