A former iPhone user sued Apple claiming the company’s messaging system interfered with delivery of texts after she switched to an Android-based smartphone. Apple’s iMessage retains text messages sent from other users of Apple devices and won’t deliver them to her Samsung phone running on Google Inc.’s Android operating system, Adrienne Moore said in the complaint filed yesterday in San Jose, California. People who replace their Apple devices with non-Apple wireless phones and tablets are “penalized and unable to obtain the full benefits of their wireless-service contracts,” according to the complaint. Apple, based in Cupertino, California, has battled smartphone manufacturers in court, most recently in a patent lawsuit against Samsung in San Jose. Apple accused Samsung of infringement based in large part on its use of Android-based features.
