According to the Korea Herald, the South Korean military is considering a complete ban on the use of iPhones and other wearables in military buildings due to concerns that uncontrolled recordings will reveal sensitive information. The South Korean Air Force headquarters issued an internal notice on the military's internal network server, instructing that any device capable of recording and not allow third-party applications (apps) to control devices with built-in functions from June 1. The iPhone is also included as a regulated device. The announcement clearly stated that “carrying iPhones will be completely prohibited,” but sources said that Android smartphones (mainly Samsung Electronics' smartphones) will not be subject to the ban. If the scope of the ban were extended to the entire military, it would affect nearly 500,000 South Korean soldiers.
