Apple is facing a U.S. federal lawsuit that claims it failed to tell its users that switching from an iPhone to Android could cause text messages not to arrive.
U.S. District Judge Lucy Koh, of Apple v. Samsung fame, said on Monday that the iPhone maker must face one disgruntled user in court, who claims the switch interfered with her Verizon contract.
Adrienne Moore claimed in a suit filed earlier this year that switching from an iPhone 4 to a Samsung Galaxy S5 in April caused "countless" messages to not arrive, because Apple's own proprietary iMessage system could not recognize when a user switched to a rival device.
Moore is seeking class-action status, according to Reuters, and unspecified damages.
Koh said in her late-evening decision on Monday that Apple may have violated a California competition law by blocking messages, which the judge said may have been "intentional acts."
