An anonymous reader shares a report on The Verge: Google says that a small number of Pixel phones have broken microphones that need to be sent back for replacement. The issue is seemingly not that widespread. Google claims the issue is present on less than 1 percent of devices -- the company also announced that it would replace defective phones last month, and it went largely unnoticed until now. Google says the primary cause for Pixels having microphone issues is a "hairline crack in the solder connection on the audio codec," which causes all three of the device's mics to go out at once. The issue has apparently been known about for several months now. Google says it's been "taking additional steps to reinforce the connection" since January and that phones built or refurbished since then should be fine.
