iOS 7 has bugs not unlocked to make phone calls

Apple iOS was launched on the 7th, and many netizens discovered that this operating system has a program loophole. Karam Daoud from Ramallah, Palestine uploaded a short video to a foreign website to demonstrate how to make a call without unlocking it. Dooota chose to dial an emergency number in a short video and entered a regular mobile number, and then pressed the dial-out button, which enabled him to answer the phone without answering the lock. Some users who saw the video tried to dial with their own iPhone 5 (has downloaded the iOS 7 system), but the same situation did not occur, but a German netizen said that the same situation occurs with the iPhone 4S (has downloaded the iOS 7 system).
