Hi there! I understand you're having trouble with the Great Southern mobile deposit feature. Let's figure this out together.

To start, could you tell me a bit more about what's happening? For example:
- Are you getting any error messages when you try to deposit a check?
- Is the app not opening the deposit section at all, or is the deposit just not going through?
- Have you recently updated the app or your device?

While waiting for your details, here are some initial steps that often resolve mobile deposit issues on Android devices running version 10:

1. Check Internet Connection: Ensure you have a stable Wi-Fi or cellular data connection.
2. Update the App: Open the Google Play Store and verify that the Great Southern mobile app is up to date.
3. Restart Your Phone: Simple, but it can clear minor glitches.
4. Clear App Cache: Go to Settings > Apps > Great Southern app > Storage > Clear Cache.
5. Review Check Image Quality: When depositing, make sure the check is well-lit, fully visible, and all edges are within the frame.
6. Ensure Endorsement: Some banks require you to endorse the check by signing the back and writing "For Mobile Deposit Only."

If you’ve tried these already, please let me know which ones. There might be more specific troubleshooting steps, including checking account restrictions or app permissions related to camera access.

Also, sometimes mobile deposit services may be temporarily unavailable due to maintenance or network issues.

Let me know the details and what you’ve tried, and I’ll help you with the next steps!
