Google Huawei Nexus 6P users have complained about poor call quality, and muffled voice when using the phone. Google’s product forum is filled with quite a few of these complaints from users. User complaints about low-quality calls have been posted on XDA Developer forums as well.
Additionally on XDA, users have also complained about the Nexus 5X becomes unresponsive when it is being charged. According to the complaints on the forum, the scroll/swipe speed appears to be much slower on the Nexus 5X and there’s a visible lag on the device. Users have added that the issue is worse the device is on charging, with some calling the phone ‘unusable’ when its on charging due to the lagging problem.
With Nexus 6P, one user Jamie Corbett posted on the Google Product Forum that he faced the issue of muffled voice quality while using the headset, but on speaker the calls would sound okay.
Another user Samuel Biehl noted that in his case “the calls are initially almost silent to the party I am speaking to… and it sounds like I am very far away. The quality changes a lot sometimes for the better sometimes for the worse if I cover the back Mic.” Users have also reported that the speakerphone option is not working with VoIP apps like Hangouts or Skye.
A lot of user reports note that the covering the rear-microphone, (the one for noise cancellation) causes the problem but for some the opposite is true, i.e. covering the mic actually fixes the issue.

On XDA Developers forum users have also noted that they need to put the microphone right next to their mouths for anyone to hear them when on a call and that the issue persists even if they are in quieter environment.
Another comment on XDA by a user puts the blame on aggressive noise-cancellation and says that a software update could fix the issue and it might not be a hardware problem at all.
On the Google Product Forum, Google experts have replied saying that they are investigating the issue and working on a fix. Google’s experts have said they will reach out to a few customers in order to get bug reports as well.
