Some noticed it immediately after buying the Pixel 2 XL, while others experienced it out of nowhere. This one bears a relation to Bluetooth, one of the Google Pixel's old nemeses, but it's an issue that's unlikely to disrupt too many users. The right earbud not only awakens Google Assistant, it also activates the cool real time Google Translate feature.
Fast Pair in particular is an awesome feature that's now available in only select few Made for Google headphones: Google Pixel Buds of course, Libratone's Q Adapt On-Ear, and Bose® QuietComfort 35 II.
According to a discussion on one of Google's Product Forums the Pixel 2 microphone does not work in some critical scenarios which include while the user is on a call or when the Google Assistant is functioning.
The Pixel 2 XL's panel has become pretty notorious at this point, with people complaining about a blue light shift, dead or colored pixels, non-vibrant colors, and screen burn-in. Additionally, some Pixel 2 and Pixel 2 XL users are reporting problems with their handsets' microphone. Even though Google said it is working on a permanent fix for the problem, a simple technique of blowing into the bottom speaker is resolving the issue. A user has reported that whenever the phone is unlocked a flashing screen appears before the display turns up. Doing this made my microphone work again and it continues to work when it goes out. Blowing into the speaker like you would an old NES cartridge.
Pixel 2 prices start at $17.60 and $20.31 with 35 and 25 percent discounts respectively, while the Pixel 2 XL still fetches at least $23.01 and $26.91. Unfortunately for Google, the issue seems to have plagued quite a few users and seems like a hardware issue rather than a software problem.
