Apple has released iOS 11.4.1, a new version of its mobile operating system, which among other small updates, contains a feature that locks the Lightning port after an hour of inactivity. Once the hour has passed, any accessory connected to the port requires a passcode to be entered before it will operate.
Called USB Restricted Mode, it’s a controversial change because it will effectively end the chances of anyone using the port to bypass the phone’s security system and view the contents, which happens to be the most common way for law enforcement to access a device.
Plug in a USB accessory that doesn’t simply charge the iOS device after an hour of non-use, and you’ll be required to unlock it before the two will talk to each other. Other than USB Restricted Mode, iOS 11.4.1 also addresses AirPod location issues, improves Exchange connections, and fixes bugs.
The release is available now for compatible iPhone, iPad, and iPod devices.
