A. 1. Ensure your device is running the latest version of Android. Go to 'Settings' > 'About phone' > 'Software updates' and check for updates. 2. Clear the app cache by going to 'Settings' > 'Apps' > 'Trench Warfare WW1' > 'Storage' > 'Clear Cache'. This can help resolve temporary issues. 3. If the problem persists, try uninstalling and reinstalling the game. This can fix corrupted files that may be causing crashes.

B. 4. Check if your device has enough storage space. Go to 'Settings' > 'Storage' and ensure you have at least 1GB free. If not, delete unnecessary files or apps. 5. Restart your device to refresh the system and free up memory.
