The lawsuit was filed after Facebook acknowledged it had been logging some Android users' call and text history, but noting it was with their permission. The feature, which allows Facebook to see when a call or text was sent or received, "has always been opt-in only," Facebook said Sunday.

The lawsuit, filed by three Facebook users in a Northern California federal court, accuses Facebook of violating several state laws and acts, including the California Constitutional Right to Privacy, the Computer Data Access and Fraud Act and the California Consumers Legal Remedies Act.
