Hi there! I see you're having trouble with the QDI app not opening on your Android device. Let's try to get this sorted out.

To start, could you tell me if the app crashes immediately when you try to open it, or does it just not respond at all? Also, have you noticed any error messages or unusual behavior before this started happening?

Meanwhile, here are some easy initial steps you can follow:

1. Restart your device. Sometimes a simple reboot can refresh the system and clear minor glitches.

2. Clear the app cache:
- Go to Settings > Apps > QDI app.
- Tap on Storage.
- Select "Clear Cache." This removes temporary files that might cause trouble without deleting app data.

3. Force stop and reopen the app:
- In the same app info screen, tap "Force Stop," then try launching the app again.

4. Check for app updates:
- Open the Google Play Store.
- Search for QDI, and update if available. Running the latest version is important for compatibility.

5. Ensure there’s enough free storage space:
- Go to Settings > Storage.
- Make sure you have at least a few hundred MB free for the app to run properly.

If you’ve already tried these or the issue persists, let me know. We can then delve into more advanced steps like checking permissions, uninstalling and reinstalling the app, or looking at network settings.

Does this sound good? Is there any particular step you've already tried?

App not opening

Thanks for letting me know the app is still not opening. To help you better, can you share if you’ve tried any steps like clearing cache, updating the app, or restarting your phone? Also, do you see the app load partially before closing, or does it never open at all?

In the meantime, based on recent solutions for the QDI app on Android 10, here’s an updated troubleshooting approach:

1. Clear Cache and Data:
- Go to Settings > Apps > QDI app.
- Tap on Storage.
- Select “Clear Cache” first. If that doesn't work, choose “Clear Data” or “Clear Storage” to reset the app (note: this may require you to log in again).

2. Check for App Updates:
- Open Google Play Store, search for QDI, and update to the latest version if available. Developers often fix stability issues in updates.

3. Reinstall the App:
- Uninstall QDI completely.
- Restart your phone.
- Reinstall QDI from the Google Play Store.

4. Verify Network Connection:
- QDI requires an internet connection to work. Ensure you have a stable Wi-Fi or mobile data connection.
- Try toggling airplane mode on and off to reset network connections.

5. Review App Permissions:
- Go to Settings > Apps > QDI > Permissions.
- Make sure essential permissions like storage and network access are enabled.

If after these steps the app still won’t open, there might be an issue on the backend or compatibility with your device. In that case, you could also check out these tutorial videos that provide visual guidance to fix QDI app issues on Android:
