Echoing on a Samsung Note phone call can be caused by a number of things, including the speaker volume, the microphone, or network latency. Here are some things you can try to fix it:
Adjust the speaker volume
If the speaker volume is too loud, the microphone may pick it up and create an echo.
Move the microphone away from the speakers
If the microphone and speaker are too close together, you may hear yourself on a slight delay.
Close background apps
Apps running in the background can interfere with your phone's normal operation.
Reset app preferences
Resetting app preferences can help rule out apps that might be causing issues with your phone's microphone.
Check your network latency
A delay in the transmission of voice packets over the network can cause echo.
Check your hardware
Malfunctioning or poorly designed hardware, such as phones, headsets, or routers, can contribute to phone echo.
