Google Pixel 2 now has a microphone issue31
Complaints were posted on the Google Product Forum, where some Pixel 2 users passed along what they were told by Google. The search giant puts the blame for the microphone problem on an "internal software malfunction" and are reportedly willing to replace Pixel 2 units that have the bug.
Apparently, there is a fix that might bring your microphone back. Simply blow on it. Yes, it works for NES and Game Boy cartridges, and it just might save your Google Pixel 2. So before you agree to replace your device, you might want to see if your breath can bring the microphone back to life.
Keep in mind that there is a law firm trying to sign up Pixel 2 and Pixel 2 XL owners for a class action lawsuit related to other issues with both models. And just so you know where to direct your anger to if you are a Pixel 2 or Pixel 2 XL owner, the latter is manufactured by LG while the former is produced by HTC. And it wouldn't hurt to let Google know how you feel as well.
