A federal judge in San Jose has certified a class of iPhone 4 and iPhone 4S owners in California who, because of a software glitch, lost the ability to use the FaceTime feature to make video calls.

The lawsuit was filed in the wake of what U.S. District Judge Lucy Koh of the Northern District of California, who is overseeing the case, has termed the “FaceTime Break” after FaceTime stopped working on iPhone 4 and iPhone 4S devices that used iOS 6 or earlier operating systems in April 2014. Plaintiffs claim they were left with a catch 22 of either upgrading their operating systems with software their phones weren’t equipped to run efficiently or to keep their existing software and lose the use of FaceTime.
