Your device has built-in assumptions about which app should open each type of file. When you click a photo, your phone automatically launches the photo viewer. When you open a link, your browser appears. These connections between file types and apps are called file associations, and you can change them. Understanding how to set your preferred apps—and why you might want to—gives you more control over your digital experience and can affect which companies see your activity.
The articles here explain how default apps work across different devices, why you might want to change them, and what happens when you do. You'll learn how to set your preferred browser, email client, or messaging app, and understand the practical differences between your options. We also cover what to watch for when apps request permission to become your default, so you can make choices that match your actual needs rather than just accepting what came pre-installed.
