Nexus 6P microphone problems: is noise cancellation to blame?

By Stephen Schenck November 23, 2015, 3:42 pm

The Huawei-made Nexus 6P may be the cream of the Nexus crop this year, but for as strong a showing as the smartphone’s arrival has made, the handset hasn’t been without its fair share of problems. There was uproar over bend damage, not to mention reports of spontaneous glass-crackage, and to that list we now have one more to add, as users post about the problems they’re running into while trying to make voice calls.

Everything may seem fine on the Nexus 6P user’s end, but people they’re calling have reported some serious issues with voice quality. Sometimes the Nexus 6P user may sound extremely distant, or other times practically muted under the roar of background noise. Some users run into these issues when using the Nexus 6P in speakerphone mode, and others notice it varies depending on how they hold their handset.

Google has posted in its support forums that it’s investigating the issue, but for now a cause and solution have yet to be officially announced. One prevailing theory, though, suggests that we’re looking at an issue with the implementation of noise-canceling tech on the Nexus 6P, and that when one of the phone’s multiple microphones is blocked, it somehow gets confused about what it should be doing – and ends up treating the caller’s voice as noise, rather than the other way around.

Hopefully there’s an easy fix, but a lot of noise cancellation is done these days with the help of hardware, so that’s not necessarily guaranteed.
