Apple issues urgent alert for millions of iPhone owners to check setting – it’s risky not to

APPLE has issued an important iPhone update that you must install as soon as possible.

It squashes major bugs and includes security fixes – so it's worth updating right away.

The new update went live last night, and is called iOS 16.0.3.

It's available to download for free right now.

"This update provides bug fixes and important security fixes for your iPhone," Apple explained.

To get it, go to Settings > General > Software Update.

If you want to be extra safe, make sure you also turn on Automatic Updates.

The update fixes a number of issues with the new iPhone 14 models.

This includes problems with the camera, volume and calls.

And it also repairs the strange Mail "mailjack" bug that meant certain emails could crash the app.

iPhone iOS 16.0.3 patch notes

Here are the official Apple patch notes for iOS 16.0.3...

• Incoming call and app notifications may be delayed or not delivered on iPhone 14 Pro and iPhone 14 Pro Max
• Low microphone volume can occur during CarPlay phone calls on iPhone 14 models
• Camera may be slow to launch or switch between modes on iPhone 14 Pro and iPhone 14 Pro Max
• Mail crashes on launch after receiving malformed email

Not all iPhones are made equal

Apple can't support all iPhones forever – so very old iPhone models often lose access to updates.

Sometimes these old iPhones don't have the power to support new features, or not enough people are using them to warrant providing an update.

Now the iPhone 6S, iPhone 7 and 1st-generation iPhone SE will be cut off by Apple.

These handsets were compatible with 15.6.1, but won't get iOS 16.

If you're using older iPhones than that, you're already cut off, so you should upgrade to a newer model immediately.

Here's the full list of iOS 16 supported devices:

• iPhone 14
• iPhone 14 Plus
• iPhone 14 Pro
• iPhone 14 Pro Max
• iPhone 13
• iPhone 13 mini
• iPhone 13 Pro
• iPhone 13 Pro Max
• iPhone 12
• iPhone 12 mini
• iPhone 12 Pro
• iPhone 12 Pro Max
• iPhone 11
• iPhone 11 Pro
• iPhone 11 Pro Max
• iPhone Xs
• iPhone XS Max
• iPhone XR
• iPhone X
• iPhone 8
• iPhone 8 Plus
• iPhone SE (2nd generation or later)

Not being able to get the latest iOS means you'll lose access to the most up-to-date security fixes.

These are vital patches that close holes used by hackers to access your systems.

So using a very old iPhone that can't be updated could put you at risk.

If you can't update to iOS 16, consider upgrading your iPhone sooner rather than later.
