The same San Francisco law firm that recently settled arbitration claims against LG over the “bootloop” issue has now filed a new proposed class-action lawsuit against Google. This time, the firm is alleging manufacturing defects in the microphone on Pixel and Pixel XL handsets.

The firm’s clients—Patricia Weeks of Florida and Waleed Anbar of California—say that they both purchased Pixel phones in 2016. However, months after their purchases, they both said that they experienced a defective microphone. The case, Weeks v. Google, was filed Tuesday in federal court in San Jose, California.

When they approached Google’s customer service, they were told that Google would not refund them or offer a replacement.
