The new iPhone software update, iOS 18.4, could be more critical than is being talked about when it comes to security.

While there are lots of new features added in the latest release, out yesterday, what’s less talked about is the 62 security updates and fixes that roll out with this version. Some are quite serious.

Apple doesn’t make a big deal about these fixes as the plan is to keep them under the radar to stop attackers finding vulnerabilities or knowing when doors are closed to their attacks. Ultimately it’s a choice to help protect iPhone owners for as long as possible from the update rolling out.

Looking more closely at the iOS 18.4 update reveals there were some serous flaws that could leave current older software users at risk.

Some of the patches were found in WebKit, for Safari, and the Kernel at the heart of the iPhone operating system.

The fixes stops the possibility of a malicious app being able to attempt passcode entries on a locked device.

On websites there was the chance that a cross-site scripting attack could leave users vulnerable. This would allow attackers to inject malicious scripts right from trusted websites.

Why update to iOS 18.4 now?

Since all these patches are now publicly available it means attackers can see, even more clearly, the vulnerabilities in older versions. These are likely the devices that will be attacked now.

Since Apple has fixed more than 60 issues in one update, that means this is a big security shift – showing just how vulnerable older versions may be.

How to update to iOS 18.4 now

If you have an iPhone that’s the iPhone Xs or newer then this update applies to you and is available now.

To upgrade your software simply navigate to your Settings menu, then select the General tab and then Software Update. This will give you the option to download and install the iOS 18.4 update with a restart to let everything take effect. Then open up like you’re starting your brand shiny new iPhone.

New iPhone 17 Pro render keeps us guessing on the final design
Apple iPhone 17 Pro Render

Apple is to expected to announce the iPhone 17 series later this year, likely sometime in September if previous release patterns are anything to go by. By our calculations, that puts us around five months out, though math is not our strong point – we're writers here after all. 

What we do know however, is that in the upcoming months we are no doubt going to see more conflicting rumors about what we can expect from the iPhone 17 and iPhone 17 Pro models in terms of design. A few months back, it was suggested the iPhone 17 Pro models would feature a new camera bar across their rear, taking on a more Pixel-like approach.

Foldable phones have been around for over five years now and there are several options available. It's not just Samsung and Google in the folding space, but Motorola, Huawei, Oppo, OnePlus and Honor too. There is one company notably missing however, and that's Apple. 

The company has long been rumoured to be working on a folding iPhone, and there's talk of a larger folding device too. Both are speculated to enter mass production in late 2026 with a launch then happening towards the end of next year or early 2027.

Android phones get new security feature that iPhone owners already have

Google is taking a page out of Apple's playbook by launching a new security feature that makes Android phones automatically restart after a few days of inactivity.

The new auto-restart feature (or auto-reboot, if you want to call it that) was patched into the latest Google Play services update, which was released on Monday. The release notes say that the update forces your Google Pixel 9, Samsung Galaxy S25, or other Android phone to restart itself "if locked for [three] consecutive days," which means you need to enter your PIN code if you want to unlock it after not using it for that period of time. It resembles the Inactivity Reboot feature on iOS 18.1, only iPhones would restart themselves after four days.
