Choppy call audio after MM upgrade w/VoLTE

2016-01-05, 16:20 PM

I have a Moto X Pure Edition on T-Mobile. After the Marshmallow upgrade, the in-call audio quality is choppy in the following situation:



  • Advanced Calling enabled (Settings->More->Cellular Network->Enhanced 4G LTE Mode)

  • Make or receive a phone call

  • Put the phone up to my ear so that the screen turns off



The other person doesn't experience any issues but I hear choppy audio almost every time. If I take the phone away from my ear and the screen lights up, the audio becomes normal and smooth again. If I use Bluetooth, the audio is smooth. If I disable the Enhanced 4G LTE Mode, the audio is smooth.



Has anyone else seen this? I can perform additional testing if needed but this is pretty consistent.

I've been experiencing the same issue you have. All the same settings such as having the VOLTE turned on and having the phone up to my ear. I also have T-Mobile as my service.

Would be great if someone can find a solution to this or at least if it's a known issue. Hopefully Motorola will be able to get this worked out in a future update.

This also occurs on both mine and my wife's MXPE since upgrading with the same symptoms.
We are also on T-Mobile.

I'm also having the same issue with choppy call quality. I'm also on the T-mobile network. It started to happen the very next day after the update.

Have you tried to see if the audio gets better with the screen on (e.g. take the phone away from your head)? It seems to be a common workaround.

I tried that also clearing the cache on the phone same problem. I don't know if it's a network issue or software issue. I don't think it can be hardware because the speakers sound perfect when listening to movies or music. One thing that I did figure out is everytime I call my brother or he calls me the call quality is perfect and clear but every other call I make or receive has that choppy call quality.

I have this issue as well on T-Mobile.  Appears to be related to the phone entering an in-call standby mode when the screen turns off.  When the screen is off, changing the volume will also correct the problem for a few seconds until the phone goes back to sleep. 



I have noticed it in regular calls, speaker calls, and headset calls.  The only way I have found to get good audio is to keep pushing buttons to keep the screen alive.  



This is rather annoying since I use this phone for long work calls.

I've asked the team to take a look. If possible please make sure your forum profile includes your correct serial number and phone model. Thanks.

Also, can you post where you live, generally? Maybe ZIP code?

Hey Matt,



I live in 78753, but I've also reproduced it while traveling in Chicagoland (60060), Houston (77494) and Minneapolis area (55420) over the holidays.



My model and serial number are up to date.
