I tried calling three different people from my FP2 on Telegram and all of them hear their voice echoing. I do not hear any echo, they do. I called them multiple times and for long calls.
The weird thing is:
- Telegram calls work properly from the desktop application.
- FP2 microphone works properly with normal calls and Skype (I do not use Whatsapp).
- I could call via telegram without an echo using earphones (with the earphone integrated microphone)
So it does not seem to be an exclusively hardware nor an exclusively software issue, but rather a bad combination of the two.
On this forum I found a very similar issue someone had on Hangout (and someone stating the same happened with Signal) https://forum.fairphone.com/t/echo-with-google-hangout/15745
Do you have any suggestion? Does anyone have the same issue?
