Hi there! I understand you're having trouble with CamScanner on your Android device (version 10) because you can't connect offline and you also can’t log in to change your phone number. I want to make sure I get the full picture:

- Are you trying to use CamScanner without an internet connection and it’s not letting you log in?
- Or is the app not connecting even when you have internet?
- Have you tried to change your phone number while logged out or logged in?
- Also, do you currently have access to your email or any recovery options tied to your CamScanner account?

This info will help me guide you better. Meanwhile, I want to clarify that CamScanner requires internet connection to log in or change critical account details like your phone number. Offline use supports scanning and editing saved files but not account management functions.

Here’s a quick step-by-step of what you can try:

1. Check Internet Connection – Make sure your device has active Wi-Fi or mobile data because logging into your account and changing phone number needs to connect to CamScanner servers.

2. Log in online – If you didn't try yet, connect online and log in with your current credentials.

3. Change Phone Number – Once logged in, go to the account or profile settings inside the app to update your phone number.

4. Offline Mode – Offline use allows document scanning and editing but won’t allow login or account changes without connectivity.

5. App Update – Ensure your CamScanner app is updated to the latest version on Google Play to avoid bugs that might affect login.

6. Clear Cache – Go to Android Settings > Apps > CamScanner > Storage > Clear Cache. This can fix data issues.

7. Restart Your Device – Sometimes a simple reboot can refresh network connections and app behavior.

If the app still won’t let you log in or change your phone number despite having connection, there may be account or server-side issues.

Would you like me to walk you through checking your login and account recovery options? Or, if you are offline and need help with using the app features without login, I can provide tips for that too.

Please let me know!

Can not login "offline"

Thanks for clarifying that you’re trying to log into CamScanner offline. To confirm, CamScanner does not support logging in without an internet connection. The app requires an active internet connection to authenticate your credentials with its servers. This means you won’t be able to log in, change account details, or sync documents while offline.

However, you can still use CamScanner offline for some basic features such as scanning documents and accessing files already saved locally on your device. Just keep in mind that account-specific actions like logging in or changing your phone number require going online first1.

Here's what I recommend:

1. Connect your Android device to Wi-Fi or mobile data.
2. Open CamScanner and log in with your existing account credentials.
3. After logging in, update your phone number via the account/profile settings if needed.
4. Once done, if you go offline, scanning and viewing locally saved scans will still work without logging in again.

If you have internet but still can’t log in, please let me know. We can then try clearing cache, checking for app updates, or other troubleshooting steps.

Are you able to get online to log in, or do you want help using the app’s offline features without login?

I am online, data connected / wifi. Im chatting here online

Thank you for confirming you’re online and still unable to log in to CamScanner. Since your internet connection is active, let’s run through some targeted troubleshooting steps to resolve the login issue on your Android 10 device:

1. Check App Permissions
Make sure CamScanner has all the necessary permissions enabled, especially for storage and network access. You can do this by going to:
Settings > Apps > CamScanner > Permissions
Enable any permissions related to storage, camera, and network if they are off. App permissions can block the app from properly communicating with servers2.

2. Clear Cache and Data
Sometimes cached files can cause login or connectivity problems. To clear cache and data:
Settings > Apps > CamScanner > Storage > Clear Cache
If clearing the cache alone doesn’t work, try Clear Data, but note that this will reset app settings and you might need to log in again.

3. Update CamScanner App
Double-check that you are running the latest version of CamScanner from Google Play Store. Older versions might have bugs affecting login functionality3.

4. Restart Your Device
A device restart helps refresh system resources and network connections, which can resolve temporary app glitches.

5. Check Network Settings
Sometimes, VPNs or custom DNS settings can interfere with app connectivity. Try disabling VPN or switching between mobile data and Wi-Fi to see if it affects login success.

6. Verify Account Credentials
Make sure you are entering the correct username/email and password. If needed, try resetting your password from the CamScanner login page.

If you have done any of these already, please let me know which steps are done so I can tailor the next guidance accordingly.

If the problem persists after these, there might be a server-side issue or account-specific block, in which case contacting CamScanner support directly at [email protected] might be necessary.

Would you like me to guide you through any of these steps in detail?
