that you're experiencing lag and slow gameplay while playing Call of Duty mobile on your Samsung Note 9. It can be frustrating when your device doesn't perform as expected for a specific game. Here are a few suggestions to help improve your gaming experience:
Clear Cache: Clearing the cache of the game can sometimes help resolve performance issues. Go to Settings > Apps > Call of Duty > Storage > Clear Cache.
Close Background Apps: Make sure to close any unnecessary background apps before launching notice the game. This will free up system resources and ensure better performance. You mentioned using POCO Launcher, but it's also a good practice to manually close background apps from the recent apps menu
