A. 1. Check device compatibility: Ensure that your device supports multi-touch functionality. Some older devices may not support this feature. 2. Update the app: Go to the Google Play Store and check for any updates for CetusPlay. Install any available updates. 3. Enable multi-touch in settings: Open the app, go to settings, and look for an option to enable multi-touch gestures. Make sure it is turned on.

B. 4. Test with another device: If possible, try using CetusPlay on a different Android device to see if the issue persists. This can help determine if the problem is with the app or the device.
