When calling someone with speakers on, they hear a strong echo of their own voice (I don’t hear any echo on my end). I tried with Signal and the phone app, and it only happened in Signal. I am sure it didn’t happen with my previous phone.
I tried this when calling an iphone and an other android, happened with both.
Looks a lot like the issue for the Galaxy S7.
Anyone else experiencing this issue ?
Phone: Fairphone 3
OS: /e/ stable 0.9-2020072965352 (happened with previous version as well)
Echo in apps:
Facebook Messenger: Yes
EDIT: Tried on more apps (see above for results). Plugging in headphones or stopping speaker mode stops the echo. If the phone is in speaker mode, it does not use the same mic as normal calls, so this might be the source of this issue.
It’s very strange as a problem, and by the way Signal has no settings to change regarding voip calls.
The only one that comes to my mind is this: in the privacy section, activate the “Always relay calls” function, because maybe by making the data stream of the call take a different path, maybe this annoying problem could disappear.
But it’s just a hypothesis
This problem is common to a lot of phones. I use a Samsung Galaxy S5 and have exactly the same problem with Signal and any number of SIP clients. There seems to be no solution although turning down the volume sometimes lessens the echo enough for the person on the other end to not abandon the call. Very frustrating.
For me, earphones are, figuratively, a pain in the arse. Scrambling to plug them in to the phone in order to answer an incoming call before it is abandoned or goes to voicemail raises my heart rate a bit too much.
OK, if anyone’s still here, the problem seems to be due to the noise cancelling mic picking up sound from the earpiece/speaker. It’s a common problem with non-stock ROMs and, as far as I am concerned, the main barrier to sticking with them. Recently I had to go back to stock on a GT-I9300 because I intend using it as a doorbell/intercom. This necessitates use of the speakerphone setting which produces intolerable feedback on /e/. Going back to stock fixed it immediately. Being so outdated brings its own problems but that’s a story for another day.
Moto phones seem to have varying degrees of echo problems in ‘voip’. I can confirm that Moto E2 (surnia) generates a very bad echo that apps like Signal can’t eliminate, whereas Moto G4 Play (harpia) works without echo when using Conversations or Signal.
Other apps like aTalk will also result in an echo on harpia. So it seems also apps have varying degrees of additional echo cancellation.
