Solved Galaxy S10e Echo Issues

[3C Technology]

Hi Guys

I have a Samsung galaxy S10e (SM-G970F)
Software version Android 9 (G970FXXU3ASIE)
3cx App Version 16.2.0.30 and also on the earlier beta builds

After installing the 3cx client and testing calls they work perfectly without any echo.
However after a few days of use i start to receive complaints of my call echoing to
the caller. Changing the echo cancelation setting to off and back on makes no
difference deleting the account and re-adding has no effect. If i remove the 3cx
app and re-download and reconfigure it works perfectly again.

Cheers

Hello,

Can you try to toggle the option Advanced > Car / bluetooth support (Telecom API) and see if this helps you?

Hi John

Funily enough i had changed that on monday when i reinstalled the app and have yet to have the echo issue return. I will monitor for a few more days and then reenable it to see if issue returns
and provide feedback.

Cheers

Good hear, just keep in mind that different telephony APIs and different models handle echo cancellation in their own way, so we include both methods.

Hi @JohnS_3CX

Ok confirmed that the setting Advanced > Car / bluetooth support (Telecom API) is the cause of the echo when enabled..
