Almost a month is what has had to wait for the Nexus 6 p to receive the beta of 7.1.2 Android after which the Pixel, Pixel C and Nexus 5 X received it nothing more starting this month of February.
In the last hours the beta of Android 7.1.2 (NPG05F) It is coming via OTA to the Nexus 6 p that are subscribed to the Android Beta Program, but not everything are good news, a novelty that received the 5 Nexus X who has not reached his older brother.
The Nexus 6 p has not received the gesture of the fingerprint sensor to see notifications they premiered the Pixel and a few weeks ago also became the Nexus 5 X with Android 7.1.2.
At the moment no explanation there about the absence of this gesture in the Nexus 6 p when in the 5 Nexus X if you are implementing, especially when it is assumed that both terminals share the same fingerprint sensor.
Gesture in the fingerprint reader was the most important novelty which had received the Nexus 5 X with this new version of Android. In the Nexus 6 p this version stays in a simple maintenance update. Now it remains to be seen if this gesture ends up coming in a future update.
