Tmobile wifi calling issues

Anyone else having issues with wifi calling? Initially people were complaining they could not hear me or constantly telling me to repeat myself. I left myself a voicemail on my work phone and was surprised how low the volume was. It's as if the mic gain was turned all the way down. I had to turn the volume to maximum just to makeout what I was saying. Additionally, the earpiece volume is also a tad low on my end. I'm assuming it's safe to say there is nothing I can do till Tmobile updates the phone, right?

I just did a test on wifi calling to my voicemail at home and the volume was fine, sounded like a normal call. There was another voicemail on there as well from someone else and it was the same volume as theirs.

Hmmm...weird. I have no issues with mic volume during regular cellular calls and Skype calls (tested these two by leaving myself voicemails also).
I will call technical support and see what they have to say.
Thanks for the reply Robertsonland

I haven't had any issues (I had latency and sound issues on my Samsung Vibrant and Blackberry Curve before that using UMA) on my Sensation using Wifi calling yet. I used my friends phone while making a wifi call to it, and there was no delay at all, and the sound is great.

Bump. No one else is having low mic outgoing volume issues with wifi calling?

Constant. Wifi Calling is unpredictable. I have no network reception and the phone struggles to keep on wifi calling. I have tried most available roms all the patches and three devices. WIFI Calling is unreliable while using the phone. It works fine when left alone 90% of the time. However those times you pick up the phone and it doesn't show Wifi Calling, or it just then kicks in; you are catching it in its moment of sudden tmobile retardation. And i have tried it will all sorts of access points, obsessed over dd-wrt settings for weeks. Even ended up bricking a couple devices (JTAG ftw).
S-OFF Sensation LeeDroid 1.2 1.3 TMO-US Wifi Calling v1.0

If it's going in and out of WiFi calling like that it's the Sensation's WiFi reception causing the issues.

Do you put your hand over the top part of the phone when you're on a call?

My friends complain that they can hear themselves. Like an echo effect.

Happens all the time with me and my wife...to the point that I don't use wifi calling anymore. It is certainly a problem.

echoing on speakerphone has happened to me, solution.. don't use speakerphone.

Well I'm glad I found this thread because I am having the exact same issue and was going to return my Sensation. I have no regular cell signal in my house so I have to rely on the Wifi calling and it sucks from time to time. I have to repeat myself and sometimes the other person can't hear me even if I'm yelling in the handset. So from what I've been reading, it sounds like this is a normal (abnormal) wifi calling issue with Tmobile. That sucks!!! Is there any fix or possible bandaid for this problem?
Does this only happen with the Sensation or are others having this problem with other phones?

Bumb
Anyone have found a solution to this issue ?
I just joined Tmobile and i an having the same issue .
Microphone seems to be very week and i sound far away when i call using wifi .
Tried to hold the phone in different positions and i am using a case but no changes .

I have the same issue sometimes too, If i try to turn on speaker phone the mic cuts off all together. Using Revolution HD

You know .
I truly do not believe its a reception ( wifi reception or anything ) .
I ran packet capture and it all look`s "ok" no drops or resets .
This thing looks like a poor VOIP decryption , either on the phone or the Tmobile servers.
IT IS a software issue . And defenitly need to be attended to .
what i did notice that i have a sensation and so do my wife .
I get the issue she doesn't .
The difference i rooted my machine ( still uses original ROM i have a trust issue regarding running some unverified kernel`s ) .
Any thoughts ?

I have called Tmobile about the issue. The tech I talked to said there were no other reports of low mic volume. My mic volume works perfect when using Skype or SIP. But when on Wifi calling, the mic gain is way too low. I have left myself test voicemails, and I have to have the volume cranked all the way up to hear myself. Hopefully the issue will be resolved with the next software release.

Man that sucks .
This Wifi calling is cool and i like it , but if it doesnt work whats the point .
Any way to contact the development team of this product ?
Calling and talking to some dude in India at Tier I do not help here...

I have used several custom ROMs and Kernels and have had no issue with sound volume or quality using the WiFi calling app. It may be a simple hardware difference during manufacturing. Just as some people's phones work flawless while OC'd and others crash even though they all have the same model CPU. I would try to get a replacement phone to see if it works better.

I actually have another 2 new phones next to me .
Any way to clone my OS (including the config and everything ) to the other phone ?
Then i can move my SD and SIM .

Really confused! Audio drops during calls

Something very weird just started happening with my SamChg.
When I am a few minutes into a phone call (about 3 - 4 minutes), all audio drops out on both sides of the call. The call is still connected, but neither side hears anything anymore.
I did a factory reset on the phone, but it didn't make a difference.
What can be causing this? If I can't use my smartphone as a phone, I'm screwed!

are you running any special ROM or anything because its happening to me as well

I have been having the same problem for almost a month now. I was rooted when this started happening. I went back stock still happened. New 4g card still happened. Another phone still happened. I have been getting the runaround from verizon the whole time they have no clue what is going on.
On a side note asked a friend that works at a little vzw store if they have seen this problem and sure enough she had. She told me that they had a customer go through 4 phones and she started making calls and was told by Customer Support that it was a known thing and there was a software update coming out for that.
After hearing this I called good ole *611 yet again and they were clueless and said they knew nothing about it. *sigh*

Umm can't even remember now was a month ago LOL. But my 2nd phone I didn't put one app on or anything left it bone stock and still had the same problem. Same as the customer my friend had they would mess up right out of the box.

probably weak antenna

no you don't lose signal call keeps running you lose Audio.

Yes, I am running a custom ROM, but it's basically a stock rooted & voodoo'd EE4 ROM (by danalo1979, I think). It's got all the yucky poo-brown colors and all the bloatware.

Same issue here. I'm running completely stock right now, non-rooted. Sometimes the audio will drop at the onset of placing a call (I won't even hear ringing) and sometimes it will happen a few minutes into a call. Other parties do say they can hear me though.
Personally, I've noticed that this problem only happens when I am also connected to a Wireless Network. If I'm running 4G/3G, sometimes I hear echos of my voice, but the audio won't drop out.
Weird, but glad to know others are having this issue and that VZW is aware it's happening.
What should we do? Personally, I'd like to wait for the SG2 to arrive before I start complaining. My plan would be to basically flip out explaining that I need my phone to work like a phone, etc. Then flip out that I paid for 4G and my decision was battery based (so I don't get stuck with a Thunderbolt). I bet I could talk my way into a new SG2 over this... Just saying.

Well they do not tell me they know what is wrong they tell me they have no clue. I even explained to them somebody there does know as they have explained the issue to someone else that has had the problem but I still get they you just need another phone speel.

I don't have this problem watch as soon as I try to make a call the audio drops...

same, don't have this problem but i probably just jinxed it.

I've had this happen a couple times too...hard to pinpoint consistency. The other thing I've encountered more than once, is that my mic seems to go off mid-conversation, e.g. I can still hear the person on the other end very clearly, but they can't hear me. Anyone else experience this?

I've experienced that. But I'm not so sure I'm not just covering the mic with my finger.

I was on nluetooth, with the phone in the cupholder... Don't think my finger was involved.

Well 2nd Fru and as I told them it would. It does the same thing. Bone stock. *sigh*

One thing that seems odd to me is that I seem to see this problem more when calling another mobile phone vs. a landline.
Maybe it's just my imagination, but I always see problems when calling my wife's mobile phone. Last night, I called a landline for over an hour without any problem.

same here I can talk to customer service for 1hr+ but mobile to mobile most Ican get is maybe 15 min.

I drive around as part of my job and today I tested a call out to my wife who has a charge as well and we were able to talk for over 20 minutes with no issues. That same area I drove through a few days ago caused 3-4 drops in audio before. So in my opinion its a network related issue and hopefully its get fixed 100% cause most of us need our phones to work solidly

To the people losing audio during their calls, can you post your location?
The reason why I ask this is because on the Verizon forums there is an eight page post about this issue. Seems like a lot of people in Arizona are experiencing this. I'm in Chandler, Az and have this issue, especially when calling other VZW people in AZ.
Can't post links yet but check the VZW community forum for the Charge.

My pixel mic sometimes are not working during a call

Hi,after using my pixel for a couple of weeks,i found sometimes I can't hear anything , my mic is not working,people on the phone can't hear my voice too.
and when it happened I have to reboot the phone to let it working again. Anyone has a solution of this?
My country desn't have pixel in market,so I can't ask for a replacement.thanks

I did a hard reset on mine and it seems to have resolved the problem. Verizon was convinced it had to do with my WIFI calling setting. I just did this today so this is no indication of a long term solution. Mine also, when I received a call, would drop the first 3 to 5 seconds of my end of the call. Callers didn't know I had answered.

https://productforums.google.com/fo..._gxTpXX3s;context-place=forum/phone-by-google
Big issue on some phones. I had to get mine replaced. Google just admitted today it's HW related. See that link. Hope this helps.

The last post of which says,
To answer some of the questions that have come in on this thread over the holiday break:
*If you are experiencing failures of one or more microphones on the device, there is no known software fix. So far, we've traced all failures back to hardware problems (normally a faulty internal connection).
*Since it's a hardware failure, you need to return your device for a replacement. Normally, the fastest way to do that is from the merchant you purchased from. If that's not possible, you can go direct to Google, but it will take a few weeks as we must receive the device before shipping a replacement. Replacements will be "refurbished" but should be like-new: no impaired performance nor any cosmetic flaws.
*If you are returning your device, I don't need to collect RMA numbers here because we are automatically gathering all devices with mic issues for forensic investigation. Just make sure your reason for return is recorded as "microphone failure" or similar.
*If you are not located in the country where you purchased your Pixel, you'll need a friend in that country to process the return and forward you the replacement.
Sorry for the trouble and happy new year.

I had half of this problem. I could hear people but they couldn't hear me. I turned off wifi calling and advanced calling a month ago and haven't had a problem since. Don't know if it will help you but it can't hurt to try.

I have had that too, i think its related to wifi calling because what really pisses me off is that when im at home i have wifi calling because my phone is connected to wifi and i get in my car and if i make a phone call as soon as i leave the range of wifi the phone disconnects, never had this problem on the iphone. I really love this phone but some small things like this really irritate me.

sprint u11 stock Android 7.1.1 mute while on a call

Hi guys
I just got new u11 from sprint. I was very excited about this phone until I started to notice that the phone goes on mute while I'm on a call. The mute icon is not pressed. I usually click it to activate then deactivate it and it brings it back. Sometimes I hit that and speakerphone until the caller can hear me again. It's pretty frustrating. I searched online and it appears to affect many phones with 7.1.1, so I'm not sure if replacing the phone will cure this issue. I'm still within my exchange period but wanted to check with the community if there's a solution to this annoyance. It looks like it's affecting many phones and the users are pretty pissed off about it. Is there a fix from either sprint / HTC or Google ? Any advice is appreciated!

I suggest a factory reset first...since you just got the phone, you shouldn't have much to lose (and as a XDA user, you really have no reason not to be backed up somewhere....).
My second suggestion is to bring it to Sprint and let them fix/repair it, especially since you are within the return period.

Hi I did the factory reset without restoring any apps settings and the problem remains where during the call it goes on mute in and out. I called sprint and requested a new phone since this is either a hardware problem or bad sprint rom flash from factory. I went with a new phone route since I didn't want to waste the 14 day return/replacement period. Hopefully the new unit will work as expected out of the box. It's funny that a lot of people seem to have this issue on different brands.

Nothing to do with HTC and/or Sprint specifically. It seams to be a new feature if Android and is bound to the OS version 7.1.1 and upwards. OEMs can't do anything about it. Got it as well on my unit, bit when I activate knock on feature when in call it still does work as on previous versions, thus I don't care about the automatic DND during call in any way.

You can activate a knock feature for a second incoming call when talking on the line already. Sorry the knock on should try to describe this one.

You guys are talking about 2 different things.
One is micrpohone mute in call (seems like a bug) and the other one is DND mode while in call (seems like a feature).
I don't experience the behaviour you experience with calls on European model.

yes it's DND while on call, but it's not pressed/activated. i'm getting new phone anyways and will see if the issue persists. it's very annoying and not a good first experience with U11. i'm not sure if this is a software or hardware bug but this shouldn't be happening with a new device out of the box.

So what is it then?
1. DND while on call? It's nornal, you got your answer and new phone will act the same. It's not a bug.
2. Microphone goes on mute automatically and caller can not hear you? That's what you said in first post. It might be a bug.

I receive a call and after some time ( varies from few seconds to a min) the caller can't hear me. I put them on speakerphone they can hear me. Switch speakerphone off they can hear me again via normal call. It's ****ing frustrating. It's happening with a new replacement phone from sprint. I'm thinking about giving up on this u11 and getting galaxy. Its unlikely that it's a hardware issue on two new phones twice in a row

I have this same issue I also have several people tell me that they've called me several times yeah I have no missed calls I also have a strange text messages from the number 9479 and their blank

Hi Yaboc,
John here in Ireland and I'm having the same issue with my European HTC U11 and I feel your pain. I've been doing some Googling on the issue and have seen that (on previous HTC models anyway) it may be if you have Bluetooth on, the phone tries to connect to devices to pass the audio through and this is what causes the muting of the call. Do you have bluetooth switched on when the problem occurs? I have Bluetooth permenantly on for connecting to my Moto 360 watch so will try when I get home from work today to see if the problem still occurs if I switch Bluetooth off.
I'll be sure to let you know how I get it and just thought I'd share with you what I've read elsewhere online.
Here's the article I was on about earlier:
https://thedroidguy.com/2015/08/how...-cannot-be-heard-other-related-issues-1047469

Anyone having these issues (Call related) with their OP6?

So far this phone has been growing on me but there are 2 things that have peeked my attention....
Yesterday I was on a call with a coworker and hung up... the problem it even though it said it hung up I could hear him and his wife talking for about 10 minutes (I was working on something with my hands and wasn't at a stopping point yet). The only way I could break the connection was to reboot the phone... Clearly this can be horrible, people who I talked on the phone with may be able to hear me after I close the connection? Can get me in a lot of trouble.
Also I seem to have call audio dropping out or call drops when I am on a drive. I have T-Mobile and didn't have any call issues with my S8. Anyone else having weird call issues?

Yeah, just had a similar occurence yesterday.
And, I'm experiencing call quality problems, at least when signal strength is not great (although I didn't have problems with my OnePlus 3 at the same places), as written here: https://forum.xda-developers.com/oneplus-6/help/calls-barely-hear-calls-t3795664.
I'm currently trying to get it narrowed down with OnePlus-Support. Possibly, only SIM2 is affected, still investigating. But I'm pretty sure, there are all software-related, as signal strength itself shows more or less the same values as other devices.

I had a friend tell me yesterday he could hear me talking after we hung up?
I am T-Mobile USA 5.1.5 Oxygen, and only using SIM slot 1.

Hey there
@joshuadjohnson22
Now that's a major concern, haven't seen any other reports though. BTW possible for you to share a video recording showcasing that the other person can be heard despite cutting the call?

That's scary, I love to talk **** about the person I spoke to when I hang up ????

i have had a similar case. but i also experience another issue the network completely disappears randomly sometimes. its only happened twice since i got the phone a simple restart fixes the issue right away. was thinking of replacing the phone but they state a 2 week wait period. was just wondering if i can get some insight on wether or not this would be software related as in my opinion if it were hardware it wouldnt work at all.

replying....

Well I would love to see if what you say is happening for real . I mean someone else hearing me even after disconnecting the call is so not what I want, in fact, not what anybody would want. That's not why I bought an OP6. So, do share a video if possible..
And the same goes for you @satnamgill

Just a heads-up for users who may stumble upon this thread in the future: call quality problems are mostly gone after updating to 5.1.6 (and replacing SIM-cards).
The "phone not hanging up"-problem did not occur again, so far.

OK -- so I am having some issues with TMobile phone calls...on 5.1.9 rooted with Magisk and just disabled Stereo mod and Viper (which I have used on other phones with no issue...in case this was part of the issue).
1) In car today, hugn up after call with wife, but it was definitely still connected even though phone app said it wasn't.
2) On phone (not earpiece or car BT) after talking for a while I stop and then the other person starts talking and I can't here them at all, then it is perfect -- this is over VOLTE (all my calls have been so far). Also looks like notifications might be coming down or the proximity sensor has something to do with it.
3) Making calls over VoWiFi take forever to set up -- like sometimes 20-30 seconds.
BTW -- using SIM 2 today because of VM issue, but I still have it...VM's deleted from OnePlus dialer come back...seem to need to delete them from crappy TMobile Visual VM app. BTW was using a Lineage OS based rom on LG G6 and VM within the dialer worked perfect on that one...
These sound familiar to anyone else?
MW

I have the same issue on OnePlus 6T... Scary... Good that I have submitted return request within 15 days...

And, I'm experiencing call quality problems, at least when signal strength is not great (although I didn't have problems with my OnePlus 3 at the same places), as written here: https://forum.xda-developers.com/oneplus-6/help/calls-barely-hear-calls-t3795664.
I'm currently trying to get it narrowed down with OnePlus-Support. Possibly, only SIM2 is affected, still investigating. But I'm pretty sure, there are all software-related, as signal strength itself shows more or less the same values as other devices.

Did software update fix your issue?

Hello
I have experince same problem TODAY. It has happend on sim2 , didnt try SIM 1. I increase the volume for the earphone And IT stop hangup the Voice. I dont know If this is a fix pe not.
PS. I can confirm that SIM 1 ia working fine. The problem is in the sim2.

Just a heads-up for users who may stumble upon this thread in the future: call quality problems are mostly gone after updating to 5.1.6 (and replacing SIM-cards).
The "phone not hanging up"-problem did not occur again, so far.

Did you ever faced the issue after the update? I faced the issue on OnePlus 6T and had to return the phone...

When you say same problem..you mean other side is able to hear you even after you disconnected the call?

Yes... The other side can not hear me And i can not hear IT, after some small time is working back again.
But for me IT solved quick. .. IT was a network problem in the zone i am living, IT was solved after 5 days.

Nope, I've never experienced any call-related problems since the update (and changing SIM-cards, so I'm not 100% certain it was the update).

OK -- so I am having some issues with TMobile phone calls...on 5.1.9 rooted with Magisk and just disabled Stereo mod and Viper (which I have used on other phones with no issue...in case this was part of the issue).
1) In car today, hugn up after call with wife, but it was definitely still connected even though phone app said it wasn't.
2) On phone (not earpiece or car BT) after talking for a while I stop and then the other person starts talking and I can't here them at all, then it is perfect -- this is over VOLTE (all my calls have been so far). Also looks like notifications might be coming down or the proximity sensor has something to do with it.
3) Making calls over VoWiFi take forever to set up -- like sometimes 20-30 seconds.
BTW -- using SIM 2 today because of VM issue, but I still have it...VM's deleted from OnePlus dialer come back...seem to need to delete them from crappy TMobile Visual VM app. BTW was using a Lineage OS based rom on LG G6 and VM within the dialer worked perfect on that one...
These sound familiar to anyone else?

Did the "not hanging up" issue solved for you yet?

I have not had any of these issues in quite some time (including the not hanging up).
I am using A6003_22_180915 build (not the most recent, but the one before). No Viper or stereo. The not hearing people issue may have been me not holding the earpiece directly over my ear -- it seems if you move the phone a little off you can't hear any more. I guess I have gotten used to it.
One long term gripe I have about this phone (really the only one) is that the vibrate is easy to miss. On my iPhone 6s I would never miss it while the phone was in my pocket or on a desk across the room -- I miss most calls when this is on vibrate no matter where the phone is.
