Apple's iOS 10.3 update, which was released this week, has reportedly resolved a 911 flaw. At issue was an iPhone feature allowing users to click on a phone number to immediately start a call.
The update requires folks to now always press a 2nd confirmation. In October 2016 a teenager allegedly designed code that would cause iPhones to repeatedly dial 911. The code went viral, and teenagers all over began using it as a prank, overwhelming 911 call centers in numerous states.
