There could be several reasons why Call of Duty mobile is laggy on your Samsung Note 9, even though it runs smoothly on your Samsung Tablet. Here are a few things you can try to improve the performance:
- Clear Cache: Clearing cache data can help free up some memory on your device and might help improve performance. Go to Settings > Apps > Call of Duty Mobile > Storage > Clear Cache.
- Disable Battery Optimization: Sometimes battery optimization settings can interfere with game performance. Go to Settings > Device care > Battery > 3 dots menu > Settings > Sleeping apps > Remove Call of Duty Mobile from the list.
- Check for Updates: Ensure that the game and your device are up-to-date with the latest software updates. Check for game updates in the Google Play Store and software updates in Settings > Software update.
- Disable Power Saving Mode: Power Saving Mode can reduce the performance of your device, so disable it while playing the game. Go to Settings > Device care > Battery > Power mode > Turn Off.
- Disable Background Apps: Ensure that no other apps are running in the background while playing the game. Close all apps from the Recent Apps menu.
- Lower Graphics Settings: Even though you've already lowered the graphics settings to low, try lowering them even further to see if it improves the performance.
If none of these solutions work, it's possible that your device's hardware is not powerful enough to run the game smoothly.
