A. 1. Check Internet Speed: Use a speed test app to check your internet speed. A minimum of 1 Mbps upload and download speed is recommended for video calls. 2. Close Other Apps: Ensure no other apps are using bandwidth in the background. Close any unnecessary apps before making a video call.

B. 3. Switch to a Different Network: If possible, switch to a different Wi-Fi network or use cellular data to see if the lag improves.
