iOS 11.4 release date and news: USB Restricted Mode could make it harder for police to access your iPhone

Apple could soon make it much harder for both criminals and police to get access information from your iPhone, with digital forensics software firm ElcomSoft unearthing an interesting security update in iOS 11.4.

iOS 11.4 release date and news: USB Restricted Mode could make it harder for police to access your iPhone

“USB Restricted Mode” works by disabling your data connection via Lightning port if the phone hasn’t been unlocked for a week. That means if a device has been idle for seven days, you won’t be able to access data using a Lightning cable, and will instead need to get into the device using Face ID or a passcode.

The move will likely cause headaches with law enforcement. Ever since the clash between Apple and the FBI over access to the iPhone of the San Bernadino shooter, there have been reports of agencies using third-party companies and services to bypass the tech company’s security. Hardware like the GrayKey iPhone unlocker  reportedly sells for $15,000 (£11,105) and is specifically used for breaking into locked Apple devices.

The update to iOS 11.4 looks like an effort to thwart those attempts to bypass Apple’s security. When an iPhone is normally plugged into a computer, the devices will communicate with each other to check if they’re authorised to exchange data. This can be taken advantage of by those looking to break into the handset, but Apple’s latest update should make that process much harder to pull off.

For the owner of the iPhone, they probably won’t even know the measures are in place. If they’ve left their phone for a week, all they need to do is put in the password of scan their face as normal, and it will unlock. It’s only those without access to that information that will be frustrated.

iOS 11.4 is expected to be publicly released in a matter of weeks, following four public betas. 

iOS 11.3.1 on iPhone and iPad

25/04/2018: Apple’s latest software update for iPhones and iPads is now live and while it’s a minor update, compared to the relatively far-reaching changes we saw in iOS 11.3, it does come with some important additions. 

Namely, iOS 11.3.1 fixes an issue created by the previous update which saw the screens on certain iPhone 8 models become unresponsive. Specifically, this problem only affected those screens which had been fitted by a third-party. The patch notes address this issue but come with a warning from Apple telling users to avoid “non-genuine replacement displays.”

“iOS 11.3.1 improves the security of your iPhone or iPad and addresses an issue where touch input was unresponsive on some iPhone 8 devices because they were serviced with non-genuine replacement displays,” these notes explain. “Note: Non-genuine replacement displays may have compromised visual quality and may fail to work correctly. Apple-certified screen repairs are performed by trusted experts who use genuine Apple parts. See for more information.”

A security update has additionally been rolled out for Macs, as part of macOS 10.13.4 to fix flaws in a previous macOS High Sierra build.

The iOS 11.3.1 update is the latest in a long line of iOS, and Mac, updates being made as we gear up for the launch of iOS 12 later this year. 

Following the release of the new iPad in March, Apple rolled out iOS 11.3, which featured a number of tweaks and fixes, along with music videos in Apple Music and an icon that let’s you know if Apple is using your personal data. On that latter point, Apple has updated its guidance around privacy and data ahead of incoming GDPR legislation, which is also timely given the current conversation around Facebook’s handling of user data.


The iOS update also includes four new animoji, allowing you to gurn at the camera and have dragons, lions, skulls and bears leer back at you. ARKit gets updated to 1.5, adding support for vertical surfaces like walls, autofocus and a boost on its resolution.

How to install iOS 11.3.1

When the update is available for your phone you will be prompted to install it automatically. It should be noted that the release can sometimes be staggered and may not be available immediately. 

If you are concerned about iOS 11.3.1, it’s also worth downloading the firmware for previous releases, just in case. The full list of files for each compatible iPhone and iPad is listed at the bottom of this article. 

To backup your phone, go to Settings, [your name], iCloud and iCloud backup. You can also backup your device using iTunes. If you choose the latter, it’s worth making sure iTunes is also up-to-date and you can get the latest software here. We recommend you backup certain apps, namely WhatsApp, as it may delete chats. This can be done in Settings, Chats and Chat Backup. 

You’ll need to make sure you have enough room to complete the installation if you install it over the air (OTA), otherwise, it will fail and could, potentially, brick your phone. To clear space, go to Settings, General and Storage to check how much storage is being used and delete unwanted files or apps to make room.
