When your RealMe 16 cannot open PDF files, it can quickly disrupt work, school tasks, or even simple document viewing. You tap a file, nothing happens, or the phone shows an error message. This issue is usually caused by app problems, missing permissions, or a corrupted file, and most fixes are straightforward once you know where to look.
Why Your RealMe 16 Can’t Open PDF Files
- No PDF reader app is installed or the default app is disabled.
- The PDF file is corrupted or not fully downloaded.
- App permissions prevent access to storage.
- The PDF app cache is corrupted.
- The file format is incompatible or damaged.
1. Make Sure a PDF Reader App Is Installed
Your phone needs a dedicated app to open PDF files. Without one, tapping a PDF will either do nothing or trigger an error.
Open Settings, and then tap Apps.
Scroll through the list, and confirm a PDF reader like Google PDF Viewer or another reader is installed.
2. Set a Default App for PDF Files
Even if a PDF reader is installed, the phone may not know which app to use. Setting a default app ensures PDFs open correctly every time.
Open Settings, and then tap Apps.
Tap Default apps, and then select a PDF reader under file or document handling.
3. Check App Permissions
If the PDF app cannot access your storage, it will fail to open files. This often happens after updates or permission changes.
Open Settings, and then tap Apps.
Select your PDF reader, tap Permissions, and allow access to Files or Storage.
4. Clear the PDF App Cache
A corrupted cache can prevent the app from loading documents properly. Clearing it refreshes the app without deleting your files.
Open Settings, and then tap Apps.
Select your PDF reader, tap Storage, and then tap Clear cache.
5. Re Download the PDF File
The file itself may be incomplete or damaged. Downloading it again often resolves the issue instantly.
Open your file manager, and then locate the PDF.
Delete the file, and then download it again from the original source.
6. Try Opening the PDF With Another App
Some PDF files are not fully compatible with certain readers. Using a different app can bypass format issues.
Open the Play Store, and then search for another PDF reader.
Install it, then open the PDF using the new app.
PDF issues on the RealMe 16 are rarely serious. Once you confirm the app, permissions, and file integrity, your documents should open normally again.
FAQs
Why does my RealMe 16 say “File cannot be opened”?
This usually means the PDF is corrupted or your PDF reader lacks permission to access storage.
Can system updates cause PDF files to stop opening?
Yes. Updates can reset app permissions or default apps, which may block PDF access until corrected.
Is it safe to clear cache on a PDF reader app?
Yes. Clearing cache only removes temporary files and does not delete your PDFs or personal data.
