Customers of the all-new Huawei-made Google Nexus 6P owners are reportedly experiencing some issues related to the rear camera and some other reporting of the device microphone, which create low-quality sound. Problems may related to noise cancellation that which Google is investigating on.
Several threads have been posted on the Google Product Forum and XDA Developers about these issues, a common among them is early adopters seems to be weak and spotty voice quality, where the voice of the Nexus 6P owner, not the other call party, either side. With a very similar problems, both the sites are filled with issues, both in standard call mode and when using the speakerphone. So Google representatives have although responded on the official forum, and say that they’re working on it to fix.
It looks like the problem may stem from the phone’s noise cancellation setup. Based on some unofficial experimentation by users, most modern smartphones use multiple microphones in addition to the primary “mouth” mic in order to screen and filter out surrounding noise for a clearer call. It’s said that intentionally covering the rear microphone on the Nexus 6P fixes this issue, but other clarified that it actually causes the problem.
According to one poster on Google forum, Nicholas Fitchett – says that disabling noise cancellation entirely through a root-level build.prop modification worked for him.
I turned off noise cancelling via build prop and it fixed it for me. This goes back to the nexus 5 and nexus 6 as well. I doubt its a hardware issue. Google really needs to enable a setting for this or use better software.
Hopefully, Google can fix the issues on Nexus 6P with a software update in the not-too-distant future. Stay tuned!
