Snapchat's new feature allows friends to pinpoint your exact location - and what you're doing.

Parents in particular have been warned to ensure that their child’s settings on Snapchat are on ‘ghost mode’ as the latest update for the app allows friends to pinpoint your exact location.

Your location will not be hidden automatically following the new update, so users will have to open the map and manually disable the location-sharing feature.

To turn on ghost mode, open the map and click the settings button on the top right hand corner and enable ghost mode.

How does it work?
When you open your camera, pinch your fingers as though you’re zooming out of a photo. The Snap Map will appear and allow you to see your friend’s Bitmoji and where exactly they are.

Weirdly, Snapchat have turned your Bitmoji (personalised avatar) into an Actionmoji, which changes your avatar depending on what you’re doing. If you’re listening to music, your Actionmoji will be wearing headphones. If you’re driving, your Actionmoji will appear in a car.

A Snapchat spokesperson says “Snapchat may look at things like your location, time of day, or speed of travel. Examples of Actionmojis today include things like: at the beach, at the airport, sitting, and a handful more.”

Snapchat have also included a heat map for their ‘our story’ feature, while allows people at various events to curate a public story together. Blue means a few snaps have been taken, with red meaning a lot have been taken.

Speaking about the update, Snapchat say “We’ve built a whole new way to explore the world! See what’s happening, find your friends, and get inspired to go on an adventure!”

They add; “Actionmojis only update when you open Snapchat.”
