Assess if you need a dedicated PDF viewer for advanced document tools or if basic built-in viewers are sufficient.

Apps like Adobe Acrobat Reader provide robust tools for general users, making it easier to share, print, and save files securely.

If you require more than basic viewing, open the Google Play Store, search for a dedicated PDF reader like Adobe Acrobat Reader, and tap 'Install'.
Once installed, open a PDF file from your phone's file manager. When prompted to 'Open with', select your newly installed PDF app and tap 'Always' to make it your default viewer.
