Apple’s iPhones are to blame for more than 700 911 calls made without their owners knowing, according to one north Wisconsin sheriff. And that number is for this calendar year alone.

The issue? The iPhones are having their Emergency SOS feature triggered by accident when people are riding ATVs or out in their boats, the county’s dispatch supervisor believes.

As reported by local news, the Langlade County Sheriff’s Office says that more than 159 identical 911 calls were received in June alone.

The Emergency SOS feature is triggered when a device’s side button is pressed five times in succession, and it seems people bouncing around in vehicles is enough to do exactly that.

The Sheriff’s Office says people riding in trucks, ATVs and boats have accidentally hit their button five times, triggering the calls.

Anyone who has this happen to them is advised to stay on the line so they can assure call handlers that they are fine and that the call was a mistake, the report goes on to say. However, action will be taken if the accidental calls appear to originate from one individual more than they should.

The Emergency SOS feature is one of the best iPhone safety features the device offers. It’s just a shame it seems to be causing call handlers problems, especially when they’ve got better things to do than deal with accidental calls.
