Phone call sounds garbled and robotic


    Every so often, maybe about once or twice a week, I will encounter this problem where I will make or receive a phone call and the call will sound garbled in general, but voices will sound robotic and unclear. Even the dial tone is garbled. This has happened while calling other mobile phones as well as calling a landline. Every time it has happened, I have been in an area with good coverage, normally full coverage or near-full coverage. If I am streaming music prior to the call, it will be choppy and have streaming issues when I end the call. The only method I have found to resolve it is to restart my phone, which is not an ideal experience.


    Has anyone else encountered this issue? I never experienced this when I was previously on the AT&T network and I'm concluding it is probably a network issue rather than a device issue, however I haven't ruled out either as a possibility. My device is a Moto G4 Play, which hasn't had any problems since I got it.

        Often times signal strength is not the best indicating of connection quality. However I do want to ask a few questions to try and narrow this down with you. When the issue of garbled voices happen is their some sort of pattern to it? Is it in a specific location or when doing a specific task (I.e can you repeat the problem reliably)? If it is a specific location do you know of anyone else with T-mobile service that can test the area or maybe own another device that you can test calls with?


        You mentioned restarting the phone was the only way to fix the issue but have you tried turning airplane mode on and off as a short term fix? It basically forces your phone to reconnect to the network like a restart does but takes less time. Just thought I let you know as a band-aid fix in the short term. Sorry for all the questions and I will do my best to help.

            I haven't encountered it for a about a week; it had been a few days since it last happened when I posted the original question. As for the questions posted above, I haven't been able to figure out a pattern. The few times it had happened I was driving and my phone was connected to my car via bluetooth. I was in different locations, only separated by a few miles, and with high coverage. In two instances it occurred while connecting to a mobile phone not on the T-mobile network and another time it occurred while connecting to a land-line.


            I've been unable to reproduce the problem consistently, and since it has only happened while in my car, I usually just stop trying to make the call until I can restart the phone. I can try airplane mode next time it occurs. Come to think of it, may it be possible that something in my car is messing with my signal? I've noticed the GPS has issues finding my location and updating while doing direction, but I just figured it was the device itself.

              I know this thread is old, but I have this issue all the time and I'm on the verge of needed to move away from T Mobile.  I'm actually on a conference call right now (for the last 30 minutes) and it's happened 4x.  Audio pauses, then goes very deep and slow until it "catches up".  Is there a known issue and fix?

                I have been having this issue as well. The phone will be stationed in one place and I will experience this.  I also could be holding the phone standing still and if I move my hand the call becomes distorted. I have a Note 9. It's extremely frustrating because I miss parts of a conversation
