Hi! I see you're having trouble with the CamScanner app not working on your Android 10 device. To help you better, could you tell me what exactly is happening? For example, is the app not opening at all, crashing during use, or is a particular feature not working?

Meanwhile, here are some common steps that solve many CamScanner issues on Android 10 with WebKit-based browsers:

1. Clear the app cache and data:
- Open your device's Settings.
- Go to Apps > CamScanner > Storage.
- Tap "Clear Cache" first, then "Clear Data" (Note: Clearing data will reset app settings, so your saved scans might be affected if not backed up).

2. Check app permissions:
- Still under Apps > CamScanner > Permissions.
- Make sure Camera and Storage permissions are enabled, as CamScanner needs these to scan and save your documents.

3. Switch to the system camera inside the CamScanner app settings (if available):
- Open CamScanner.
- Go to its settings and look for a camera option.
- Change the camera option to “System camera” to avoid shutter or camera-related bugs.

4. Restart your Android device after these steps.

If the app still doesn’t work, please let me know:
- Are you receiving any error messages?
- Does the app crash, freeze, or just fail to open?
- Were you able to use CamScanner properly before, or is this a first-time issue?

This info will help me guide you more precisely. Looking forward to your reply!
