Hello. It's an interesting issue.
Unfortunately, we do not have any Xiaomi MI A1 to test in on... Software echo cancellation is normally enabled by default, but I'm not sure if it is used if hardware echo cancellation is misbehaving... Could you please send us logs of you calls with echo and logs of the echo calibration ? (enable it in "options" > "advanced" and send us logs from "about") Regards Peio Rigaux Junior Software Engineer Belledonne Communications, the company behind Linphone Linphone.org <https://linphone.org/> Le 20/08/2020 à 16:05, [email protected] a écrit : > Hi, I use Linphone Android client 4.3.0 (the last Google Play version) > on Xiaomi MI A1 phone with Android 9.
