One of the nice things about modern smartphones today is that they’re easy to track if you lose them, provided you have a service like Apple’s Find My iPhone or Google’s Android Device Manager running in the background. If you leave a phone in a taxi, for example, you can pull up a map and spot where it ends up. Or, if it’s stolen, let authorities know the device’s exact location. iOS 7.1, however, has a major bug that allows would-be thieves to turn off the feature entirely.

A video on YouTube describes how the flaw works, where someone is able to delete an iCloud account — essentially stopping it from tracking the device using Find My iPhone. That means, if you have your device stolen, someone can prevent Find My iPhone from working properly and you won’t be able to track it online or from another device using your iCloud account.

We won’t dig into how to do it, but as the video shows it’s relatively easy for a deliberate individual to do. Thankfully, you can prevent this from happening by making sure that you always use a passcode lock on your phone — something you should definitely be doing already.
