        @markatrafik that is too bad! I really like ubports, and use only this... But embarrassing when people say they hear themselves... Do you thing that formating the phone and resinstall everything could help?

          @c_moi I am not a project developer at the moment and I can only assume that either this is a programming bug, or it is necessary to use some echo cancellation methods... in any case here we need the developers to take the Issue

            I looked up what they say on the Internet, and found that in 2018 there was a similar problem with Sony phones.
            The workaround was to turn off AEC (Acoustic Echo Cancellation) and NS (Noise Suppression) in the "vendor" stuff.
            For example this link:
            https://forum.xda-developers.com/t/the-echo-issue.3793902/
            We have in Redmi Note 7, also this set of mechanisms in sound preprocessing, with the same UUIDs
            I quote the file /vendor/etc/audio_effects.xml

                <preprocess>
                    <stream type="voice_communication">
                        <apply effect="aec"/>
                        <apply effect="ns"/>
                    </stream>
                </preprocess>
            

            Maybe this solution could help?

                @Markatrafik That sounds good... But I am not an computer scientist so I have no idea how to try to change this!

                    @c_moi Very sorry! In my case at least ~ 50% of the echo problem was a smartphone-case

                        @c_moi ... and yet the problem is not the phone case. I decided to return Android for now, restored backup of all partitions through TWRP, loaded Android, and decided to try this case, will this "echo" under Android. There is no echo, the caller not hear himself, even when this phonecase on the phone. BTW, some kind of problem with echo cancellation under UT!

                          There was recently a solution to this problem on the Pixel 3a. Can this solution also be implemented for the OP3(T)? Or was there already another solution here. Thanks.

                            I have the "echo on the caller's end" problem also... I find using earbuds seems to solve the problem... ymmv.
