Observed behavior

Solution 1Recommended

Clear Default App Settings

Use your device settings to remove the 'Always' preference from the incorrectly assigned application.

When you select 'Always' while opening a file, your device assigns that app as the default handler for that specific file type. To reverse this, you must clear the default permissions directly from the app management menu.

1
Open Device Settings

Navigate to your device's home screen or app drawer, tap on 'Settings', and locate the 'Apps' or 'Applications' menu.

2
Locate the Incorrect App

Scroll through the list of installed applications and tap on the app that is currently opening your PDFs by mistake.

3
Clear Defaults

Tap on 'Open by default' or 'Set as default' within the app's info page, then select the 'Clear defaults' button.

4
Select a New PDF Reader

Navigate back to your files and open a PDF document. When prompted, select a proper PDF reader such as WPS Office and choose 'Always' to establish your new default preference.

Clear Default App Settings
Defaults Cleared Successfully: Your device will now prompt you to choose an application the next time you attempt to open a PDF file.

Frequently Asked Questions

Why does my device no longer ask me which app to use when opening a PDF?

This happens because an application was previously granted the 'Always' permission to handle PDF files. You must clear this default setting in your device's App Management menu to restore the selection prompt.

Can I change the default PDF viewer on a Windows PC?

Yes. On a Windows computer, right-click a PDF file, select 'Open with', click 'Choose another app', select your preferred PDF reader like WPS Office, and check the box that says 'Always use this app to open .pdf files'.

What if the 'Clear defaults' button is grayed out?

If the button is grayed out, it means the application is not currently set as the default for any actions. Double-check your app list to ensure you have selected the exact application that is improperly opening your PDF files.

Will clearing app defaults delete my PDF files?

No, clearing default app settings only resets the system's preference for which application opens a specific file format. Your actual PDF documents and internal app data remain completely safe and untouched.
