iOS 11.4.1 goes live, introduces USB Restricted Mode

iPhone X Screen

iOS 11.4.1 is out for all eligible iPhones and iPads, introducing USB Restricted Mode to everyone. The feature works just like it did in the beta build, keeping your device safe from hackers and cops.

To recap, USB Restricted Mode stops USB accessories from connecting to an iPhone after an hour has passed since it was unlocked. It basically shuts down the Lightning Port so it can only be used for charging the handset, not for transferring data. Hacking tools like GrayKey will now only have an hour to try to force their way into an iPhone before the tool throws them out.

How to Toggle USB Restricted Mode

USB Restricted Mode is enabled by default. You can check it out by heading into Settings > Face ID/Touch ID & Passcode. It’s listed as ‘USB Accessories’ and the text below it is worded a bit confusingly for folks not aware of what exactly it does.

If the toggle is off, it means your iPhone will shut down after an hour has passed since you last unlocked it. Your iPhone will thus be protected from hacking machines. If the toggle is on, it means you can connect USB accessories even after an hour has passed. This will allow hacking machines to gain access to your data.

Like we said, the tool is switched off by default, but you can change that if the setting interferes with your activities. Other than USB Restricted Mode, iOS 11.4.1 also includes a fix for an AirPods bug which didn’t allow it to be viewed in the Find My iPhone app.

iOS 11.4.1 will also bring some relief to users with Exchange accounts as it improves the reliability of syncing mail, contacts and notes. You can download the software on your iPhone/iPad by going to Settings > General > Software Update.
