Among the list of Pixel 2 issues uncovered shortly after its launch, was one that resulted in poor audio quality in recorded videos. The problem was officially acknowledged, with Google saying a fix is incoming.

And here it is - the fix is included in the latest Android 8.1 developer preview. The following videos clearly show the problem has been taken care of - first one is made with a Pixel 2 unit running Android 8.0 and the next with a phone running Android 8.1 DP2.

It's worth mentioning that not every Pixel 2 unit out there is running developer preview builds, so it'll still take sometime for the fix to arrive for everyone, something which will happen with the public roll out of Android 8.1. For now, at-least those tracking Pixel 2 issues can strike off this one from their list.
