How to Fix Screen Lines and Phone Shutdown When Opening PDFs on Android
Question details
The user's mobile device displays horizontal screen lines and unexpectedly shuts down when attempting to open PDF files in a third-party PDF reader.

- Product
- Adobe Acrobat Reader Mobile
- Device & OS
- OnePlus 9R 5G (Android)
- Scenario
- Attempting to open and view standard PDF documents using Adobe Acrobat Reader on an Android mobile device.
- Observed behavior
- Upon opening a PDF, horizontal lines appear on the screen, immediately followed by the phone shutting down entirely. The issue resolves when the application is uninstalled.
Ensure your device has sufficient battery charge, and try opening a plain text file to confirm the display issue is strictly related to PDF rendering.
Update Apps, OS, and Clear Background Conflicts
Resolve compatibility bugs and rendering overload by ensuring your operating system and application are fully up-to-date while minimizing background resource usage.
Screen glitching and device shutdowns during PDF rendering often indicate a severe resource conflict, outdated graphic drivers tied to the Android version, or a buggy app update.
Clearing the device's operational environment before launching the app can prevent system overloads.
Go to your device 'Settings', navigate to 'System' or 'About device', and tap 'Software update'. Download and install any available updates for your OnePlus device.
Open the Google Play Store, tap your profile icon, select 'Manage apps & device', and check for updates for Adobe Acrobat Reader.
If you are running a VPN service, open the VPN app and tap 'Disconnect', as network interception features can sometimes conflict with mobile app loading sequences.
Tap the recent apps button on your device's navigation bar and swipe away all running applications to free up RAM before opening your PDF.

Isolate the Issue Using an Alternative Viewer
Determine if the issue is with the specific PDF file or isolated to the Adobe Acrobat app by opening the document in a different viewer.
Record the Glitch and Contact Support
If standard troubleshooting fails, gather specific diagnostic data and escalate the issue to the software developer for a targeted patch.
Read and Edit PDFs Safely with WPS Office

Frequently Asked Questions
Why does my Android phone screen show lines and shut down when opening an app?
This severe reaction is typically caused by a hardware-level rendering failure. When a specific app requests graphic resources that conflict with the device's GPU drivers or Android version, it can trigger a kernel panic, resulting in visual artifacts (lines) and an automatic protective shutdown.
Can a corrupted PDF file cause my mobile device to crash?
Yes. If a PDF contains malformed code, incredibly high-resolution uncompressed images, or complex vector layers, a poorly optimized PDF reader may overwhelm the device's memory trying to process it, leading to a crash or shutdown.
How do I stop my default PDF reader from crashing my phone?
First, completely uninstall the problematic app. Next, clear your device's cache. Finally, install a more stable, lightweight alternative like WPS Office, which handles PDF files using better memory optimization to prevent system overloads.
