Hi there,
Unfortunately Echo in VOIP calls is already closed.
According to https://bugtracker.fairphone.com/project/fp2-android9/issue/25 the problem - callers hear their own echo in VoIP calls (messengers, SIP-apps, …) - should be fixed since Android 9 (beta 20.06.2-beta.0) in June.
Can anybody confirm that this problem does not exist any more?
Does anybody have an idea, wether this will be included in other operating systems (eg. Lineage OS 17)?
Cheers,
FM
