Apple today released iOS 12.1.2 which carries software changes to address the contentious patent which is involved with their ongoing legal battle with Qualcomm.
The iOS update reportedly fixes issues addressed with the patent, however, Qualcomm says it violates the recent Chinese injunction granted against certain iPhone models. This is because Qualcomm believes Apple is going against the court-ordered injunction to find ways to sell iPhones in China, without explicit permissions to do so.
Earlier reports suggest that the injunction only affects models running an older version of iOS. Apple therefore believes they are in compliance to sell iPhones in China. Apple has stated that iPhones will remain available for users in China.
