In this video, I’ll show you how to change the default PDF viewer on your Android phone.

If your phone automatically opens PDF files in the wrong app, I’ll show you how to reset the current default. Then, when you open a PDF again, you’ll get the option to choose which app to use — either just once or set it as the new default.

You’ll learn:
• How to clear/reset the default PDF app
• How to trigger the “Open with” selection screen
• How to choose a new default PDF viewer
• The difference between “Just once” and “Always”

This works on Samsung phones and most other Android devices.
