In this video, I show you how to change the default PDF viewer on your Android and Samsung phone or tablet. In this tutorial, you will learn how to set your preferred PDF reader app as the default, adjust your default app settings, and switch which application opens PDF files automatically on your Galaxy device. This means you can open every PDF with the viewer you actually want, without being prompted to choose an app each time.
