Authorities are warning iPhone users of one of the features of the newest iPhone update.

The feature called “NameDrop” is enabled by default with the new update. Anyone with this feature can place their phone next to your iPhone or your child’s iPhone and automatically receive their contact information.

Police said information passed to another phone could include a picture, phone number, email address, and more.

Police say to disable the feature, go into your iPhone settings, click general, then airdrop, and shut off “bringing devices together.”
