Over the years, Apple has increased the level of customization of the iPhone, but it has not been possible for users to change the system wide fonts. Thanks to a new tool created by a developer, users will be able to change their phone's style if they're running an older version of the operating system.

The developer, Zhuowei Zhang, made a tool that changes an iPhone's system-wide fonts by exploiting a security loophole in the past versions of the operating system. The security loophole used to make the tool was patched in the latest version of the operating system, so an older version of the operating system is required to use it.

If you want to know what version your phone is running, you can go to the settings page. If you're running the latest version of the software, you won't be able to upgrade.

Comic Sans, Fira Sans, DejaVu Sans Mono, and others are some of the options that the tool can be used to change the look of the phone. The tool will change the appearance of your phone as shown in the images below.

Important security fixes and a host of new features, including new options for the always-on display on the iPhone 14 Pro, are included in the new version of the operating system. Our guide will show you more about the software.
