A. 1. Restart your device: Sometimes, a simple restart can resolve performance issues. Turn off your device, wait a few seconds, and turn it back on. 2. Close background apps: Make sure to close any unnecessary apps running in the background that may be consuming resources. Use the recent apps button and swipe away apps you don't need.

B. 3. Reduce video resolution: If you are working with high-resolution videos, try reducing the resolution in the app settings to see if that improves playback performance.
