Loop Back on wifi calls

I have the nexus 6p and I make most of my calls over wifi. I have a problem with loop back and I have to take it off wifi which is eating up mt data. Suggestions?

By loop back, I’m assuming you are experiencing echo. If that is so, then either you have a mismatch in the analog end of your network with a high latency, you have the echo canceling mic covered with a case, or there is something wrong with echo canceling software in the phone.

Have you measured the ping time (latency) of your network to east coast servers? You might want to do that with a phone app like OOKLA speedtest and from a computer connected to your network using WiFi. It should be under 150 milliseconds.

I wouldn’t hurt to make sure you have SIP ALG turned off in your router settings, and to make sure the neighbors WiFi isn’t using the same channel as you.

I just found this on another thread:

I’m working with Huawei right now to get an RMA for my device, and have done extensive testing with regular cellular calls and VOIP. These are my notes so far:

Symptoms

  • No symptoms directly observed by the user of the Nexus 6P

  • Caller on the other end experiences the issue: a loud and distracting echo of their own voice

  • Muting the 6P’s mic stops the echo for the other caller

  • Calls to Nexus 6P with** headphones **plugged into the 6P do not cause the echo issue

Likely Cause

  • Echo issue appears to be caused by a feedback loop in the acoustic domain on the Nexus 6P’s end

  • The other caller’s voice comes out of the 6P’s speaker and is incorrectly picked up by the 6P’s microphones

  • Voice Memo recordings will not demonstrate this issue

  • Voice Memo does not involve playback while recording, and therefore cannot form an acoustic feedback loop

Steps to reproduce

  1. Prepare the Nexus 6P to make and receive calls:
  • Insert a SIM card for normal phone calls, and/or

  • Install Hangouts Dialer, Facebook Messenger, or another VOIP app

  1. Call the 6P from another device, or call another device from the 6P (originating device doesn’t seem to matter)

  2. The person talking on the Nexus 6P will not experience the echo issue

  3. The person talking on the other device will experience the echo issue

  4. Issue is intermittent (sometimes lasts only 10-45 seconds, sometimes indefinitely)

  5. If the echo issue disappears, then to reproduce the issue while still on the call:

  • On the Nexus 6P, switch to speakerphone mode

  • Then switch the 6P back to handset mode

  • Person on the other device will then hear the echo issue again (for 10-45 seconds, or indefinitely)

Tests performed

  • Honor 8, standard voice call to Nexus 6P on T-Mobile: echo issue experienced on Honor 8

  • iPhone 6, standard voice call to Nexus 6P on T-Mobile: echo issue experienced on iPhone 6

  • Honor 8, VOIP call over Google Hangouts to Nexus 6P on Wi-Fi: echo issue experienced on Honor 8

  • iPhone 6, VOIP call over Google Hangouts to Nexus 6P on Wi-Fi: echo issue experienced on iPhone 6

  • Honor 8, VOIP call over Facebook Messenger to Nexus 6P on Wi-Fi: echo issue experienced on Honor 8

  • iPhone 6, VOIP call over Facebook Messenger to Nexus 6P on Wi-Fi: echo issue experienced on iPhone 6

  • Desktop computer and headset, VOIP -> standard voice call to Nexus 6P on T-Mobile: echo issue experienced on computer

  • Desktop computer and headset, VOIP -> VOIP call over Google Hangouts to Nexus 6P on Wi-Fi: echo issue experienced on computer

  • iPhone 6, standard voice call to Honor 8 on T-Mobile: OK

  • iPhone 6, VOIP call over Google Hangouts to Honor 8 on Wi-Fi: OK

  • iPhone 6, VOIP call over Facebook Messenger to Honor 8 on Wi-Fi: OK

  • Desktop computer and headset, VOIP -> standard voice call to Honor 8 on T-Mobile: OK

  • Desktop computer and headset, VOIP -> VOIP call over Google Hangouts to Honor 8 on Wi-Fi: OK

  • Desktop computer and headset, VOIP -> standard voice call to iPhone 6 on T-Mobile: OK

  • Desktop computer and headset, VOIP -> VOIP call over Google Hangouts to iPhone 6 on Wi-Fi: OK

Analysis

Not a carrier issue

  • Nexus 6P still causes the issue whether using cellular network, or VOIP over Wi-Fi

  • Issue persists even with SIM card removed from 6P

  • Same SIM works fine in other phones (no echo when calling those phones)

Not an issue with the other phone in the call

  • The echo issue is experienced by the other person in the call, but is caused by the Nexus 6P

  • All tested devices encounter this issue only in calls to/from the 6P

  • Calls between every other combination of tested devices (excluding the 6P) are echo-free

Not a software issue

  • Nexus 6P was factory reset for testing

  • All available Google OTA updates were installed

  • Issue was present in Android 6 and persists in Android 7

  • After factory reset, new empty Google account was created for tests

  • During testing, no 3rd-party apps were installed except Hangouts Dialer and Facebook Messenger

The most likely remaining conclusion — unless this is a fundamental design flaw with the Nexus 6P that all users experience — is that there is a hardware defect with certain Nexus 6P units’ noise cancellation microphones.

I googled the issue and found that Huawei can fix the issue with a RMA and running marshmallow but if you update to Nougat the Google software update breaks the fix. The Phone can be rooted and a setting can be changed to help but to what degree of satisfaction I don’t have an answer to that.

I just bought in November from Republic and it came with Nougat

@pac0354

This has been an issue since the phone premiered Not something new but an ongoing issue.

Would have been nice to have seen that in the reviews when I shopping this site for a new phone

If I root it Republic voids the warranty.

Otherwise than the 14 day money back there is no Republic back warranty for them to void

Samsung provides the warranty

You may want to check to see if the conditions outlined by Republic apply … there is an open Master Ticket
