The Google handsets that have started to receive the Android Security Update include the Nexus 5X, the Nexus 6P, the first generation Pixel handsets - the Google Pixel and the Google Pixel XL and the newer phones the Google Pixel 2, and the Pixel 2 XL.
The issue as explained in the lawsuit reads, "The defect compromises the phone's core functionality, preventing consumers from communicating by voice call and from using features like Google Assistant".
"It promoted the Pixel phones as premium products and priced them from $649 to $869".
"Yet, immediately after launching the phones, customers complained directly to Google of "severe microphone issues". Further, it argues that "Despite receiving hundreds of complaints shortly after launch-and admitting the phones have a "faulty microphone"-Google continues to sell the Pixel phones without telling purchasers about the microphone defect".
An AndroidCentral report that yet another lawsuit has been filed against Google in the same week.
In addition, representatives posted on the customer service forums [website], and suggested that the defect was caused by "a hairline crack in the solder connection on the audio codec". The search giant also said that only 1% of its Pixel devices sold were affected with this hardware problem.
Some customers who bought Google's first Pixel smartphone have had buyer's remorse, so much so that they've filed a lawsuit against Google. Ars Technica made the complaint publicly accessible over on DocumentCloud, and notes that both of these plaintiffs purchased Pixel devices in 2016, only to encounter defective microphones a few months later.
One of the advantages of having phones from Google's Nexus and Pixel line-up is the fact that your device is nearly always among the first to receive fresh updates and patches. It also claims that some of the units issued under the warranty replacement program continued to have the same issue.
Fortune has reached out to Google and will update this story with its response if it provides one.
