They are some of the world’s most popular smartphones.
And if you are an iPhone user, be sure to update your device today.
Apple has released iOS 18.2.1 for the iPhone and recommends downloading it immediately.
According to the tech giant, this update ‘provides important bug fixes and is recommended for all users’.
This is the first big software update of 2025 and comes alongside the new iPadOS 18.2.1 for Apple’s tablets.
It comes just one month after the release of iOS 18.2 which brought a localised version of Apple’s AI features, known as Apple Intelligence, to the UK.
Although this update won’t contain any new features or critical security fixes, it is still recommended for all users to make sure your iPhone works as intended.
Here’s how you can install it on your smartphone.

According to Apple, this update contains fixes for some of the bugs that appeared with iOS 18.2.
Although the company doesn’t specify which bugs are being addressed, iPhone users have reported experiencing several frustrating issues.
Some users say that group chat notifications have been showing up even when alerts are set to hidden.
Likewise, several Apple fans on Reddit say that they have found an unexplained ‘grey horizontal line’ appearing in the Pictures app since the update.
Others report a number of issues with Apple’s Car Play feature, which allows some cars to display the iOS screen while driving.
Users say their devices struggle to connect to the car, fail to display album or song artwork on the homescreen, and even experienced crash unexpectedly.
One frustrated Reddit user wrote: ‘I’ve been dealing with iPhone issues for a while now and it’s just getting worse.
‘I’ve been experiencing lag, apps freezing or crashing, and even the keyboard randomly becoming unresponsive. These issues have been happening more frequently lately and it’s really starting to get on my nerves.’

However, Apple hasn’t provided any specific information on the bugs, so it isn’t yet clear if any of these issues have been addressed.
Another detail which is conspicuously absent from the update is any mention of security.
Typically, smaller updates contain fixes for security issues which Apple has identified since the last big release.
For example, the earlier iOS 18.1.1 update contained ‘important security fixes’ for weaknesses which hackers had already been actively exploiting to hijack iPhones.
Apple doesn’t always disclose its security changes until users have had a chance to download them, to avoid tipping hackers off to potential weaknesses.
But with no mention of security in the update it is unlikely that iOS 18.2.1 contains any vital changes.
For bigger changes, Apple fans will need to wait for the release of iOS 18.3 which is expected within the next few months.
Based on a public Beta which was released last week, this update should bring some changes to the calculator app, support for robot vacuums in the Home app, and dark mode options for more apps.

How to install iOS 18.2.1
The update is compatible with all iPhone models that can currently run iOS 18.
That means all models from the iPhone XS onwards will be able to install iOS 18.2.1, including the second and third-generation iPhone SE.
To install the update, open the Settings app on your iPhone.
If you have automatic downloads enabled, the update will have been installed overnight provided your iPhone was charging and connected to Wi-Fi.
But, if that isn’t the case, you should see a notification reading ‘Software Update Available’ from the Settings homepage.
Tapping this notification will bring you to the Software Update page, where you can see any new updates as they are released.
If iOS 18.2.1 is available, simply select ‘Install Now’ to begin.

If the option reads ‘Download and Install’, tap it to download the update, enter your passcode, and then tap Install Now.
To find the Software Update page when there is no notification, select the tab marked ‘General’ and tap on ‘Software Update’.
From there, you can also set future updates to automatically install by going to ‘Automatic Updates’.
Simply set iOS Updates to automatically install and download to ensure you always have the latest software.
