What should I do if there is an echo in Xiaomi 5 video call?

There is an echo in the video call. The initial judgment is a network problem. Suggestion:

1. Check whether the network signal of your mobile phone or the other mobile phone is stable. Please change your position and try in a place with strong signal.

2. If it is a Unicom 3G mobile phone, try to switch to the 2G network mode (Settings-More Settings-Mobile Network-Network Mode-GSM only).

If it is a 4G mobile phone, try to switch the network mode (Settings-Connect-More Networks-Mobile Networks-Network Mode -4G/3G/2G Network Mode or 3G/2G Network Mode).

3. Try to restart the phone.

4. Try to replace the mobile phone card.

5. Back up data (contacts, text messages, photos, etc. ) and try to restore the factory settings (Settings-Reset/Privacy-Restore Factory Settings).
