Fix CamScanner Crashes on Android in 2025

If you use the scanning app CamScanner on your Android phone but keep encountering unexpected shutdowns or freezing, you’re not alone. In this article you’ll find clear, effective techniques to fix CamScanner crashes on Android in 2025—covering everything from permissions and updates to cache clearing and device-compatibility tips.

Why CamScanner app might crash on Android

Crashes often happen when the app runs out of memory, conflicts with system updates or hits corrupted files. According to general Android-app-error guidance, you should check storage, software updates, and permissions. Lifewire+1
Because CamScanner has many moving parts—camera access, file saving, PDF conversion—the chances of a crash are higher if one of those fails. Therefore, understanding the causes helps you fix CamScanner crashes on Android much more efficiently.

Pre-troubleshooting: backup and basic steps

Backup your scanned documents

Before you attempt any fixes, export or backup your important PDFs and scans. That way you protect your data while you work through the troubleshooting steps that help fix CamScanner crashes on Android.

Restart your device and update the app

Often a simple reboot clears temporary issues. Next, go to the Google Play Store and update CamScanner to the latest version. Older versions may have bugs or incompatibilities. Later in this article you’ll see how updates help prevent further crashing.

Check Android OS version and storage

Make sure your Android system is updated, and that you have ample free storage (at least several hundred MB free) so the app has room to operate. A lack of storage often causes app instability. Gadget Bridge
After these basics, you’re ready to dig into more targeted fixes to fix CamScanner crashes on Android.

Clear cache, app data and review permissions

Clear cache to remove corrupted temporary files

Go to Settings → Apps → CamScanner → Storage, then tap Clear Cache. This clears temporary files that sometimes cause instability. This is one of the most effective steps to fix CamScanner crashes on Android.

If issues remain, clear app data (with caution)

Clearing app data resets the app to its default state, but you may lose local settings or unsynced files. After backing up your scans, go to the same menu and select Clear Data to see if that resolves persistent crashes.

Confirm permissions and disable overlay apps

Ensure CamScanner has permission to access camera, storage and maybe microphone if using OCR. Also check that no other app is interfering via screen overlay or drawing permission. These conflicts often lead to crashes in scanning apps. By addressing this, you further your efforts to fix CamScanner crashes on Android.

Manage heavy resources and optimise performance

Limit app memory usage and disable large scans temporarily

If you’re scanning large documents with many pages, or using high-resolution settings, the app may crash because of memory overload. Try scanning fewer pages or reducing image quality to see if stability improves.

Remove or disable unused features inside CamScanner

Features such as auto-crop, OCR, cloud backup and sharing sync may strain older or lower-end devices. Temporarily disable those you don’t need and test the app again. These changes help fix CamScanner crashes on Android by reducing load.

Free up device memory and avoid background apps

Close other memory-intensive apps (games, streaming) before using CamScanner. Ensuring enough free RAM and minimal background load further lowers crash risk when you use the app for scanning.

Update device drivers, clear system cache & check compatibility

Update Android system and camera drivers

If your phone receives updates, install them—especially patches for camera drivers or Android stability. Many scanning apps rely on camera APIs which may malfunction on outdated versions.

Clear system cache partition (for phones that allow it)

On some Android devices you can clear the system cache partition via recovery mode. That may solve lingering system issues that cause app crashes.

Validate device compatibility and install official version

Ensure you’ve installed the official CamScanner version from Google Play, not modified APKs. Report shows that earlier versions of CamScanner had malicious modules and required safe update. Android Authority+1
Making sure your version is legitimate is part of fixing CamScanner crashes on Android.

Uninstall and reinstall as last resort

Uninstall the app completely

If none of the previous steps work, uninstall CamScanner. This removes all app files and lets you start fresh.

Reinstall from Google Play and test

After uninstalling, reinstall the latest version from Google Play. Then open the app, sign in and check if the crash issue persists. Often a fresh install clears deep-rooted faults and helps fix CamScanner crashes on Android.

Restore scanned documents and monitor behaviour

Once reinstalled you can restore your backed-up scans and test full functionality—scanning, saving, sharing. If it runs smoothly, you’ve resolved the issue. If not, consider device-specific or hardware problems which may require support.

Preventive measures and good habits

Regularly update the app and OS

Keep both the CamScanner app and your Android system updated. Updates often contain fixes for bugs that cause crashing.

Avoid scanning extremely large documents in one go

Split your document into smaller batches if possible. This reduces strain and improves stability.

Clear unused files, backup and manage storage

Low storage triggers many crash issues. Clean old files, move large media to SD/Cloud and maintain at least a few hundred MB of free space. Adopting these habits reinforces your ability to fix CamScanner crashes on Android systematically.

When to seek further support

If after trying all steps you still face crashes, consider the following:

• Check for hardware issues (camera malfunction, faulty storage)
• Contact CamScanner support or visit their help center
• Look for alternative scanning apps if your device remains incompatible
  While this isn’t the typical scenario, recognising when the issue lies outside the app itself is important in your overall plan to fix CamScanner crashes on Android.
