Pixel 2 voice call clicking (and how you can fix it)
We reviewed both Pixel 2 handsets simultaneously, and while these phones share a lot of hardware and software, the clicking noise only cropped up on the smaller Pixel 2, while voice calls on our Pixel 2 XL sounded just fine.
But they also share in Apple's little voice-call blunder, and in our Pixel 2 review we noted running into a similar clicking-noise issue with voice calls.
We started up a voice call, and the clicking was still there, just like always.
