Hello! I understand you're experiencing issues with the Sandbox app crashing on your new Android device. Let's work through this together to find a solution.

First, can you provide me with a bit more detail? For example:
- Are you seeing any error messages before the app crashes?
- When did you first notice this problem?
- Have you tried any troubleshooting steps so far, like reinstalling the app or restarting your device?

With this information, I can guide you better! In the meantime, here are some common steps to address crashing apps that you can try:

1. Restart Your Device: This can help clear temporary files that could be causing the issue.

2. Update the App: Ensure you have the latest version of the Sandbox app installed. You can check for updates in the Google Play Store.

3. Clear App Cache:
- Go to Settings on your device.
- Tap on Apps or Application Manager.
- Find and select Sandbox.
- Tap on Storage, and then select Clear Cache.

4. Free Up Space: Make sure you have at least 1GB of free space on your device as low storage can sometimes cause apps to crash.

5. Reinstall the App: If the above steps don't work, try uninstalling the app completely and then reinstalling it from the Google Play Store.

Let me know how it goes or if you have already tried any of these steps!
