Sorry to hear that games like Clash Royale or Honor of Kings are closing right after launching – we understand how frustrating that can be.
First, you can try a few basic steps that sometimes resolve this type of issue:
• Clear the game cache
Settings → Apps → select the game → Storage → Clear cache
• Make sure the game and Google Play services are up to date through the Play Store.
• Check for a software update
Settings → Software update → Download and install
• Reinstall the game if the issue continues.
If the problem still occurs, please submit an error report through the Samsung Members app so our engineers can analyze the system logs 
.
