Apple this morning announced a new feature in iOS 12 which will automatically share your location with first responders when U.S. users dial 911 using their iPhone. The move is meant to address the problems with dialing emergency services from a cell phone, where outdated infrastructure has made it difficult to obtain a mobile caller’s location quickly and accurately, Apple says.

Approximately 80 percent of 911 calls come from cell phones, however, which is why it’s critical to fix this system.
