Android 7.1.2 Nougat update breaks fingerprint sensor for many Pixel and Nexus users

In any case, Google must replicate the bug before trying to find a solution. Luckily, there are many Pixel and Nexus users who have taken it to the user community forums to complain (and explain) that their fingerprint sensors are not working any longer after upgrading to Android 7.1.2 Nougat.
At the moment, the issue affects both the Pixel and Pixel XL smartphones, as well as the Nexus 5X and Nexus 6P. The cause of the problem hasn't been identified yet, and there's no workaround to make the fingerprint sensor work again.
